The ideal driver would be similar to the ideal flashlight and have 2 (LH) or 3 modes (LMH), no strobes or SOS. Mode memory would be good. If the modes can't be set manually, they should be about 5%, 50%, and 100%. Input only needs to be one li-ion cell. Output should be 1200-1400 mA with good regulation. I'm not finding that yet, so I have been looking at NANJG drivers with 1000 mA of output.
'''Programmable Drivers''' Some drivers, like the AK-47 and the 101-AK have an Atmel Tiny13 chip on board. It is possible to reprogram this chip to get not only exactly the number of modes and the light levels you want, but also to program it to be programmable. More information here at [[AVR drivers]]. So far I had some success in uploading a program, but the clip broke before I could customize anything and the program I uploaded gives a low battery warning all the time and won't stay bright. '''Perfect UI:''' Eventually I'd like to develop a programmable UI where one mode would be 100% brightness and the other would be programmable. Maybe you could flash the light five times, it would blink twice to indicate you are in programming mode, and then you could cycle through a number of modes (don't think ramping is worth the trouble; I like the idea of preset levels). This could include a very low moonlight mode, a map-reading low, an outdoor low, a couple of mediums, as well as some blinking, SOS, strobes, etc. If you leave the light on in that level for 5 seconds, the light blinks twice to indicate it is memorized, and you are out of programming mode. The UI would have memory that would set after about 1 second on.

I've ordered a clip to attach to the chip and a USB flasher and hopefully can try it out using WinAVR. More information [http://budgetlightforum.com/node/799 here]


'''<U>KD 13.5mm Driver</U>''' No details to speak of, but this 5-mode driver could be useful in fixing AA lights with burned out drivers where standard 17mm drivers are too big [http://www.kaidomain.com/ProductDetails.aspx?ProductID=11063&AffiliateId=1890 KD]
