I just want to tell you how happy I am with my 7736D LED Light. I use my light to inspect my UPS tractor and trailer during my night working hours. I started out with a comparable Surefire light and your light out performs it hands down. I’ve been using it for 2 months now with out a battery change and the bright light it gives off is as bright as it was when I first got it. Thanks for providing me with a tool that helps keep alive.
