Help. 2AA sandwich, Q brightness, long runtime. .

[Orion]

A co-worker is going up to the mountains in the near future. He is wanting a light that uses AA batteries, has the brightness of at least a Q bin, and has a fairly long runtime. What should he get?

Thanks! /ubbthreads/images/graemlins/popcorn.gif

The MadMax Lite will give him the long runtime and the "T" bin will be the brightest MadMax Lite Sandwich

the sammich hoghead mentionedwould be great.

also, though probably dimmer than the madmax (i think) the UK eLED might be a nice one. not a lotta throw, but still fairly bright with loooong runtime. might be able to use lithiums....but not sure.

UK eLED probably won't be bright enough. He wants it at least a Q bin in brightness, probably 400mA or so.

oops, yeah--i goofed. duhhhhhhhhhhhh.

get a sammich!!!

Re: Help. 2AA sandwich, Q brightness, long runtim

Some say that using a high ranked Lux in a low current applicant is a waste, but Wayne's idea is to have good brightness (not the most brightness) at a longer runtime with more efficiency and increased life for the Luxeon. By increasing the rank of the Lux, you are offsetting the decrease in power, maintaining the output.

The T rank in a MM lite should be close to a Q driven at spec, if not a little brighter (depending on vF).
