Just got the IMR 9 D26!!!!!!!!!!!!!!

[bigchelis]

I got home from work to find a IMR 9 D26 (500 Lumen) for my Surefire 6P. I dropped in two 16340 (not AW's) The light barely had any power. I read the post here about tapping it on/off a couple times to trick the battery.

Then it went on. Wow. Talk about power. The cells began to dim at around 11 minutes and I stopped running it at that point. I was hot; amost too hot to handle. The sucker is bright and has good spill.
*Next I will be running it in a 2 18650 AW set-up. 6P bored with 18650 extention.
In my P7 LED I wrap it in aluminum foil to help with the heat.

What can I do to help with the heat from this heat issue??????

Be sure to use a body that dissipates heat well. That's the best solution I could think of right now.

That or you can get a number of IMR-9's and put them in three different bodies (effectively making three IMR-9 lights). When one gets too hot, just exchange it for a cool one while the hot one can chill out!

I was planning on doing this with the EO-9 and three of my Pila GL3's.:naughty:

Also be aware that unless your 16340s are LiMn/IMR, you are destroying your cells, and may be turning them into a fire hazard. That protection circuit that you had to click several times to fool is there for a reason. Some AW IMR 16340s would be much safer, and probably a lot brighter too.

However, any chemistry 18650s should be fine, because the bigger cells can handle the current draw.

I had two AW16340's, but now I could only find one in my home

So, I was using the trustfire. I did put in an order for 2 more at lighthound to keep things safe.

do you have a P91 to compare it to? I would really appreciate pictures if you do

I'm assuming that when you bought the IMR-9 lamp, you've read and understood all the WARNINGS regarding the safety issues when using the IMR-9:

***This Product is Designed for use with IMR(LiMN) Batteries ONLY***

Heat Warning: This lamp produces EXCESSIVE HEAT and should not be operated continously for over 10 minutes.

I did only run it for 10 minutes, but it gets really hot. At the time I didn't have AW16340's so instead I am now waiting for my AW18650's to use in a 6P bored with extention.

I think the bigger cells will help with runtime and the aw cells will hold the amp draw safely. I will turn it off every 5minutes for now.

I guess my question was can incan lamps be wrapped in aluminum to help with the heat like a P7 LED?????

I think you're missing what people are saying about the batteries (maybe I'm wrong).

You can't use the AW black label rechargable cells. You have to use the AW red IMR cells. Although both are rechargable, they are NOT one and the same.

My apologies I meant the red IMR 18650's. I had purchased AW IMR 16340'a to run the P7, but now I rather have AW IMR 18650's for the incan.

I know it's hard to resist being an authority on the aspect of the original post that you do know something about, but how about someone being useful, and answering the guys question about the heatsinking.

 

[GreyShark]

If it's heat you're worried about there's two things I'd try. One is replacing the Z44 bezel with an M2 bezel. The M2 has a lot more metal to absorb the heat and more surface area to radiate it. I have an LU60A black hard anodized M2 bezel on a 6P and the color match is good enough for me. Some M2 bezels were made in type II black anodizing but you'll have to find a used one at this point. The other is cord wrapping the handle to insulate yourself from the heat. Or wear a glove.

Just looking out for you bro! lol

I don't know too much about the heatsinking, other than that you shouldn't run it for more than a few minutes at a time.

I'm running mine in a Surefire C2, and for the first time ever I'll be bringing it to work tonight. (I'll still keep the Strion in my duty bag, and the E1B clipped to my vest in case I need a light for more than a few minutes at a time). Should be interesting for use on traffic stops -- lol, 500 lumens at close range through a car window, hahaha, this is going to be great. I only wish I could take pics.

Yes it can, but only by running the 18650 extension AND the foil.

By only using just foil but no extension: you would not be prolonging the runtime of the light because using foil helps to increase the contact area between the lamp and flashlight body, which helps to transfer the heat faster to the body, but because the amount of metal in the flashlight body remains the same as without the foil, the amount of heat dissipated from the lamp remains the same.

End result of using just foil around the lamp: the flashlight body will heat up quicker, but it will not be running cooler than without the foil because the size of the heat sink remains the same.

End result of using both foil + extension: better heat transfer to the flashlight body and run cooler for longer because the overall surface area and amount of metal to act as a heat sink has increased.

Good luck and always put your personal safety first!!!

What's the current draw of this beast? I can't find it on the site....

I would rather take a C3 to accomodate larger batteries or, as you plan, use a host that will take 2X 18650s. These will always be able to fire this hot thing up, as the maximum of 2C is somewhere around 4 to 5 amps. This should really do

I'm wanting the 700 Lumen beast for my M90 rattlesnake! This one draws 2.2 Amps, so 18500's will power it safely for about half an hour.

With my C3 I'll have an experiment the other way: let's see what an energy-saving lamp from LF will do. When I remember right, it draws 0.85 Amps, this will comfortably be enough for an hour runtime using 2X AW 17500s with 1100mAh.

I'm still not 100% clear on which batteries are being used to drive this IMR-9 here, but the original post describes a scenario where the cells are being run for a constant 11 minutes to dimming on cells that had to be "tapped" on to run. This means that LiCo cells were run through a near full discharge at a ~6C rate, that's TRIPLE their maximum safe discharge rating.

The nonchalant-ness with which you describe doing this scares me. I would put a mark on those cells indicating that they have been abused and have a higher risk of explosion in future cycling, especially charging.

Yes,
Initially all I had was 16340 ebay protected versions, but I put those aside and now run only IMR 16340 and IMR 18650 for the turbo head or IMR 9 D26 incan.

The cheaper trustfire batteries will only see LED R2 duty now and the ones I used for this set-up initially 16340's are retired.

Forgive my ignorance, but what does "AW" and "IMR" stand for.

I am looking to get started with rechargable Lithiums.

Thanks for the help!

AW is the name of the person on this site who sells the AW and IMR Cells.

The AW line of rechargeable cells offer quality and protected li-on cells.
AW also offers un-protected cells he calls IMR cells. These IMR cells can handle the higher currents better.

I do not know what AW means or what IMR means, but I just assume it means super quality stuff because that is all I keep getting from him.

I picked up a IMR-9 a couple of months ago. It is significantly brighter than a EO-9 (both on IMR 18650s in a FM body), but is more floody.

I currently run in the FM body a D26 Sunlight with a WA 1111. The beam is a bit tighter with more output.
