The projector is much brighter than our vivitec '1000 lumen' LED projector, but 5000 lumens is definitely not it. I have no way of measuring exactly, but in comparison with similar (but UHP lamps) products in this power class I would estimate 2000- 2500 ANSI lumens. In a bright daylight room, the colours only come out with a good screen. A challenge here is also the not so outstanding contrast: slightly darkened or with a good wall, however, the part is a real joy!

The lamp has 5000 lumens and with a 100" screen you can measure 1600 with a white picture.
