Has this been done?

Ok so i was thinking. I just got some surefire parts including a A19, it seems to me you could keep adding A19's untill you run out of them as there is nothing to stop you from adding as many as you want. So has anyone tried to design a Regulation circut that will fit inside a A19, i was thinking maybe a 2 cell light with 3 A19's so that will give you 5 cell legnth, put 4 123's in it and a regulator of some sort, would offer good burn time on a N2 or P90/91. Semms to me that would give you good stable burn time. Granted it would be a little long but like it makes much differnce, as soon as you add one A19 it pretty much takes it out of the pocket size group anyways. Forgive me if the SF's are already regulated s it makes no mention of this on there site.

The only SF lights that are regulated right now are the KLx's and the A2 when available. Your idea is quite interesting, why not use a A20 that is used to convert the 9P->6R. It looks like it is half as long as the A19 and maybe a regulator could be placed inside this adapter and thus not making the light to long.

good point, i have no experiance with the other adaptors thats why i mentioned the A19 but a shorter one should work, I expect i could fit it on one small square of PBC, shouldnt be that big at all. Im trying to design the circut now, does anyone know the Optimum voltage/current of the N2/P90/91 Bulbs?

P90:
7.35V, 1.15A
P91:
6.25V, 2.35A
N2:
could be similar to the P90.

Thanks to Brock for the data.

thanks, if anyone has the N2 data please post as that is the bulb i want to use first.
