KL3 + G2Z body

I don't know why anyone would want to do this to their brand new Surefire Nitrolon G2Z, but the KL3 Luxeon head fits it, and I believe the O-ring engages properly as well. So if all you have is a G2Z, you can convert it to LED by using the KL3 head. It looks a bit *****, but it does work, and you end up with a lightweight light (relative to the KL3+M2 combo) with all the existing benefits of the KL3.

I don't believe heat will become an issue because the KL3 head by itself is massive and well-endowed with heat dissipating fins. I'll let this Darwinesque hybrid run for awhile and see if it heats up any more than expected, though I honestly don't expect it to.

Talking about that massive KL3 head, why is it that it is twice as large in both diameter and length than the KL1? I can understand it being larger, diameter wise to fit larger bodies like the C2/M2, but why does it need to be twice as long as a KL1? Basically same circuitry, heat dissipation needs are about the same too I think. I wish the KL3 was smaller.

The threading is much deeper in this bezel, as far as I can tell. The original bezel/lamp assembly on my M2 has the same long threading that takes quite a bit of screwing in. My guess is if the KL3 were made any shorter, it would leave exposed threads on whatever you screwed it onto.

Thanks Craig, that makes sense in light of the fact that the M2/C2 is much heavier duty and all..

By the way, did PK say anything regarding the slightly higher light output of the KL3 (251K mcd vs 270K mcd)? With a greater heat sink, is this expected to be the norm?

I'll use the kl3 on my G2. Beauty is in the eye of the functionary Looking at the graphs the kl3 w 2x123 is stunning. Now to get a 3x123 body to fit.

Having celebrated my 39th(ha ha) birthday with PK and Kenshiro last night, here is some info on the KL3...

The reason the KL3 is as large as it is, is to accomodate the accessoreies that fit the standard M2. The other reason is that the LS is driven harder than in the KL1 the added size helps to dissapate the heat.

The KL3 does operate on the G2z body, but not recommeded as the nitrolon body does not disasppate heat as efficently as an aluminum body

Happy birthday Mr Ted Bear!!!

Mr Ted Bear, Happy Birthday! Is this your first 39th Birthday?

Craig's current readings are the same for both KL1 and KL3 at 270 mA. The battery life is basically equivalent. I thought the KL3 was a bit brighter not because it had a higher current consumption but just a little better cooling. Is this true?

Maybe somebody will give you a Surefire Beast.

As for the KL3/G2Z body, I did carefully test-run it for five or ten minutes, and the head was still comfortably warm - definitely well under 100°F. After that I just used it intermittently.

Happy Birthday Jeff!

Hey Craig, can you post a picture of the KL3 on the G2Z? I got a Z2 and can't wait to see what that combo will look like.
Thanks, Sam Adams

Happy Birthday Jeff. I consider 39 to be the gateway to either youthful maturity or mature youthfulness; I'm not sure which.

Has it been established whether running the KL-1 with three 123's continuously on (for hours)is safe?

39th unfortunately was several years ago.... but like wine, I'm getting better with age.

Funny you should question how a KL-1 operates continuiously... PK mentioned that he has had one on the test bench for the last few months using a constant current power supply.

<font size="2" face="Verdana, Arial">So... you're saying it might be safe to run it on batteries for a few hours?

What did you do, Jeff? Call me on your birthday? Did you have gifts?

Craig,

Slightly different question. Have you tried the KL3 on a G2R? Is that even a possiblity? Does the battery have enough juice to run it properly, and for how long?

Bright Scouter,

Please refer to Lux Luthor's comments two posts above, Craig will be out of action for a while (we're all praying he'll be back with us soon)

Sorry, I was gone camping this weekend and missed the whole thing. I feel like quite the buffoon now.

Add my prayers to everyone else's.

<font size="2" face="Verdana, Arial">Al (Size15s) mentioned on this Post that G2R will fit....

The KL3 will work on the following:
G2, G2R, G2Z
6P, 9P, 6R
C2, C3
D2, D3
M2
Z2, Z3 (also 6Z & 9Z & 7Z)

Jim,

I'm actually charging up my B65 as I type to do just that.
