Ive got a SF G2 and want to go LED.. Maybe...

What are you buying when you buy a flashlight? A tube, which costs a buck or three, a tailcap with a switch built into it, which costs a few bucks -- and the LED (and voltage step-up circuitry, in some flashlights).

If that's all you think a flashlight can be, then you haven't handled a SureFire yet. :yawn:

I've had my share of surefires, and none of them have been that special....now when we talk about HDS/Ra....thats a whole nother level

I just cant see spending $55 on an LED module for a $30 light..

i know....but a comparably priced surefire doesn't do half as much, but to each his own you know?

I respectfully disagree. I didn't know about them before, but if I ever get the cash, I'll definitely pick one up to compare against my SF lineup.

Personally, I love the dual outputs of my E1B and E2DL. I clip it up on something on low to read, and if I ever need a good piercing beam it covers that as well. Build construction is also a quality that I value. SureFire lights are exacting in their build quality and construction. O-ring sealed, Pyrex class, hard coatings, the whole thing is phenomenal.

I like Fenix flashlights ... made in China but excellent bang for the buck

I have this thing about MIC. It's almost like a gamble. On one hand you could end up with some nice stuff, Byrds for example, and on the other hand you could end up with those terrible Sigg knockoffs they make. I don't like flipping coins when I'm putting money down on something that I am going to depend heavily on.

Powerful LEDs do get hot; in fact they get hotter than a xenon bulb of similar output. (Efficiency is about the same but an incandescent radiates some of its wasted energy as infrared; a LED doesn't.) Heat sinking is a big issue with powerful LEDs.

I though thats why LED's were so efficient, was because there was not as much heat as an output...
 
There isn't as much, with new ones, but it's still a different sort. LED waste heat is at the circuit level, not radiated. 100% of the waste heat goes to the heatsink and hopefully body of the light, as opposed to incandecents where it's turned into infrared radiation. This is why very high power LED's "feel" hotter in the hand. At lower current levels (around 1-2 watts) power LEDs are at their most efficient, and produce the least amount of heat per lumen. The M60L and LL are run around this power level and can be safely used in a plastic body indefinately. At higher power like you'll see on 90% of modern lights, the efficiency drops a good deal and you get more heat output. The thing is that current generation LED's are only around 30% efficient, incandecents around 10-15%, and previous generation leds (luxeon 3/5) only a hair better than incans.
