Light output & thermal control
Set wattage, lumens, CCT, CRI, flicker, beam, temperature-rise, lifetime, and lumen-maintenance targets.
Construction, finish & ingress
Define body and shade materials, grounding, insulation, flammability, IP rating, plating, coating color, and durability.

Factory questions
Questions to resolve before production
Which driver, LED, metal, glass, and assembly processes are performed in-house?
Do certificates and reports match the final model, wattage, and BOM?
Are photometric, temperature-rise, flicker, and aging tests run on production units?
How are component or firmware changes approved and traced by lot?
Common risks
- Certified sample and production BOM do not match
- Excess heat, flicker, or lumen depreciation
- Batch differences in CCT, finish, or shade color
- Broken shades or incorrect market labels
