If you can name another light with that amount of output, with the intuitive convulsive interface able to get to high mode under stress without looking at the light, the option of a lower-output setting, with the solid Surefire build quality and product support, handy enough to keep with you 24/7, I'd love to hear about it.
Peak Logan generation 2 QTC with momentary switch, the 17500 body accepts AA, AAA, and any chemistry/voltage variation in those sizes, also available on 123 body size. Around 300 Lumens in high
Even more portable with the same characteristics Peak Eiger second gen QTC AAA also with momentary switch, but for tactical purposes, it might be too small, this is the light that is always with me, this light on Li-ion is 225 Lumens (which is great for a bombproof AAA).
I have a couple of Surefire L1 and i love it, but its bigger than the other 2 lights, and the tailcap while great, after too much work looses contacts inside on the PCB, there are 3 contacts soldered to the PCB, after a lot of use they start to break, The great Surefire guarantee replaces it quickly, but after it being discontinued i dont know how that will go, around 3-4 years ago they sent me a replacement and it was great, then a couple of years ago the other L1 had the same problem and i asked for a replacement, they responded me, and halfway through the communications i lost them, no reply yet, dont know what happened, will send another mail to see if they respond, also the rubber cap of the momentary button deteriorates faster because it endures a lot more pressure than a clicky.
Peaks are bombproof, i dare to say they are even more resilient than the Surefires i have, the only drawback is that the QTC can be a little less precise after a lot of use but i have found a couple of fixes that solve the problem and its better to have something that will still work good after a lot of use (you loose precision in levels between low and high, but high will always be there and the light will never fail to turn on), and its definitely better than having to wait for a replacement part.
But if you put both Surefire and Peak quality to compare with other lights they are both on the top tier of production lights.
One GOOD advice: buy through Oveready, they have the BEST service and post sale service i have ever had.
