One for All Build Tough

LED Bulb for Harsh Environments


With Par 38 appearance, BrightNess has developed this 5000 lumen industrial grade bulb with E26 standard head (E39 with adapter), IP66 waterproof, operating temperature at 220oF (105oC), Par38-5000I-50-70 specifically designed for all tough factory surroundings, especially for high temperature working area, like power plant, steel mill, and metal processing factory.

This picture presents the application in the hard‑drawn copper wire factory. The highest temperature of copper can reach up to more than 920°C (around 1700 ). Ambient temperature of the work site can be more than 60°C (140) in summer while daily temperature outside is around 38°C (101).

Par38-5000I-50-70 can be installed into traditional high bay mercury lamp by E39 socket base. Not necessary for exchanging the whole lighting fixture into LED, the work site can be upgraded to LED lighting and reaches real eco-friendly. It's also much easier for lighting maintenance in a factory.
