thanxPtolemy....welcome to CPF! I cannot think of any others besides the 18650 either. Good luck on your search. Maybe the TK40 on High (not turbo) Or one of the other MCE 2x18650 lights on med. No other guesses for now.
nonoYou could conceivably fit C or D cells in a light and still be under 50mm in diameter, but there aren't a whole lot of options as far as C and D hosts go.
Something with 2 18650s would probably have the best runtime, but if they are end to end the light may be too long for your liking.
It shouldn't be too hard to put one together.
For a recent bin XR-E or SSC P4, 150 lumens requires ~500-600 mA, or somewhere in the neighborhood of 2W. Accounting for converter losses, five hours of runtime will require roughly 12Wh. So if you can find a P60 drop-in that runs on 7.4V and doesn't drive the LED too hard, 2x 18650 or 26500 should easily get you 5+ hours.
Any decent C-cell based LED light can do it. It's nothing special.
For example:
#1
- SureFire KT2, FM 3xC body, AW Tower, 4P MC-E K-bin, GD1000
- 0.844A current draw at the tail
- 5000mAh NiMH cells
Calculated run time of 5000/0.844=5.9hr
Calculated output, 280-330 emitter lumens
#2
- 4C Maglite, P7 DSWOI, SOB1000, KD OP reflector
- 0.84A current draw at the tail
- 5000 mAh NiMH cells
Same calculated run time as above
Calculated output, 340-380 emitter lumens
3D Mag + Malkoff Drop-In Module for 2-3 D-Cell to fit Mag-Lite + 3x NiMH D cells
240 lumens for ~10 hours.
Or, similar set-up in 3C Mag for a little under half the runtime.
i'll check them out for sure.The PEAK LED SOLUTIONS LEO lights are available in a range of higher power configurations with an assortment of interchangeable battery tubes. Your specifications should be easy to meet.
i spent good hour last night looking at maglite mods. seems most of them are designed for max power.+1 for a maglite upgrade
i spent good hour last night looking at maglite mods. seems most of them are designed for max power.
i am looking for the balance of good output and very good runtime. obviously biggest issue is to keep it cool.
are there mods made like this that fit my spec? 200-250 lumens, and long runtime? made from 5c, 5d,6c bodies?
if you could provide some links, i'd appriciate it. i am kinda lost in all the replacement components
Mine doesn't rattle at all. I've never seen an Inova with battery issues. Their workmanship is flawless. In fact, when I sent a T3 for boring out in order to accept 17500's, the workshop guy told me that he never saw such precision before...
in layman terms: i need a 4c or 5c mag-lite body (for premade body - i think i seen 5d body), replace the guts with custom drop-in module supporting C or D NiMH cells, and change the emiter to high 3w one
right?
if so, could someone give some examples of the body i need, emiter i need, guts i need, to maximize burn time and to stay at least at 240lumens (higher the better but mini burn time 6 hrs, 10hrs sounds even better!) and use rechrable batteries

As I described before, I used a 4C Maglite, P7 DSWOI, SOB1000, and KD OP reflector. The SOB1000 underdrives the P7, resulting in a very cool-running, long-running Mag mod with 300+ lumen output.
PhotonFanatic in the Dealer's Corner on CPF MP now has DSVNI-bin P7s. Basically the same thing, slightly different tint. Order an SOB1000 from The Sandwich Shoppe. For a drop-in reflector, get the Kaidomain ProductID=5632 15mm opening orange peel reflector. It's more expensive than some other options that can also work with the Maglite, but it is a plug and play solution (no filing or other fitting work necessary). A 5C, 6C, or 5D Maglite will give you that much more run time (and size), compared to the 4C. Use any of the usual C or D Mag heat sinks from Litemania, H22A, Britelumens, etc. Add in wire, solder, thermal epoxy, and your time.
i guess i have to wait for premade solution to be available, however it seems like all the big boy's (the 6d /6c mag lites) aren't designed to run at 300lumens for 10 hrs but run at 3000 lumens for 30 min
