bought a solar crank handheld flashlight off ebay that never worked that well. took it apart to find nimh battery 40 ah 3.7 volts so it should run these leds better than it does. one way to hack it is to take it apart pull off one of the 3 led’s and reassemble.
received a vein finder flashlight with a pinkish light. had placed the 3 aaa battery’s into it turned it on and it instantly made me feel strange and sad. would not recommend buying a pink one.
more flashlight reviews to come.
