As pointed out it's a great little light for small tasks, but unless what you're doing is directly right in front of you you're not going to be that much light out of it.

I'm pretty sure at this point anything like the Streamlight mini-Sidewinder, Energizer Hardcase helmet light, and others are going to offer more lumens.

The nice thing is that it already has several different adapter mounts (Tango Down for mounting on M1913 and the ballcap mount) and the standard SF MOLLE adapter.

A big plus I found is that even though it's not that bright it's significantly lighter and smaller than any other 1 cell 3V helmet light.
