Just ordered Malkoff's last 2AA body only, and a smoothie BK Elite head with a couple of HO-E1A from Lumens Factory. I had been meaning to get that Malkoff body for a few years, and when I saw Gene's new design for the 1AA body, I figured he was also retiring this style of 2AA body to replace with something similar to the new 1AA body. My 2AA E body set includes the Outdoorsman, DSS, Vital Gear twisty (also 3xCR123A), UBHII (also 3xCR123A), and now the Malkoff 2AA. 5 is an odd number, need to find one more 2AA E Series body. Does it exist?
I have never had a chance to try Mark's HO-E1A. I have been using Tad Customs' A3712 lamps with 2AA, and they're better for 3.7V cells; with 2 Eneloop cells at 2.4V, they're a little dim. Should get brighter light and slightly more runtime from HO-E1A, which is 3V @1.15A next to Tad's 3.7V @1.2A. I'll save my Tad Customs lamps for other lights. Sure wish we could continue to source Tad Customs lamps somehow.
Edit: not the last 2AA body only... now the product page indicates there are 2 left. Buy one, two more appear!
