WaiChi LED High-Bay Review: Up To 80°C Operation Temp.

Recently the weather during summer season is hotter and hotter, many countries, regions record highest temperature since this year. And there are cases of wildfire from US, Europe, China etc. However, still there are many workers keep working in factories, construction site, and colliery. Absolute should be allowance for the high temperature for those workers.
During summer, the temperature in some plants are more than 60°C. And sine factories, they prefer using low quality high-bay for saving cast. But most of them are damage because of the high temp. Finally, they always have to repair/replace lamps when summer comes.
Today we are evaluating the LED High-Bay from WaiChi, developed for the application under 80°C.
Months ago FCS visited the factory of WaiChi with our clients. Through our audit it’s one of the top manufacturer for LED high-bay no matter in the strength of products or the capacity of factory. Detailed audit report of WaiChi.

Summary of Structure:
It’s a quite good LED High-Bay. Its surface, the structure, everywhere is fine. Such as uniformity soldering point, waterproof constructor and the solution for LED chips, each detail is representing the top craft of LED High-Bay.
Just there is one small problem.

The K Lock Nut for fixing and locking fixed mount will abrade the mount of housing by times of shift. After the abrasion, the Nut will get stuck and the fixed mount will not be moveable any more.
But for the high-bay, its location will be fixed as soon as get installed. It’s not a very big problem if lamp is correctly installed and application. And we cannot avoid the friction between metals as well.
Next time, we will share the detailed performance report of the LED High-Bay. See you soon.

We are 3rd party testing & inspection.
