“The lamp I received only worked for less than a minute. My projector began to over heat which caused the lamp from not functioning at all. After testing it a few times (with the same results) I used my old Optoma brand lamp just to make sure it wasn't the projector (and not the lamp). The old Optoma brand lamp worked well (its just nearing the rnd of its life). I would strongly suggest buying the real deal from a licensed Optoma dealer.”
