The heat transfer is optimal in this flashlight.
The brass pill and the dissipating mass around this help greatly the heat transfer to the surrounding environment. I can add that the threads of the zooming mechanism act like a dissipator (in throw position) because the surface of heat exchange is increased.
The xp-l high intensity is relatively new on market so some bins are still in shortage.
At this time are available 1A and 3B but there is possibility to have a BIN with lower color temperature in the next future.
Cheap lens ??? The aspherical lens of the COMETA is outstanding thanks to the double AR treatment and the construction in borosilicate K9 glass with refractive index of 1,52.
Application of a layer of a quality termoconductive paste between pill and the MCPCB. There is a cover (see the review) in anodized alluminium the fix in place centering the mcpcb.
The 18650—>26650 is widely available in the market at around 1 buck.
Yo can use also a piece of sponge to fix in place the 18650 so that you don’t have any “maracas effect” :bigsmile:
Like Bugsy said we are working on battery discount.
The LG HE2 is an IMR battery so has a lower internal resistance that permits a higher current flow.
A protected battery has a lower attitude to deliver higher current because has the PCB that acts like a “bottleneck”.
The review’s sample has a turbo step-down of 50 sec.
Thanks a lot Bugsy for your support in answer the questions of members
