Hi Nascar
I sent an R2H to LED ASAP to put into mine, so i wont know the *exact* brightness or runtime of the ones youll be getting, but mine breaks down like this:
Runtime off a fresh duracell M3 is approx. 1hr 15min. When mine drops out of regulation it doesnt dim, but it starts to flash, slowly at first, then faster as the cell gets more depleted. Shutting it down and letting the battery recover for a few minutes will give you about another 10 minutes of regulated light.
Brightness is good compared to my stock AAA LE. Its a bit too close to call, but id guess the LS was maybe twice as bright as the 5mm. The vast improvement is in the colour and beam quality. Mine is very very white, which surprised me, as i have an R2H in a mclux, and this gets noticabley green once out of regulation. Certainly a big leap forward compared to the blue, blotchy standard AAA. I should tell you that i got mine with the cut down acrylic ball for a lens with mine, so it does throw better than the stock AAA. Not a match for a properly driven LS with optics, but it will throw a small square of white light out to 10ft+. Im not sure how the beam will be,compared to a bare HD luxeon in the arc aaa head. Perhaps polishing the reflector will yield even better results?
All in all, i am very much taken by this pocket marvel, and it has opened my eyes with regard to underdriven luxeons in general. I was hesitant at first to send an R2H to be put in an *underdriven* mod, now im glad i did. Id be ordering a microilluminator to compare if my credit card could stand the abuse, but its had enough /ubbthreads/images/graemlins/frown.gif
Now if i could talk a lathe guy into cutting down the Arc AAA body down to N size, i'd be in hog's heaven....
Sorry for hijacking your thread Gene, but if youre considering a MicroIlluminator, then this is one light you should also be looking at /ubbthreads/images/graemlins/smile.gif
