Equal first, the lamp did not fit into the projector. Man has a small area, a piece cut out to fit. Leaving aside the red arrow in the photo. (At least on my model) Having compared the lights, it looks quite reasonable. The original lamp from Epson has only 881 hours on hold. (Was not the first usage) and also made in China! The luminosity is in my view comparable to the original. I can also find no yellow, red -or other color difference. For the price of 77.88 you can not go wrong. The original cost over three times! The first 10 hours. It is already in use. Should they give up before 1000 hrs. The spirit I'll write it down here.
