Very satsifait product at the reception: no difficulty for replacement. Proper functioning for 6 months but now the brightness dropped in one day: possibility of viewing in complete darkness but with a black spot in the center of the screen: is it the bulb or DLP? The symptom is different compared to the loss of the original light bulb that worked juqu time when the failure was frank. It is for this reason (probably) I note that only 3 *. Not able to honestly recommend this bulb ... Given the price of the bulb and the age of the DLP (9 years), I do not try to understand because nothing will cost me a quote as expensive as a new LCD TV. I decided to replace the TV.
