Are you looking at this as an indoor/outdoor projector or both? For outdoor, it looks pretty good. 3500 is plenty of lumens, 15,000:1 is excellent contrast. It will show a 16:9 image (native 16:10), so you're good there. For indoor, it may be really bright, even in eco mode, but it has memory settings, so you could set one for indoor and one for outdoor, cutting back the brightness when indoors. That's my 2 cents.
