Easy to install, not really notice and the packaging does not really trust (it looked a bit light level protection) but the lamp works very well and the rendering of the image and colors are similar to original lamp. There was just one problem: despite the new lamp, the projector pointed at every start that the lamp should be changed. I think he senses that this is not an Epson but it works. Another thing that has perhaps nothing to do, the projector is increasing noise level ventilation so I wonder if this lamp does not heat a little more than the original. NB: it's nine months we use it daily (looking at the Tv) and RAS.
