Incan with rechargable cells?

[chiphead]

Is anyone using lithium rechargable cell to drive an incan. I can't seem to find a bulb that can handle a them.

Which brand/model of light are you talking about? There are many many rechargeable bulb options but they all depend on what you're putting them into. Lighthound sells LumensFactory bulbs, many of which are rated for use with rechargeables.

A sf P90 easily handles a pair of rechargeable lithiums.

Depends on what bulb/light you are trying to drive with a pair of LiIon
I have 3 Incans on my bedside table (M3 M4 M6) and all are running lithium ion cells with appropriate lamp assembly's (m3 with 2x17500 and LF HO-M3, M4 with 2x17670 and LF HO-M3T and M6 with 2x18650 in special carrier with LF IMR-M3T bulb)
It can easily be done, providing you are running an 9v bulb for a pair of lithium ion cells or a "3.7v" lamp for single cells (not a 3v lamp, the voltage will start up around 4.2v)
And providing you aren't drawing too much current from the cells.
I prefer to use AW brand protected cells, they have worked well for me so far

If you have a search there is a thread that lists suitable bulb/cell combinations, and expected output/runtime for most models of surefire Incan and a few other manufacturers lights, I can't remember what the thread is called though

any 9V D26/D36 size lamp assemblies (SF, Lumens Factory, others) can be driven by 2xli-ions, provided they can take the current draw. Wolf Eyes and Solarforce are among the good hosts for these lamps.

I was going to take Solarforce L2 body and turn it into something more than the 60 lumens of my 6P. Just trying to keep the incan relevent in the digital age.

Hi, chiphead

Here's a fantastic resource for most combinations that could work for you: http://www.candlepowerforums.com/vb/showthread.php?161536-MDs-Lithium-Ion-gt-Incandescent-guide-compatability-comparison-chart

All of my incandescent lights (except a G2 with P61) are run on lithium ion batteries. Google each light you are interested in and look for compatible batteries. I made a giant list and your choices are many. Here is a very short list:
2x Li-Ions:
· MN15
· MN16
· MN20
· MN21
· Osram 64250
· WA 1111
· Philips 5761
HO-M3T (380 lm)
EO-M3T (320 lm) IMR-9 (500 lm) IMR-M3T (700 lm) IMR-M3 500 lm)
N62
P90
3x Li-Ions:
MN60* (3 AW RCR 123 with 1 dummy cell in M4.) Note: Low runtime!
· MN61 (I’ve used 3 X 16340 IMR + spacer in M4. Very bright!* jr)
· HO-M6R (700 lm) IMR-M6 (1,000 lm) {3 X 16340 is okay) (M6)
· WA 1185 (No IMR cells for 1185 because of instaflash) (M6)
12V Chinese lamp assembly in G3 with 3 RCR 123
Interesting note on the G2: I have a G2 with a Chinese 7.4 bulb and on rechargeable batteries it is noticeably brighter than the P61 with Surefire batteries!

I use strictly B65's, and pretty much run whatever 6-Volt incan lamp I want (P60/P61/N1, not including the non-SF bulbs), plus it works with a myriad of LED drop-ins as well. The ONLY disadvantage the B65 has over other R/C's is size. Other than that, they are safer, no extra "boring" costs, fewer cells to carry around, last longer, and the chargers are pre-built for home or auto charging. I can charge them once a month, and have reliable spares, etc.

DealExtreme sells a Xenon drop-in which runs well on 3.7v cells, I use it on a single 18650 sometimes just for the fun of it. It draws 2A regulated on high and is $3!

😕 😕 😕 regulated Xenon drop-in for $3 ??? 😕 😕 😕

I run one of my SF M6's on 3x 17670's.

Yeah, sku. 3246. (EDIT: Sorry for the typo.)

It isn't truly buck/boost regulated but seems to only drop from 2.1A to 2.0A after running for almost an hour. I haven't done a full discharge test though, maybe it is just relatively flat discharge voltage on my 18650's. I ordered two just out of curiosity and have been very surprised, in a good way of course!

 

[chiphead]

DealExtreme huh? Ok, I'll check them out!

3246.

They're decent lamps, especially for the price. (I had the 7.4v version)

100% agree but not regulated of any kind.

 

[RedForest UK]

Yeah sorry, I'm not really familiar with current discharge on incans. The drop-in I'm using at the moment draws;

2.15A at 4.2v,
2.10A at 4.1v
2.05A at 4.0v
2.00A at 3.7v

I haven't measured any lower voltage/current than that as I recharge when I can. I had assumed that due to such low input current drop across the discharge it had some sort of basic regulation, but I guess not..

I'm still very pleased with it for $3 though, it puts out well over 100 lumens and as it runs on 18650 it will go for 70mins+ with no real cost as I can just recharge again.

Redforest,

Is the bulb in the 3246 from dealextreme a bi-pin or perhaps a pr base? Can it be removed from the reflector? Anyone else feel free to answer. Thanks.

It's a bonded lamp/reflector module similar to P60 but works with 3.7 volt (single li-ion cell).

Can it be removed from the reflector?

No.

 

[Sci Fii]

Thank you, fivemega.
