this is why I fought sooo hard to make an all solid state single mode projector. The pencil thin 1mm beam is just sooo much more satisfying on my wall for graphics. I don't do beams so cant say. However my divergence is very low as single mode and the beam is very tight so my power density is very very high. This means my beams are probably as bright as 1w even though I only have 350mw in the beam. In fact it is almost as bright as my 1.5w larger projector.
