I would add that the TLR-1 was designed as a pistol mounted light. And it works very well in that capicity. Read indoor/short range. And yes,I own one.
The beam pattern tells you this. Very narrow. If this light will be used for HD primarily indoors or outdoors in a small yard then it should work great.....however...
If, like me, you have acreage or a large yard, there are better choices IMHO.
I have offically jumped on the Elzetta bandwagon. I got a Bravo with the AVS head and can tell you, with no ambiguity, that the beam this light puts out is simply amazing.
Just the total area that you can light up is massive, compared to the Streamlight. To take it a step further, there is no comparison. The Elzetta is superior in every way one could measure overall light performance. Throw and spill is night and day. Color of beam is incredibly natural. I don't think I've ever seen a weapon mounted beam like it.
In an outdoor enviroment, this could easily save your life. The ability to ID a large area, easily, cannot be overstated.
