I recieved a TLE-6EX for my 4D Maglite today. It makes an very tight hotspot. The focus function is pretty useless with either a tiny tightspot or a black-hole in the midlle of a larger hotspot. The output is much better than the multi-LED head it replaced. Compared to my Inova T3 it doesn't light up a room near as much when shining on the cieling. The hotspot is much tighter. It may have a little more throw power at long distances. I really like the spill, it is huge and very useaful. The T3 isn't as usefull a flashlight with it big blinding hotspot and not much else, more of a defensive flashlight than a work light. I hope the TLE has better run-time than the 30 minutes of the T3.
