H150 LED Lighting Retrofit at Shiheng Power Plant

CPS Lighting provides industrial LED luminaires and lighting design support. For the main building at Shiheng Power Plant in Feicheng, Shandong, China, CPS selected 110 H150 high bay lights rated at 150 W to replace 400W metal halide lamps.

The project had two linked requirements: reduce the lighting load and select equipment for a production environment with reported ambient temperatures near 50°C. The published case covers a completed portion of the main-building retrofit.

1. Replacing ageing metal halide lighting

The existing main-building lighting used metal halide lamps. According to the project account, the ageing installation no longer met production needs, and the owner wanted brighter working areas with lower energy demand. Equipment positions, working methods and visual comfort were part of the selection brief.

Configuration itemPublished or calculated value
Existing lamp rating400 W metal halide
Replacement productH150 industrial LED high bay
Replacement quantity and rating110 units × 150 W
Replacement rated total16.5 kW, calculated
Per-luminaire rated-power difference250 W; 62.5% lower than 400 W

The replacement total is 110 × 150 W = 16,500 W. The per-luminaire comparison is (400 − 150) ÷ 400 = 62.5% lower rated power. This arithmetic does not establish metered electricity savings. Actual consumption depends on operating hours, switching and complete-system electrical input, including any legacy ballast losses.

2. Heat management and light distribution

The main-building environment was reported to approach 50°C. The original case identifies a finned heat-sink design as part of the H150 selection. Thermal selection centred on that reported environment; a current replacement specification needs its own temperature confirmation.

For a similar installation, the proposed luminaire and driver should be assessed together against the temperature at their mounting position. The product specification, thermal test conditions and installation clearances need to match the application. A heat-sink photograph alone cannot confirm long-term performance in a hot building.

The project photographs show large machinery, pipework, platforms and overhead lighting. These features explain why replacing wattage alone is insufficient: the layout also needs to consider shadows, working-plane coverage and light reaching relevant vertical surfaces. The source describes improved area lighting and vertical distribution, without publishing numerical results for those measures.

3. Reported progress and CPS support

The published account states that part of the lighting retrofit had been completed and that illumination in the treated area improved. It also states that energy use decreased. No numerical illuminance readings, defined uniformity ratios, measurement grid or metering records accompany the page, so these remain attributed qualitative results.

For this project, CPS selected the H150 configuration against the owner’s heat, lighting and energy requirements. For new orders, CPS’s manufacturing and customisation resources and laboratory equipment support a specification review. Request model-specific documentation for the proposed ambient conditions; general factory capability does not replace that evidence.

4. H150 project configuration

H150 is the historical model named in the case. A current product with the same wattage should not be presented as its equivalent without checking the thermal specification, driver arrangement and photometric data. The project view below documents the installation setting, rather than an individual product close-up.

For a comparable power-plant building, discuss the high-temperature lighting specification with CPS using the site conditions and layout. For new orders, confirm the proposed H150 configuration, temperature rating and supporting photometry before specifying a replacement.

5. Plan your industrial lighting retrofit

Send a plan or CAD drawing, mounting heights, machinery and pipework locations, site photographs and working activities. Include ambient-temperature information at the intended mounting positions, the existing lamp and ballast schedule, operating hours, electrical supply and project location. State the required lighting criteria for each work area.

Request a free DIALux simulation to review a proposed layout with matching photometric files. Thermal suitability, equipment selection and the site measurement procedure need separate confirmation. Compare the installed lighting and energy records on a consistent basis before accepting a quantified retrofit result.
