Hello. I just recently fried 3 drop-ins while messing around with different batter configurations. Mostly just experimenting. I have never tried a 3v-18v drop in. If you are running low voltage - like 3-AAA is it significantly underpowered? Does the brightness vary greatly depening on the power source? Right now I have several low voltage LED's and several hight voltage ones. Is that the best solution?



On a side note, one of the drop ins fried was an Ultrafire 4.2v-8.4v, and blew within 10 seconds from two RCR 123's. Shouldn't it have been able to handle that? Are my RCR 123's faulty? I don't dare to try them again and risk blowing any MORE drop-ins. Thanks in advance, you guys are awesome.
