I thought this lamp was a "super bright" cool white color. No, that is not so. It has a "medium to low" brightness and produces a warm white light. It's also advertised as a "backup lamp" (external lamp) but if you look at the back of the lamp it says "for internal use only". Due to the high LED count, the pompous product description and the higher price, I thought I'd get what I needed - disappointed. Excuse me.
