This light: Four LEDs x four 18650, five inches long and two inch (2.0) head diameter, weighs one pound with four cells, 277 grams without batteries.
Nobody is interested in this basic, fundamental, simplistic, mid-range form factor? I skipped this light when it was new and super hot, because 2.5 inch lights yielded much more power or much more throw.
Now, with the passage of time and the release of newer emitters, I think it is time to take a look at this form factor and ask if two point oh inch head diameter lights, such as this light, can be upgraded to put out many more lumens. Such as 8,000. (4 x XHP50?)
Also, there is the SX25L3 with 1.85 inch head diameter, three 18650 cells and a deeper, larger diameter reflector for a single emitter, for more throw. (single XHP35?)
I realize that 2.5 inch pop can lights yield exponentially more power than this two inch diameter light, and I also realize that 1.6 inch diameter lights are oh so much more edcable, even if they are currently ceilinged at only 3,200 lumens.
But I think it would be a good thing, if the dormant yet attractive form factor of the TM06 and the SX25L3, currently dead as a doornail, can be revived via being power upgraded with modern emitters.
