50mW green - power output with star cap

[montymintypie]

I've got the 50mW O-like 6-in-1 greenie in the post, and I was wondering, what's the power output like when there's a star cap on it?

Eg, with the star cap off there's one beam that's 50mW, but with the star cap there's about 50 beams - somehow I don't think that they'll be 1mW each.

Anyone with an LPM tested this?
