Compare the 7A tints: XP-L HI to XM-L2 - that's more equivalent. I think the XM-L2 7A's were like T2 or T3 - way lower than U2's. There are 7B3's now though in a T4 bin.
Sorry I’ve not worked it out. I tend to look through many pages to find interesting products as the search is limited. Fortunately some sales live the SSC are listed on the main page.
The KD HAIII BUCKLE V6 in red that I bought from KD was a real treat. A great little light for just over £3.00. I think I have an urge to get another one probably blue this time.
I mentioned the boost driver becasue the forward voltage of the emitter is far above the input voltage and the cells are in parallel. By comparison, this is very unusual for nearly all cheap flashlights, which are either buck or linear regulated.
Cree shows 1606 lumens at 2 amps for a J bin XHP50. With reflector losses, etc… that would be knocked down to 1285 lumens, which is probably far more likely with the grossly exaggerated chinese lumens we have all come to expect.
I was hoping/expecting that it could have done 3.5 to 4 amps, which would put it solidly in the 2500 lumen range.
Considering the BLF A6 can do 1300 or more lumens, I’ll pass on this one.
That link helps. The KD site has historically been hard to get around to find the best deals, but it is improving. The specials are worth looking at too, as they have a very broad range of torches, some have been around for a while, but great value.
