New guy to the site so please go easy on me. First question out of the blocks, do extreme cold temps prevent a LED light from working properly? Do factors involve a voltage drop of batt pack? One of the past couple of really cold nights my magcharger with TLE-100EX/Cree would not fire up. The temp was definitely below 20 degrees and the light was in my car all day and night. After starting car and warming the light with the heater, the light worked normally. The batt pack is new and was fully charged.
Thank you for any feedback
