I buy this lamp to replace the one in my ep719 projector , follow the instruction that come with the bulb , and it blow up my projector . I think maybe I get a defective lamp , but the other reviewer that have the same thing happen make I think these be just junk . Stay away ! although I do get a refund for the bulb itself , neither Amazon or the seller offer to replace or fix my projector . for try to save $ 30 , I lose hundred !
