I loved this light, but sadly mine died during a camping trip. It may have had something to do with being submerged, but anyway I took the switch apart later and put it back together and it would sometimes turn on but usually nothing. I don't think anything is wrong with the emitter. I'll try switch disassembly/reassembly again to make sure I didn't put the spring in backwards or something, otherwise I'll see if I can get it sent in for repair.
