I was at the La . Chiefs' of Police conference and spoke to a Streamlight rep yesterday and played with a TL2 and a Nightfighter. I am very impressed with these lights! One thing that I had not realized it that they are very close in size to an E2.
The TL2 xenon seemed brighter with better throw than my E2. The TL2 LED produced a very smooth and even beam with no trace of green at all and a suprising throw (some folks here may find the beam too tight, but I liked it). The hotspot was very white with just a trace of blue around the edges, but the corona got somewhat bluer. We discussed the TL3 and he said it would be out hopefully next month, and he said that they (and the TL2) are not regulated, just resistored.
The Nightfighter works great in the 'groucho grip' and seems also brighter than my E2. This particular one was the green finish, and it looked a lot like the finish on the CMG Ultras (not the brighter green of the Ultra-Gs). One thing that I had not seen in the adds for it, is that the pocket clip for the NF is mounted on the grip donut, so the light carries bezel down in your pocket. This may not work well in jeans, but I found it quite comfortable in a pair of Dockers.
He also said that they are working on a Twin Task (xenon with 10 leds) version of that magcharger-sized plastic body rechargable they make, whatever it is called (SL20?).
I am going to try to get a picture today of the TL2 and NF next to my L1. Based on my impressions from playing with these, I am going to backorder by a TL2 and TL3.
