Convoy S2+ Running Very hot

I have the Dessert Tan S2+ with only 3 drivers (7135X3). I purposely ordered it that way, so it would never get too hot to hand-hold, and I could loan it to my wife without concern. Even with only three drivers (approx 344 lumens max) it gets very warm after about ten minutes, just short of too hot to hand-hold.

That’s probably because 7135 drivers are not very efficient when the battery voltage is high. One thing I find about the 8×7135 Convoys is that they’re probably more efficient than lights using less chips.

Hmmm, according to this thread HERE, three drivers should be the most efficient:

relative to 3×7135 (100%) the lm/A efficiencies are:

4×7135 313 lm/A -> 95%

6×7135 288 lm/A -> 88%

8×7135 268 lm/A -> 82%
