There is no chance in the world I would even consider this for any commercial use. Read the review on this one. The projector is DIM, DIM, DIM, DIM!!!

400 lumens, real world, is about enough light to work on a 8 square foot screen. That's about a 52" diagonal. Or, you could buy a flat panel display, of similar size, for about the same amount of money.

Conference room projectors don't use LEDs, they use laser light sources, and they tend to be a good deal pricier for the design of the solid state light engine. It's rarely a good call to go this route, and I would stick with an Epson LCD projector with a 5,000+ hour lamp life and $100 replacement lamps instead. Think 3,000-4,000 lumens or more for quality results. For 3D, the manual should recommend 3D glasses which will work. It is true though that DLP will work with more 3D glasses using standard DLP Link glasses with their 3D. Be aware that many computer based 3D systems actually use RF emitters and specific glasses for their 3D cards, which have nothing to do with the projector, so this can be hit or miss depending on the source and graphics card in use.
