How much warm, and how the warmth moves inside 3 hand held flashlights, that have an output of several thousand lumens each?
All lights are running with the recommended IMR Batteries, all at turbo mode.
If you look at the runtime charts, the X7 is the light that can mantain the turbo/high modes for the longest period, compared to the other ones.
Thanks to: AntoLed for the thermal camera, Zampa for the tripod.
