Projection capacity:
Recently, I was in charge of setting up some technical equipment for showing images and presentations on a screen using projectors. We quickly found out that the required brightness needed a twin set of very advanced and powerful projectors. The guy how delivered the system, said something about ANSI Lumen being way off in comparison to what's required if you need something that gives a readable image under day light conditions.

Here are a couple of links to existing (portable) projectors on the market. The best I've found yet, is 1400 ANSI Lumen Brightness.

Will superbright LEDs give better performance? Any technicals out there able to put some figures on the thread?

The existing range of projectors are portable -but only just so. Since they use traditional light sources, they get warm, need cooling fans, and are subsequently heavy and bulky. I can't see how they can get substantially much better either.

If 'reversed VRD' (i.e. projecting on a wall) can cope with this, there are new gold mines to be found at MVIS.
