Surefire LX2 Pics, Beamshots & Info

I'd be willing to bet someone has already bored out the tube to accept a 17670. All you need is some 100 grit sandpaper, a 1/2" diameter dowel rod, some tape, a drill and a little patience.

the L2 is in the shape of the A2 in terms of body cavity...I have yet to see someone successfully stuff a 17670 down its belly :ohgeez:
 
Sean, thank you for the excellent review. Your pictures are excellent btw.

The difference in output between this and the E2DL is huge to my eye.

Impressive!
 
Got mine today!
It's brighter than my E2DL, and..
wow! 9280 lux at 1 meter, this is crazy. I like LX2 :twothumbs
 
Wow i must say i lost interest in this light,however looking at those beamshots it's evident that this light is easily putting out 260+ lumens.

MrGman tested his E2DL at just over 200 lumens and this light looks much brighter. If this light will have the same output with a 17670 cell i'll be all over it,if not i won't touch it.
 
The original SF L2 Lux V, was overdriven on high, with mA's to LED about 880 or more, higher than the KL4 which was driven about 700mA's to LED, or so. Maybe SF is doing this with the LX2, running the Cree at 1amp+ to the LED, to provide that max output, but with maybe a sloping output. I may be wrong as I have not seen a runtime graph of the LX2. The L2 was sort of the special Lux V light in its day and its runtime was no where as flat as the KL4. Just thinking out loud here, so don't take offence.

Great Chao.:twothumbs Can we expect some of your wonderful runtime graphs in the future?
 
I wonder why its only single mode on the regular E2E bodies:shrug:

Oh, as you probably know I was thinking more along the lines of an E2E. Sorry. 😱

oh, hmm🙂

Fortunately now that the L2's head is no longer "dumb" I suppose there will be a third party body that's 17670/18650 compatible assuming of course those buck circuits can handle the 30% lower voltage of a Li-ion

better yet, anyone stuffed a 17670 down the head end?

Runtime test added to the original post.
1H 25M in regulation, 2H 2M to 50%. Held in hand to keep cool.


It's funny how things quickly advance. 200+ lumens running in regulation for 1 hr and 25m would have been totally unheard of just last year!

LOL, I still remember when I got my first HDS B42XRGT....I was like "Wow, this is bright" :crackup:


:twothumbs Thanks for taking the time to do the runtime testing :twothumbs
 
So much for my thoughts on the runtime being steep. Very interesting that they got what they did. What is current draw at tail?

Nice review! Thanks for posting it...
Man, Surefire TIR optics rules! I love my E1B and L1...

Those LX2 beamshots are awesome! :party:
 
Run time test @ ~200 lumens. Light held to keep cool. 2 hours & 2 minutes to 50% (Panasonic CR123A exp: 2018):
[/B](hours) : (minutes)-(light output)
00:00-135
01:00-135
01:20-135
01:23-135
01:24-134
01:25-133 (light drops out of regulation)
01:30-127
01:35-122
01:40-118
01:45-112
01:50-100
01:55-87
02:00-72
02:01-69
02:02-66 (~50% output @ 2 hours & 2 minutes)
02:03-63
02:04-60
02:05-57 (ended test)



Thanks for the runtime test :twothumbs
 
Thanks for current draw results. That is good. Must be using some steller LED's. How is heat over time? You held it throughout test? Never got hot like a KL4?
