I've built a 2D mag running three Cree XRE LED's. Each LED is powered by one Micropuck SHO 500mA. I think these draw approx 750mA from the batteries per micropuck, so a total of around 2.25A.
What would happen if you run it on alkaline batteries? I'm guessing 2.25A is too much current draw for alkalines and you won't get full power to the LED's, plus the run time will be only a few hours?

! I am often cruel and unusual with alkalines such as pulling 2.5Ah out of D cells and they will drop of very fast and give only about 30-45 minuets of run time! However my most horrible deed is if I switch my SLA 12 battery power in my Bigbeam 1000 light to it's auxiliary AA mode "meant for the .24 Ah LED" and I have it run the 3 Ah Incan bulb! Instantly the bulb gets dimmer and the batteries would probably die in about 3 minuets! My rule of thumb is never to pull out more then = AAA .41Ah, AA .71 Ah, C 1 Ah, and D 1.25 Ah. Anything over that and the battery's internal resistance is so much that run time drops way off the map! So you LED light would be duller and only last for maybe a few minuets. The only way to get good performance out of Alkalines like the 2.5 Ah discharged D's Is that I over drive the bulb by 2 cells so when the voltage drops it more or less ends up at around what I needed. though it's still underdriven in the end!
