Pete thanks for pointing that out. Yes is a 4D with 87mm extention.
Tailcap only few mm short of touching last battery. Use copper braid, 1/2 inch wide stuff folded once. Lots of room around battery so leave cardboard on the cells.
After 4-5 min intermitten run head was hot, not too hot to touch but getting there. Body warm down to switch. and took 15 min to cool off.
Reluctant to say but think it is funny. One way I "test" my mods lumens, more lumens produce more heat, and don't do this at home folks, place palm of my hand over window and turn on, start counting 1 one thousand, 2 one thousand... Did not even get the switch fully depressed lacking on with half of one said I jerked my hand away and keep ice on it for 20min.
Northern Lights tailcap mod is so low resistance lights are noticable brighter so am converting all my lights over.
A123s are physically lighter weight and wonderful in 3D, or 4C feels like carrying no battery.
Emolis as Lux pointed out use Li Po charging program and 3.3v nominal, 4.2v fresh charge. Emoli shrink the form fact so much.
Pete you think 5 emoli instead of 6 A123 run IRC50? Could lose the extention, think 5 would fit in 6D. Emolis do sag some 20.0vbat 18.2vbulb with load of 64458. Think will try a 50w tonight with fresh pak.
Both are "flahlight friendly" at the power levels we use and rates of charging faster for both than NI Mh , and older Li chemistry. A123 Charge at 4C and up to 60A discharge , Emoli Charge 3C and up to30A discharge. Like those 15min charges.
Hi Jim (and Lux)
I've got a couple of 64458s and some E-Molis coming soon and this is all really very interesting.
One thing - I think you may be meaning a Mag4D +87mm for your 5x E-Molis ? Also are you using a no/modified-short-spring tailcap ?
I have recently been trying out an IRC50 with 6xA123 cells in a 6D+37mm - (can't wait for more IRC65s to arrive to try them ! ! !)
The IRC50 6xA123 runs Vbulb 19.7V @5.2A (at least initially) and is really quite a bit brighter than an IRC50 run from 5x AW-CLions (18.8V @5.1A)
AWR-Hotrater gives :
IRC50 as about 5400 B-Lumens and 3500 T-Lumens @Just over 100W.
IRC65 as about 7200 B-Lumens and 4600 T-Lumens @Just over 130W
The 6x A123 should also be quite happy to drive the IRC65 while that would be a bit much for the CLions !
Don't know quite where this would put the IRC bulbs in The Lux List ?
:candle:
Cheers Pete
