I have the SR2000, too. Overall, I like the light, and haven't had any problems with it, but then it has not seen really rough outdoor use. I also purchased the attachment that provides a nice flood beam, which is the way I almost always use the light.
My one "complaint" about this unit is the charging mechanism. It is HUGE, and not the easiest to use. I don't understand why Koehler couldn't just use a simple plug-in charger, rather than a gigantic charging "cradle."
Just my opinion...
