FWIW, my TL-3 LED is my first 5-watt LED, and I'm very happy with it. Blows away all of my 1-watt LS LED lights and drop-ins. I'm not sure it is worth the $100-120 that some dealers are asking for it, but I was able to pick it up for $85, and I'm happy with it for that price. If I wouldn't already have several 2 and 3 cell 123 incan and LS LED lights, I'd definitely be picking up the other lights in the Streamlight TL line.
