I must have been asleep at the wheel, for I was unaware that Leef is selling Surefire C-compatible (at both ends!) bodies, in four lengths, at Lighthound. I thought that Leef had abandoned the call for C-C bodies and was making only bodies with M heads.

Has anyone tried the Lumens Factory HO-4 (3.7V, 150 lumens, 1.8 amps) in a Leef 18500 body?

I've always wanted a keyring light that was bright AND incandescent. Sure, a 18500 body is on the thick side, but its output would humiliate the wimpy 1XAA, 2xAA, 1AAA, and 2AAA options (like the Underwater Kinetics keyring lights). (It might even silence the Cree crowd over in LEDs.) Even the 1x123A incans from Pentagonlight, Digilight, and others are rated at just 40 lumens...and they can't use a rechargeable cell.

Me wants....

Interesting idea. I just saw these bodies as well and plan on purchasing one myself. I plan on grabbing a 2x18650 body to put my KT2 turbohead on, and run the MN20 and MN21 in it!! I can't wait.....:rock:

I've got an HA 1x18500 and the BK 2x18650 on the way. I intend to run the Litemania cree drop in in the 18500 body, and my MN16 in a kt2 head with the 2x18650.

15mm more for sooo much more capacity tho.. ~1500mAh to 2600mAh. But it would make a neat small incan. I much prefer the WE 3.7V LA to the LF HO-4 btw.

I would have liked to get a 1x18650 as well, either to run my KL3, or with a WE 3.7v.

But they are a bit pricey, and I have other priorities that have to come before flashlights right now:mecry:

Paul, yes, Pila's work. I'm running 600P's in mine. They are snug, but not tight. They will slide out with a little "flip" of the wrist, but don't fall out, at least mine don't.

I have the Milkyspit version, but i believe they are all the same production run.

Re: 150-(make that 175) lumen hotwire on a keyring (Leef)?

Yes! a 1400mAh 150A cell or 300P cell should drive that 2-amp lamp for about
35 minutes at slightly below its 190-lumen rating.

Paul, possibly a very dumb question... but where does one get the bulbs you guys have mentioned?

Lumens Factory EO-4 (3.7V, 190 lumens, 2 amps)
Lumens Factory HO-4 (3.7V, 150 lumens, 1.8 amps)

Granted I'm mainly an LED guy, but having a hotwire of that brightness driven on a single 18500 cell is pretty nifty. :naughty:

I got a 2x18650 and a 2x18500 C:C Leef bodies. The quality is very good. I like the all round checkered body style like the original Surefire bodies.

They both power my P91. (I have a LF D26 EO-9 on the way to try out).
I like being able to run my P91 reliably in a 9P form factor. The 18500's have a definate advantage over the 17500's and allow the P91 to be used with no double clicking.

PS...I now have an HA III Nat 9P, an item you can't buy from Surefire!

What kind of run time do you get on that set up? I'm looking at getting a 2x18500 and doing the same thing you are.

Hi, Guys,

The LF D26 EO-4 actually draws 2.35A at 3.7V, the runtime listed in the specification table is using Pila 600P. When it is operated using AW's 17670 or 18650 rechargeable batteries, the runtime would be shorter.

I now have the Lumens Factory EO-4 (3.7V, 190 lumens which equates to 125 Surefire lumens). I have one in a Leef 1 X 18500 body and another in a Leef 1 X 18650 body. Both are impressive lights.

Nah! For about $15 more, I'd rather get a spanking new E2E HA3 :laughing:

Fair comment. But think about the E2E with a Lumens Factory EO-E2R which gives 100 lumens instead of the standard 60 lumens when fitted with two of AW's R123As.

You must be the first Earthling to use such a bright lamp in a body as short a body as the Leef 1x18500. Do you carry it everyday? If so, how?
