One of my DX MTE SSC P7 (phew!) torches is playing up a bit - when it first switches on it gives the 'full' power, but then quickly dims and goes to approx 2/3rds power across all of the modes. I've tried it with 4 different batteries and compared it with my other DX, so it's definitely the torch. Had a look inside and can't see anything obviously wrong and nothing appears to be 'loose'.
Anyone else had a similar issue and how did you resolve?
