FRITZHID you are a much more patient man than I am lol. Were you able to identify just which Cree emitters it comes with? If it were my build Id go XP-L HD but thats me. And alkaline D's have an S-ton of capacity 13,000-18,000mah depending on brand. Mountain Electronics is the shiz nit.
They appear to be XPL LEDs.
As far as the replacements, I don't currently have an uber hi CRI light so this seems like my best currant mod option for one since it's the only 3 up LED light I own. I could dump in the xpl hi but then I'd have yet another lumens monster that throws but CRI remains low. I already have 3-4 lenser throwers so I think this reflector based 3 up in hcri will be a nice addition.
Yes, Ds have great capacity but are heavy, leaky, thermally inactive in cold, poor self discharge, etc.
This light will most likely become my staple auto light so no leaking/self discharge is kind of a must. :/
+ side is the 219s don't need 6A/each for max output so alks would be plenty effective..... Until driver replacement.
But like I said earlier, all my projects are on hold UFN.
My mother is passing from cancer in the next few weeks so my wife and I are heading to NH until that horrible ordeal is over with and then I'll be back working on my projects again.
