Great appliance

We put it in the engine room of a 65’ motor yacht to replace a failed fluorescent. The only problem is that my engineer wants to replace all aboard with this fixture. The light is brilliant, the illumination even and installation was a cinch.

Great shop lights - perfect brightness and temp

Great customer support and fast shipping. High quality lights. I like that the 2' and 4' lights match perfectly so that I can fill the room with lights where I have space. I've replaced nearly every light in my home with superbrightled lights.
