Surefire X300v

I have had more problems out of vampire series lights than any other light I've ever owned. I had to send my M952v in twice. Bought an X300v from Optics planet and sent it back immediately it wouldn't work in the cold (less than 40 degrees it stopped working). Sent it to optics planet they sent me another one it's worked well on my Glock for about 6 months and just the other day I notice a dark spot in the middle of the beam. Look at the diode and there is a black spot on it.
Should I send it back to Surefire?

I think it has to be needed a repair service.

Huh??

Geez..I've had the same problems with vampires, I've had 3, count 3 952vs, this last time I sent in my 952v surefire sent a m600 vampire. Worked fine for a few weeks, then it started acting goofy on IR. Sometimes it would "strobe" while in IR mode. I don't know what's going on over at surefire these days but I find myself using surefire lights alot less these days.

The LED is burnt and needs a replacement/repair.

Surfire's customer service for manufacturer warranty is reeeeeally slow. So if you can try to avoid that. Took me 2 months to get another XC1 when it was damaged out of the box.
