Question: If I built a 13-cell m*623, what lower-powered EDC bulbs could I use in it for EDC? I'd still want it bright - somewhere in the ROP high to Mag85 range, probably...

Any good bulbs that would be simple swaps, using the same power supply?

Thanks in advance for your help!

I never found a suitable bulb. Now that IMR26500 cells are available , they are my choice of cell for big hotwires over NiMh.
The combo that does work is 64458 and 64440. 64458 is really good on 5 cells at around 10Amps , 64440 lower output option at about 5 Amps.
Run times approx 12 minutes/25 minutes.
 
If you can use an 11 cell setup, a 62138 (like the USL) will provide 3000+ lumens while still allowing you to use many common 12V bulbs. You also get a nice axial filament.
 
that might work for me. am i correct in assuming that the axial filament makes for a nice thrower? i like the idea of a spotlight-like flashlight. i think it'll be useful for me, as well as "play well" at deer camp.

will the 62138 bulb start fires with that battery setup?

(i'm not afraid to admit that a large part of what i'm after is braggin' rights...)

thanks!

I've had very good success using a long life 2000 hour rated 12 volt 50 watt 64610 on packs using 13 Elite brand 2/3 A sized cells. They handle 18 volts without a softstart and up to 19 volts with a softstarter.

The ones I'm using at the moment are these Omnilux brand bulbs.

They pull about 5 amps at 18 volts. They do start fires but you need to crumple up the newsprint in such a way that there is as much black ink as possible showing in the spot you are going to aim the beam at. It takes between 10 and 15 seconds for ignition.

Similar to Osram 64440 but without the IRC technology.

Here's a thought. What if I packed a m@g host with 16 x 1.2v cells and rigged a switch that would let me run those cells in either 16s configuration or in 2p8s configuration? Could I then use those batteries and that switch to run a sort of "2 mode" light with a 64458s bulb (rated 12v, 90 watt, 4000 hours, which probably means it'll take a good amount of over-drivin'...)? Underdriven with the 2p8s, i imagine it'll be pretty yellow, which I think I'm ok with, as long as it's still usably bright. Would it be brighter than, say a 3-cell stock maglite underdriven like that?

So much to learn...

Thanks again for all your help!

You'll probably end up with a 50watt light with less output than a good 20 watt light. Sickly yellow beam too.
It seems like a very complex method to achieve what an AW Incan driver does much better.

So, this sounds like it might be what I'm after... What sort of host would I need to house 5xIMR26500? Will it fit in a stock 4D? If I used 5C, would I have to bore it out?

I know I'll need to replace the lens/window and the reflector, as well as grabbing a bipin adapter of some sort... What about the switch? I've seen references to "the switch mod," but I haven't found a thread that tells me how to do it... Also, can the 5 batteries be charged simultaneously? What kind of charger setup (or mod) would I need?

Thanks for all your help! Every time I swing by this site, I learn a little more. I finally feel like I'm getting there...

Thanks again!
