hey, so the amber LED that I ordered got here, and it was working great. problem is, I left it sitting on for about 5 minutes by accident last night and I noticed a massive drop in brightness. do they really drain batteries that fast? I've had my blue LED on for an extended period of time as well, and it didn't dim half as much as the amber did. I thought the amber took less power than the blue. has anyone else noticed certain colors drain batteries faster than others?
