A: This uses a 280W UHE lamp.
A: We bought the Epson 1440 for it had 4400 lumens but we also bought and Elite Ambient Light Rejecting(ALR) screen. Our living room is very bright and even with the special ALR screen we do loose some of the clarity and the picture fades. So with only a brick wall with lights on I would say that it could be done but your clarity would not be great. But to watch possibly a 110" screen(assuming that the brick wall is that big) would be awesome and fun to share with a group of people outside.
Q: Will this unit connect to my laptop by wifi?
A: This item does not connect wirelessly.
A: Nope, you have to adjust the image size in the menu settings
Q: How long is the power cord?
A: I'm just taking it out of the box and it's about 5 feet long.
Q: Why is this advertised as "home" projector.
A: The home Cinema projector has a faster refresh rate than a business-type projector thereby streaming movies you don't get a jerky motion
