Picked up a really cheap Scout Light recently. It is in really good shape and working condition but has an incandescant head/bulb (MN03 I was told) assembly. Think this makes it an M600B model?

The output is only 65 lumens from what I read on Surefire's site which seems fine but was wondering if upgrading to an LED head/bulb would be worthwhile. What I am looking for are cost effective options for upgrading to LED if so. I see if necessary I can get replacement MN03's for like $20.

I'm civ not LE/MIL and live in a pretty urbanized area so I dont see myself crawling through the bush taking on baddies. But I agree with many of the SME's that having a light on your longarm is worthwhile even if for just in case.

Thanks!
