Surefire LX2 Pics, Beamshots & Info

there's always the 14670

LOL

[mudman cj]

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.

Or unprotected 17650's, and monitor cell.

is it too soon for some runtime tests/graphs?

If I get time this weekend I may do a runtime test on high. We shall see.

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

[Patriot]

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!

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

Got mine today!
It's brighter than my E2DL, and..
wow! 9280 lux at 1 meter, this is crazy. I like LX2

[1996alnl]

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.

[Bullzeyebill]

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. Can we expect some of your wonderful runtime graphs in the future?

[Crenshaw]

now i reaaally want an Lx1

[Illum]

I wonder why its only single mode on the regular E2E bodies

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"


Thanks for taking the time to do the runtime testing

[Bullzeyebill]

So much for my thoughts on the runtime being steep. Very interesting that they got what they did. What is current draw at tail?

Bill

[Federal LG]

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

Those LX2 beamshots are awesome!

I got .776A on fairly fresh Surefire cells. That's a little better than my E2DL.

Thanks for the runtime test

[Bullzeyebill]

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?

It took a good ten minutes to get beyond warm. But even then it was not uncomfortable to hold. If you don't hold it, it gets pretty hot and then the brightness sags a bit. That's the main reason I held it. I wanted to draw as much heat away from the LED as I could to see how flat the brightness would be under those conditions.

Thanks for the review

From the Thread Starter Post:

Surefire LX2 LUMAMAX:
FEATURES

• Virtually indestructible LED...

Cons:
When you twist for constant on the tailcap is rubbing against the clip. It's not real bad because there is not knurling but it could wear the HA down over time.

Sean, I too was concerned about the possibility of wear of the Tailcap HA against the clip as the tailcap is rotated. I took a -210 Nitrile O-Ring from an assortment that I have and slid it onto the body and it rests where there is a small groove near the tail of the body. The O-Ring is thick enough to hold the clip away from the tailcap so there is no contact. The -210 ORing is 3/4" ID and made from 1/8" material. I ordered some GITD ORings from from Sigman to make the LX2 a little quicker to find and grab for those "bumps in the night".

[Litbobber]

Hi MikeF
Great idea can you show a pic if possible?

Thanks

[Sean]

I added a few more pics to the original post:

My clip just barely rests on the tailcap. And since the tailcap is round and the clip curves back on itself at the point it touches the clip there seems to be very little actual contact between the clip and the tailcap. I don't feel or hear any resistance when I turn the tailcap either. So I'm not all that worried about it. It's not nearly as bad as the Fenix T1, where the clip drug on the knurling. Another option is that you can just pry up slightly on the clip before you turn the tailcap.

Here is what mine looks like:

Can't believe this baby is soooo bright!

Does anyone know, what kind of LED is built in?

[Illum]

Titan T1A on high:

assuming your camera setting is consistent, then the T1A really needs some help

Can't believe this baby is soooo bright!

Does anyone know, what kind of LED is built in?

CREE, unknown bin, and most likely unknown tint because tint lottery is at work in surefire's lights

[Sean]

The Titan is singin' the blues.

[Marlinaholic]

Looks like I'll have to bend the clip a hair so it sits just above the cap a millimeter or so. Or I might just remove it, I don't think I'd use this light clipped to the bill of my cap anyway, and with that nice lanyard attachment, I really don't need a clip for my pocket. Can't wait to for mine to get here
