I dunno, I have the UltraStinger LED and if anything its too bright (cant really use it looking into panels easily)... Its never run out of charge on even two jobs in a day and recharges in no time. I really like the Fenix lights because of their size and the brightness is pretty much the same (I have compared the two). What I dont get about them is 1: what batteries do you guys use (re-chargeable or not), and do you charge them every day? 2: where do you put it during your inspections? (pocket, small goofy holster?)... I love my stinger (the LED ones are way better than the old ones). I hang it off my tool belt cause thats what I'm used to. I am always open to new gear, especially when it comes to down sizing, I just dont understand how you guys haul them around. I want to get one (the tk11 or whatever) to use as a backup and for crawlspaces. I actually read a post on this site a while back about a generic version of the tk11, bought it for 25 bucks and it never worked. So, I still have all the batteries (regular and rechargable) but never used them... Shed some light on me guys...
