2. Four Core Technical Specifications
2.1 Efficacy tiers: configured to project conditions
We offer light-source solutions across four efficacy tiers, allowing clients to select according to electricity price levels and required payback period.
| Efficacy tier | Delivery status | Typical applications |
| 130–180 lm/W | Standard product line, available for high-volume rapid delivery | General industrial workshops, warehouses, underground car parks |
| 180–210 lm/W | Standard product line and custom orders | Shopping complexes, office towers, schools, hospitals |
| 210–230 lm/W | High-efficacy custom line; delivered values confirmed by third-party test report | EU Class-A energy-label projects, major municipal road lighting, sports stadiums |
| 230–280 lm/W | Laboratory-verified technical ceiling; not a mass-production commitment. Project-specific development available on request | High-tariff regions, data centres, off-grid sites |
Two points on efficacy data that clients should note when specifying products:
First, efficacy above 230 lm/W depends on low-current drive conditions. We apply an under-driven ("large horse, small cart") design strategy: reducing the drive current per LED package raises efficacy, lowers junction temperature, and extends service life beyond five years. During scheme design we therefore set the drive-current tier according to the actual power requirement measured on site, rather than quoting a peak figure.
Second, measured luminaire efficacy is typically 20%–30% lower than the nominal efficacy of the LED packages inside it. This is an objective characteristic of the lighting industry. All our quotations and scheme documents are based on measured luminaire values, not on package-level theoretical figures, so that no efficacy dispute arises at project handover.
2.2 95% driver efficiency and centralised DC supply
Our driver conversion efficiency reaches 95%. The prevailing industry requirement is a minimum of 90%, so 95% places losses in the power-supply stage close to their practical lower limit.
The value of this figure becomes clear in the context of total system losses: conventional discrete architectures lose approximately 7%–9% in energy conversion, making the power supply the second-largest loss point after thermal losses at the light source. In facilities operating 24 hours a day — warehouses, cold stores, data centres — a five-percentage-point difference in driver efficiency accumulates into a substantial electricity-cost differential over the product lifetime.
| Supply architecture | Energy-saving effect | Applicable conditions |
| High-efficiency single-luminaire driver (non-isolated / LLC resonant topology) | 95% driver conversion efficiency | Retrofit of existing buildings; no changes to the distribution system required |
| Centralised DC supply (250 V ±20 V DC) | A further 15%–20% saving on top of high-efficiency drivers, plus improved electrical safety | New-build projects, or retrofits where distribution can be modified; compatible with PV and storage systems |
Centralised DC supply removes the individual AC-DC conversion stage inside each luminaire and feeds luminaires from a common DC bus, reducing cumulative multi-stage conversion losses. Its cost constraint is that DC distribution equipment costs approximately 1.5 times the equivalent AC equipment. We therefore recommend this architecture for new-build projects with the necessary conditions, and high-efficiency single-luminaire drivers for retrofits, selecting the combination that delivers the best return on investment for the specific project.
2.3 System-level energy saving: three independent sources
Our energy-saving approach rests on three mutually independent sources. A client adopting only one or two of them still obtains the corresponding share of savings.
Source 1 — Savings from light-source replacement. Replacing standard LED products with high-efficacy products yields significant secondary savings even where the site is already lit by LED. High-efficacy LED luminaires operate in the 180–240 lm/W range, and savings relative to standard LED products fall approximately between 20% and 75%, depending on the efficiency of the equipment being replaced.
Source 2 — Savings from system-loss control. Four engineering measures reduce transmission losses: selecting low-current LED package bins (a 0.2 W bin delivers higher efficacy than a 1 W bin); under-driving packages, which raises efficacy by 10%–15%; replacing frosted PC diffusers with high-transmission diffusers, which raises efficacy by 10%–12%; and using high-efficiency power supplies in non-isolated or LLC resonant topologies, combined with 95% driver conversion efficiency.
Source 3 — Savings from intelligent management. Sensing and algorithms reduce hours of unnecessary illumination. Published industry data indicate combined savings of 60%–95%, with the actual figure depending on the proportion of unoccupied hours in the space.
Qualification of the "60% energy saving" claim: 60% is an attainable target value for most commercial and industrial scenarios under a combined "high-efficacy hardware replacement plus smart-control configuration" approach. It is not a uniform guarantee for all projects. The actual saving in any given project depends on four variables: the efficiency of the existing lighting installation, the measured occupancy profile of the site, the depth of the control configuration, and the quality of ongoing operation and maintenance. We determine each project's actual saving by parallel-meter measurement: meters are installed in parallel at the same metering point before and after the retrofit and read by the client or a third party, so the saving is demonstrated by meter data rather than estimated.
2.4 Longevity and reliability engineering
The true cost of a lighting project lies not in the purchase price but in replacement and maintenance. We treat reliability engineering as equal in priority to efficacy.
| Reliability dimension | Common industry issues | Our design control points |
| Thermal management | 40%–60% of input power in LED conversion becomes heat; inadequate heat removal causes efficacy droop. In high-power LEDs roughly 70% of input energy becomes heat, and conventional aluminium-substrate plus fin arrangements approach their thermal-resistance ceiling in compact luminaires | High-conductivity aluminium profile heat-sink structures; side-emitting body designs that reduce the temperature sensitivity of light source and optical components, stabilising output |
| Power-supply reliability | Temperature drift causes premature failure in a proportion of luminaires; the on-resistance temperature coefficient of standard MOSFETs can reach 10% at high temperature, affecting brightness stability and efficiency | Under-rated design combined with RC filtering, rectification and conduction-tube protection to prevent excessive current or voltage reaching the driver circuit |
| Module consistency | Multi-chip parallel modules develop localised hot spots due to forward-voltage variation | Package binning and current-spreading structure optimisation to lower drive voltage and improve efficacy and uniformity |
| Lumen depreciation and lifetime | The prevailing industry lifetime benchmark is L80 at not less than 50,000 hours | Configured from the EU mandatory floor of L70/B50 not less than 30,000 hours, extendable to 50,000–100,000 hours according to project requirements |
| Sensing accuracy | Under strong interference, smart-sensing algorithms lack robustness; published industry data report false-trigger rates up to 28.4% | Millimetre-wave radar combined with AI algorithms, tuned to on-site interference levels, preventing lights that fail to switch on when needed or fail to switch off when vacant |
On warranty, we provide 5–10 years' warranty together with cloud-based remote monitoring (exact term as stipulated in the contract). This warranty period matches the contract cycles customary in European projects.

> The saving ranges in the table above are drawn from published industry sources and from measured performance of projects using comparable technical approaches. They are provided to help clients estimate a likely benefit range and do not constitute a performance commitment by our company. The saving for any specific project is determined by site survey and parallel-meter measurement.
3.2 Sector notes
Commercial and public buildings. Supermarkets, office towers, schools, hospitals and galleries share three characteristics: long operating hours, large floor areas, and high electricity tariffs. The absolute value of savings is therefore large and payback is short. In mall circulation areas, replacing 12–15 W standard LED downlights with 5.5 W units achieves approximately 59% saving. Across a whole office building, panels above 190 lm/W combined with sensor-controlled circulation lighting reduce building-wide consumption by 50%–70%. Schools and hospitals impose the strictest requirements on flicker, colour rendering and blue-light emission; we configure these to Ra ≥ 90 with RG0 available.
Sports and large venues. Stadiums, swimming halls, football pitches, arenas and tennis centres are technically demanding and high-value projects. LED efficacy of 130–185 lm/W compares with 65–100 lm/W for metal halide, so installed power for the same illuminance is only 50%–70% of a metal-halide scheme, with overall savings typically between 50% and 75%. Quality constraints in venue lighting are non-negotiable: instant start, flicker-free operation, high colour rendering (Ra ≥ 90) and stable colour temperature are required to meet HDTV broadcast demands for vertical illuminance up to 2000 lx and for uniformity. Venue-grade parameters we can supply include anti-glare lenses with transmission above 98% and luminaire efficiency above 95%; compared with a conventional 1000 W metal-halide fitting, a single LED fitting requires only 300 W with a glare rating not exceeding 30; illuminance uniformity not below 0.7 and glare index GR not above 35. For eight standard tennis courts, annual consumption can fall from approximately 83,000 kWh to 31,000 kWh. LED initial cost is roughly 1.5–2 times that of metal halide, but whole-life cost savings reach 50%–70%, with typical payback of 3–5 years for a medium-sized football pitch.
Industry and logistics. Overall savings after replacement typically fall between 50% and 70%, with payback between six months and two years — among the shortest of any sector. Ingress protection is commonly IP65/IP66, CRI not below 80, with batwing or precision-lens photometrics. Cold stores best demonstrate the value of smart control: published industry cases report lighting consumption reduced by 87% with payback of about one year. In warehousing, industry data indicate overall energy costs can be cut by up to 75%. Our industrial lighting modules retain 97% of their efficacy in extreme environments.
Municipal and transport. LED street lighting reduces consumption by 50%–80% against high-pressure sodium, with efficacy above 160 lm/W; combined with smart dimming, total savings can exceed 70%. China's 2025 revision of the national standard expanded road-lighting energy classes from three to five tiers, with the Class-3 entry threshold at not less than 120 lm/W and the Class-1 "forerunner" tier at not less than 170 lm/W. The evaluation framework has shifted from single-source efficacy towards "adapted efficacy", emphasising effective utilisation of light in the actual scene — meaning photometric precision matters as much as the efficacy figure. Underground car parks show particularly strong results because they are unoccupied for most of the day: AI radar sensing can reduce average operating power to 2–3 W.
Agriculture and special applications. In horticultural lighting the relevant unit is μmol/J rather than lm/W. The efficacy ladder runs from approximately 1.5 μmol/J for high-pressure sodium, to about 2.8 μmol/J for standard LED, to 4.1 μmol/J for quantum-dot LED; dedicated horticultural LEDs reach 4.6 μmol/J. LED reduces consumption by roughly one-third against high-pressure sodium and generates far less heat — a 320 W LED fitting emits 130–160 W of heat against 420 W from a 600 W sodium lamp — which directly cuts greenhouse cooling load. We configure spectra to crop type. Equipment rooms and data centres show the strongest published results, reaching 97% in industry data. Our high-efficacy technology also extends to visible-light communication (Li-Fi), transmitting data via high-frequency LED modulation with immunity to electromagnetic interference and no signal leakage, suited to defence, medical and industrial-internet applications with confidentiality or EMC requirements.

4.3 Sensing and algorithm capabilities (4 categories)
Protocols are transport channels; what creates an intelligent user experience is sensing and decision-making.
| Capability | Technical content | Energy-saving contribution |
| Occupancy and environmental sensing | Millimetre-wave radar enables single-luminaire energy and carbon management; AI radar sensing delivers light-on-approach and light-off-on-departure | 80%–92% combined saving in underground car parks; average operating power reducible to 2–3 W |
| AI prediction algorithms | LSTM algorithms for occupancy prediction, adaptive dimming and dynamic energy management | Combined saving of 60%–95%, depending on the proportion of unoccupied hours |
| Daylight harvesting | Artificial light output adjusts automatically to available daylight, with perimeter zones dimmed first; in agriculture, light-recipe sequencing control | Additional savings in offices and schools; system savings in greenhouses |
| Remote operation and maintenance | App-based group control, automatic fault alarms, cloud remote monitoring | Reduces inspection and manual maintenance cost |
Decentralised single-luminaire autonomy is the current technical direction: each luminaire makes its own decisions without a gateway, combining millimetre-wave radar with LSTM algorithms to achieve 80%–95% overall saving, with edge-computing response below 0.5 seconds. Its value is not only the elimination of gateway cost but also mitigation of the interoperability problems caused by protocol fragmentation — cross-protocol coordination happens at the device level rather than depending on a unified upper platform.
A cloud-edge-device architecture guarantees offline operation and millisecond-level response: if the network fails, local lighting logic continues to work, and data is back-filled automatically when the network recovers. We support IoT-based lighting networks compatible with MQTT, CoAP and BACnet, enabling integration and data exchange with building automation systems (BAS) and environmental monitoring systems.
4.4 Choosing between three system architectures
| Architecture | Advantages | Limitations | Suitable clients |
| Centralised (gateway + bus) | Commissioning is visible and faults are easy to locate | The gateway is a single point of failure; expansion is limited by bus capacity | Single buildings, projects with a defined scope |
| Decentralised (luminaire autonomy) | No gateway; device-level decision-making; cross-protocol coordination; flexible expansion | Slightly higher per-luminaire cost | Large campuses, multi-building estates, phased projects |
| PV-storage integration | Lighting becomes a dispatchable energy node rather than a pure load; can be configured towards carbon-neutral operation | Requires PV and storage investment | High-tariff regions, off-grid sites, projects eligible for storage subsidies |
4.5 Default protocol configuration by target market
We do not ship a single control configuration to all clients; we match the default to the prevailing baseline and usage habits of each target market.
| Target market | Default control configuration | Rationale |
| European municipal and outdoor | DALI-2 + Zhaga Book 18 + LoRaWAN / NB-IoT | The prevailing baseline for European outdoor lighting |
| European premium offices | KNX + DALI-2 + millimetre-wave radar | Building-automation integration requirements; supports green-building certification schemes |

| Chinese market | OneConnect / NearLink + Zigbee + NB-IoT | Support for the HarmonyOS ecosystem and indigenous protocols |
| Middle East, South-East Asia, Africa (municipal) | NB-IoT + LoRaWAN + 4G Cat.1 | City-scale deployment where fixed networks may be absent |

• Anti-reflection coatings using alternating silicon-oxide and titanium-oxide layers increase normal-direction output intensity
Scheme verification capability: we offer luminaire efficacy simulation and work with DIALux to provide a complete verification chain, delivering illuminance distribution plots, uniformity calculations and energy-consumption forecasts before order placement, reducing on-site rework.
6. Reference Data on Energy-Saving Performance
6.1 The pattern behind the numbers
Clients estimating their own project benefit can refer to the tiered pattern below. The saving achieved depends on the proportion of "unnecessary lighting hours" in the space: the longer a space is unoccupied, the greater the saving available from smart control.
| Setting type | Indicative saving range | Determining factor |
| Plant rooms, underground car parks | 80%–97% | Very high proportion of unoccupied hours; sensing can reduce lighting to near zero |
| Cold stores, warehouses, distribution centres | 60%–90% | Long operating hours combined with smart sensing; 24-hour sites gain most |
| Offices, shopping complexes, supermarkets | 30%-70% | High proportion of occupied hours; savings limited by the need to maintain illuminance |
| Schools, hospitals, galleries | 24%-60% | Predictable schedules allow time-based control, but CRI and illuminance requirements are high |
| Urban roads, tunnels, metro | 28%-70% | Night-time safety must be maintained, so savings come mainly from scheduled dimming; above 70% when smart control is added |
| Sports venues | 50%–75% | Low frequency of use but high power per event; whole-life cost savings of 50%–70% |
At the survey stage we first measure the site's actual occupancy profile, then decide whether to prioritise high-efficacy hardware replacement, smart-control configuration, or both. That decision determines the client's optimal return on investment.

6.3 Parallel-meter measurement: making savings verifiable
We determine project savings by parallel-meter measurement rather than theoretical calculation or estimation. Meters are installed in parallel at the same metering point before and after the retrofit and read by the client or a third party.
This verification approach is compatible with the Energy Performance Contract (EPC-RG) model promoted in the EU. Published sources record that an Italian province and metropolitan area achieved electricity savings above 80% in public lighting renewal through EPC-RG, with one tender guaranteeing a saving rate of 80.2% and delivering a 35% immediate budget reduction.
Globally, Lighting as a Service (LaaS) and "Pay as you Save" models are becoming established delivery approaches. We can offer both.
7. Export Compliance Capability
7.1 Market opportunity
In markets with high electricity tariffs and sensitivity to energy cost, demand for lighting efficiency is increasingly driven by regulation rather than relying on client initiative alone, which creates relatively predictable market opportunity.
Published industry data indicate that around 11 billion lamps are in use in Europe and that lighting accounts for 8% of primary energy consumption; replacing all conventional lamps with LED could save approximately EUR 65 billion in energy costs annually and avoid about 51 million tonnes of CO₂; and smart lighting management can achieve savings of up to 80% compared with conventional technology.
Published industry forecasts put the European LED lighting market at approximately USD 24.69 billion in 2025, growing from USD 25.86 billion in 2026 to USD 95.36 billion by 2034, a compound annual growth rate of about 15.5% for 2026–2034; LED already approaches a 90% share of the overall European lighting market. This means markets that have already completed LED conversion still have clear scope for a second upgrade cycle — from standard LED to a combination of high-efficacy LED and smart control.
7.2 Three EU regulations and our corresponding capabilities
| Regulation | Effective date | Core requirements | Our corresponding capability |
| ESPR (Ecodesign for Sustainable Products Regulation) | 18 July 2024 | 16 criteria including durability and repairability; introduction of the Digital Product Passport (DPP); light sources must be replaceable, failing which the whole luminaire is classified as a "light source" with a restricted energy label class | Replaceable light-source structural design available to meet ESPR requirements |
| ErP / SLR energy-efficiency rules | 1 September 2021 | Directional LED not below 120 lm/W; non-directional not below 140 lm/W; standby power not above 0.5 W; flicker SVM not above 0.4 and Pst LM not above 1.0; CRI not below 80; L70/B50 lifetime not below 30,000 hours | Our high-efficacy custom line exceeds the efficacy thresholds; flicker, CRI and lifetime configurable to standard |
| ErP labelling regulation | 1 September 2021 | New A–G seven-class label replacing the former A+++/A+ scheme; registration in the EPREL database with QR code generation required | We can assist clients through the EPREL registration process |
| EPBD (Energy Performance of Buildings Directive) | From 2028 | Non-residential buildings with HVAC power above 290 kW must be equipped with smart lighting control systems capable of demand response | Demand-response interfaces can be reserved in the control layer |
| EPBD | From 2030 | Scope extended to buildings above 70 kW; mandatory deployment of building automation and control systems (BACS) | BACnet/IP and Modbus TCP integration supported |
The three regulations form a combined threshold: ErP sets the floor for efficacy and flicker, ESPR sets requirements for replaceability and repairability, and EPBD sets control-system configuration requirements. Satisfying only one of them is not sufficient for market access.
Important note on energy labelling: under the current labelling rules, at least 210 lm/W is required for an A-class rating, whereas 120 lm/W corresponds to the former A++ rating that has now been abolished. The new label raised thresholds across the board, so formerly high-efficacy products are automatically downgraded under the new scheme. Our high-efficacy custom line (210–230 lm/W) can meet the efficacy requirement for an A-class rating.
7.3 Member-state incentives and procurement channels
Germany. LED conversion kit models convert existing luminaires to high-efficiency LED; published cases show savings of at least 50% in electricity consumption, with national subsidies able to cover costs within a few years. The Building Energy Act (GEG) requires new buildings to meet "Efficiency Standard 55", meaning primary energy demand not exceeding 55% of a reference building. Balcony PV (Balkonkraftwerk) grants reach up to EUR 500.
France. The light-pollution decree in force since 1 January 2019 applies to public and private outdoor lighting and aims to prevent energy waste and protect ecosystems. Commercial premises are required to switch off illuminated signage between 01:00 and 06:00 and to install remotely controllable switches in preparation for energy-tight periods. Public lighting must comply with NF C17-200 and EN 13201. The Energy Savings Certificate (CEE) mechanism provides financial support for efficiency retrofits, alongside corporate tax relief and the C3IV tax credit for green industrial investment.
Italy. The PNIEC plan requires public lighting systems to complete LED conversion. Lombardy offers grants of up to EUR 3,000 for PV-plus-storage projects up to 20 kW. The public procurement system maintains framework contracts for public lighting covering electricity supply, maintenance, energy upgrades and smart-city functions.
Spain. Accelerated depreciation applies without restriction to corporate investment in self-consumption renewable energy facilities. Administrative energy-saving orders set air-conditioning limits of 27 °C maximum and heating at 19 °C minimum for public buildings and shops, with shop-window lighting to be switched off at 22:00. The FEDER programme provides EUR 250 per kWh for battery storage systems. Published cases record a city replacing 350 high-pressure sodium sets with LED, cutting power by 65% and saving EUR 27,000 annually.
Sweden and the Nordic countries. Solar installation grants rose from 15% to 20%, covering materials and labour. Support for single-family home efficiency retrofits increased, and energy sharing between buildings is permitted.
7.4 Product definition for high-tariff markets
Combining regulatory requirements with available incentives, our product specification for the European market can be configured as follows:
• Whole-luminaire efficacy not below 210 lm/W, to correspond with A-class energy-label requirements
• Replaceable light-source structure, to correspond with ESPR
• Flicker SVM not above 0.4 and Pst LM not above 1.0; CRI not below 80
• L70/B50 lifetime not below 30,000 hours, configurable to 50,000–100,000 hours
• Standby power not above 0.5 W

Three accessible routes to market: the German LED conversion kit model corresponds to retrofit of existing luminaires; Italy's PNIEC requirements and public-lighting framework contracts correspond to municipal volume procurement; France's light-pollution decree and remote-switching requirements correspond to regulation-driven replacement.
8. Cooperation Models and Delivery Process
8.1 Three cooperation models
| Model | Client investment | Indicative payback | Suitable clients |
| Outright purchase | Single payment for goods | 6 months to 2 years for industrial settings; 1–2 years for commercial; 3–5 years for sports venues | Clients with available capital who wish to own the asset |
| Energy Management Contract (EMC) | No upfront investment | Costs recovered from a share of the energy savings; as short as 4–6 months for commercial lighting, typically 1–3 years overall | Clients who prefer not to tie up cash flow and wish to pay from savings |
| Lighting as a Service (LaaS) | Service-contract fee only | Contract covers the whole retrofit, maintenance and upgrades | Chain stores, multi-site clients, public institutions |
The credibility of the EMC model rests on parallel-meter measurement: meters are installed in parallel at the same metering point before and after retrofit, so the saving rate is established by meter data. We provide 5–10 years' warranty (as stipulated in the contract) together with cloud-based remote monitoring.
8.2 Four-step delivery process
Step 1 — Site survey. Measure the actual occupancy profile, existing illuminance and power, distribution conditions, and ambient interference levels. This step determines whether the project should prioritise high-efficacy hardware replacement, smart-control configuration, or both.
Step 2 — Scheme design. Deliver DIALux illuminance simulations, uniformity calculations, efficacy simulation results, energy-consumption forecasts and payback analysis, specifying all eight customisation parameters: efficacy tier, CRI and colour temperature, photometric distribution, ingress protection, driver architecture and control protocol.
Step 3 — Verification and testing. Sample measurement and client confirmation, baseline data collection by parallel metering, and commissioning tests between the control protocol and existing building systems.
Step 4 — Long-term operation and maintenance. Cloud remote monitoring, automatic fault alarms, app-based group control, periodic saving reports, and warranty service as stipulated in the contract.

Technical specifications. Efficacy, driver efficiency, lifetime, ingress protection, colour rendering and other technical parameters stated in this document are design target values and available configuration ranges. Delivered values are as agreed in the technical specification confirmed by both parties, sample measurement data, and third-party test reports. Efficacy data distinguish between measured luminaire values and nominal package values; measured luminaire efficacy is typically 20%–30% lower than nominal package efficacy. Efficacy above 230 lm/W depends on low-current drive conditions, and 280 lm/W represents a technical ceiling verified under laboratory conditions; neither constitutes a mass-production delivery commitment.
Energy-saving performance. Saving ranges stated in this document are indicative ranges for different settings. They are affected by the efficiency of the existing lighting installation, actual on-site operating hours, the depth of the control configuration, and the quality of operation and maintenance, and they do not constitute a commitment as to energy-saving performance for any specific project. The figure of "60% energy saving" is a target value for most commercial and industrial scenarios under a combined high-efficacy hardware replacement and smart-control configuration. The actual saving for any specific project is to be determined by site survey results and parallel-meter measurement.
