I want to use smartmusic in my class this year and I want to use a projector.  How many lumens do I need for the picture to look decent in a lighted classroom?  I was thinking somewhere around 3000 but I don't want to buy a projector and that not be enough.  Anyone else using a projector with any luck?
 
Thanks,
Mike

This depends entirely on how large you wish the projected image to be: the bigger your desired image, the more lumens you'll require - remember the inverse square law applies to projectors just as any other light/sound/radiation source!
