Pelican 2760 Gen 3 LED Headlamp (Black)

With due respect to Kirk (staff who answered it), his answer is not accurate or true. The unit remembers what light color mode it was in the last time it was on, and that is the mode it will go into when you turn it on next time. So if it was in white mode last time, it will turn on in white mode the next time you turn it on, and likewise with red mode. (That is good, since if I had it on red mode, then turned it off, then turned it back on again, it will go straight into red mode again. Too bad it only has one brightness level in red.) Because it does not remember the white mode brightness setting (high, medium, low or downcast), and always turns on next time in HIGH white (if you had it in any white mode last time), it is irrelevant whether the white mode was in low last time (despite what Kirk said) and, in fact, if it was in low white mode last time, it will go to HIGH white mode next time. In other words, the brightness level of white used last time has absolutely no bearing on the access to the red light and if it was white last time, it will NOT go to red the next time until you have switched its mode once on in white. Annoying.

The Pelican 2760 Gen 3 LED Headlamp (Translucent Red) can accept any type of AAA form factor battery. Lithium-ion batteries will be the most efficient for powering the Pelican 2760 Gen 3 LED Headlamp (Translucent Red), but NiMH AAA will also fit.

Thanks for the helpful solution provided by the previous responder. I too was afraid of breaking the unit and actually contemplated returning the unit. Startup Instructions are not included. Would not consider gifting to avoid frustrating recipients!
