Oh, I'm such the wild card...more like, thinking out of the box, dreaming...kind of like js(where is js anyway?), but just that way after consuming mass quantities of drugs (do not try this at home, I'm a professional /ubbthreads/images/graemlins/smile.gif ).
1st, well the 'JA Special' has the 500lumens Stinger covered /ubbthreads/images/graemlins/smile.gif.
So that leaves the E2e size, me likey, me likey (really, I should wait until I'm coherent before doing these knee-jerk free thinking posts). I feel a high-five comin' on.
So with the E2e (didn't I mention this before?) we need to define bulb wants/needs, voltage, then appropriate power supply. I vote for the Carley 1499, cause it's T1.5 size, 385lumens, very high efficiency, not too much current draw at 2a, nice white and fleeting like a shining shooting star, and will give me that 1/2 way decent narrow beam I desire from a smaller head/reflector. You have not mentioned head/reflector size, bigger or optional turbohead is OK on the 500lm model, but we are intentionally limiting head/reflector size on the small form factor, yes?
Ok, we HAVE to consider thermal considerations in the small form factor. Carley 1499 is ~13w, so I propose dual purpose outputs. SF 10xLite, sort of. Now how do we incorporate 90 lumens Carley 888 at 0.7a and 3.7v, into this EDC? Both are T1.5 so can we put them both into the same head? Is there a way to mount them to rotate into the reflector for perfect filament centering in the same parabolic reflector? 90lumens low output for all the reasons other say 90 is enough, then short duration 385 lumens for when you need punch! One set of 10430 at 3.7v, Li-Ion of course like Doug S's 14430 smallest (YET) form factor LED. How many can be used parallel and series stack?. 3.7v twice for 7.4 to run the 1499,
Well, Ginny said he wanted to raise the bar correct? So I leave it to him to figure out how to do that in a E2E form factor. Would be nice if it could be regulated too, but 7.4v nominal for 2x Li-Ion doesn't provide high enough voltage for the smaller 2a limited SMD LVR from Willie Hunt correct?
Oh yeah, can you hurry up and finish this new light before next May? See, there's the 'JA Special' I need for previously explained reasons. Then there is this dual output E2e I need for...umm. Well, there's this HK born, very bilingual hottie that works at the local Dim Sum restaurant, and she graduates from university soon. Cantonese you know, skinny, like thinner and smaller than even Michelle Kwan! (Ok, Ginseng she's not jailbait either, went to England for HS, being in the LA area for almost 4years now, so she's almost JA age...almost "Old!" according to Jessica Simpson /ubbthreads/images/graemlins/wink.gif. Such lovely little hands...a dual output E2e form factor would work perfectly for her. Ok, do we need Doug S's or some other's expertise to get this Li-Ion version done(it has to be safe and foolproof for a n00b, 10430's are too small to do much damage if they fail correct, like her Li-Ion cell phone battery can't do as much damage)?
Well Ginny said it was his thread, that it was implied HID was out (hmm, I wonder who was the inspiration for him to use that disclaimer?), but he didn't initially say cell chemistry was not on the table. Surely js & Ginny could see this thought process coming from my reviews of the 8AA-2D adapters /ubbthreads/images/graemlins/grin.gif.
