CPS Lighting supplies LED luminaires and lighting design support for industrial projects. At Yiyang Dongbu Industrial Park in Hunan, China, CPS provided 2,015 LED high bay lights for 83,835.52 m² of factory space, using 100W Polaris and 150W Uranus series luminaires.
The project combined two lighting configurations with illuminance simulation, scheme design and site guidance. Its scale shows why factory lighting needs to be planned around individual working areas, rather than selecting one wattage for an entire industrial park.

1. Project scope and supply configuration
The development is located in Yiyang High-tech Zone, southeast of the junction of Yuxingshan Road and Yuanshan Road. It includes eight production workshops, one pilot-production workshop, a shift-worker dormitory, a canteen and supporting facilities.
The development’s total building area is 111,846.13 m². The factory lighting coverage reported for the two high bay configurations is smaller: 83,835.52 m². The luminaire schedule below relates to that factory scope; it does not describe lighting supplied to every supporting building.

| Reported series | Rated power per light | Quantity | Reported factory area | Calculated rated total |
|---|---|---|---|---|
| Polaris | 100 W | 1,595 | 55,025.52 m² | 159.5 kW |
| Uranus | 150 W | 420 | 28,810 m² | 63.0 kW |
| Combined | Two configurations | 2,015 | 83,835.52 m² | 222.5 kW |
The combined rated power is calculated as (1,595 × 100 W) + (420 × 150 W) = 222,500 W. This is calculated rated power, not metered site demand. Actual energy use depends on operating hours, switching arrangements and the supplied equipment.
2. Lighting different factory spaces
The project account assigns the 100W Polaris lights to large production areas and the 150W Uranus lights to work areas described as requiring higher illuminance. Wattage alone, however, cannot establish the light level delivered to a work surface: mounting height, spacing, optics and room surfaces also matter.
The interior photographs show two distinct settings: concrete structural bays with overhead pipework, and an open hall beneath steel roof trusses. These views illustrate why lighting layouts need to account for beams, columns and services. They do not establish a fixture-by-fixture allocation between the two series.
For a similar factory, the design should check illuminance—the amount of light reaching the work surface—alongside uniformity and glare. Equipment and storage layouts should be included before installation, because they can introduce shadows that are absent from an empty-hall simulation. Final verification should use the agreed measurement grid and working-plane height.
No numerical site illuminance, uniformity or comparative energy measurements accompany the published case. The photographs document the installation setting; they are not a substitute for a measurement report.
3. CPS project support and manufacturing resources
For this project, the published account describes CPS support from illuminance simulation and scheme design through site guidance, acceptance and handover. This connects product supply with implementation support, while leaving the detailed installation responsibilities to the project’s contractual scope.
For new projects, CPS’s manufacturing resources include machining, cold forging, finishing and assembly. Its laboratory equipment covers photoelectric performance, electrical safety and environmental reliability testing. These resources support product development and quality control; individual test reports should be requested for the proposed model and specification.

| Calculated rated total | 159.5 kW |
| Current catalogue reference | GK-BJX; 100 W option; 14,000 lm; AC 120–277 V |
| Selection boundary | Catalogue values are not historical batch verification. |
| Parameter | Configuration or reference |

| Reported factory area | 28,810 m² |
| Calculated rated total | 63.0 kW |
| Current catalogue reference | GK-TWX external-power-supply version; 150 W option; AC 220–240 V |

5. Plan your factory lighting project
Send your factory plan or CAD drawing, building dimensions, mounting heights, work activities and required light levels. Include machinery and storage layouts, site photographs, electrical supply, operating hours and project location. For a retrofit, add the existing luminaire schedule and available energy records.
Request a free DIALux simulation to review a proposed layout and product selection. The simulation depends on the supplied geometry, surface assumptions and photometric data; site checks remain necessary to verify the installed result.
