I wouldn't get my expectations too high. Unless someone has developed a powerful light souce that generates no heat, this thing will be fairly useless. At 50" in a totally dark room (I'm talking pitch black) it would take several hundred lumens to be more than a worthless novelty. It obviously has no real ability to to handle serious heat so it's almost certainly LED based putting in just upwind of an oversized keychain flashlight.
I just found the specs = 10 lumens - it's a bigger joke than I thought. The first projectors thought to be useful were 600 and the current models are above 1600 min. Keychain flashlight is not too far off the mark.
