The lighting is good, it is a white bright enough, as in the day (not yellow, for those seeking a cozy atmosphere ...) It illuminates much right away. For story, glass that covers the tube broke itself after 300 hours of operation (I'm sure I never have been bumped or dropped because I was very careful). He began to crack and pieces have altogether detached. I noticed it because one of the two bulbs that I installed started flashing alone. The glass was broken in places, cracked others. And the other lamp is also cracked. So I removed the two bulbs with security !! Otherwise, the level of commercial service, the seller would not hear because the case is not guaranteed ... And, obviously, the sympathetic tone of their response either ... Yet I do not think the assaulting in my email. I fear simply explaining the circumstances ... 300 hours of operation for a reported 8000 hour life ... Find the error!
