I'm looking for a combat light and I am familiar with the products Surefire make. They seem to be very good, but are they the industry benchmark? Do they set a standard, or are they the "popular" light to have? Also I am looking for a tac light for my G19, and I am familiar with the ones offered by Glock, but are they any good? I am looking to spend max $200.00 (retail, if I can get it cheaper I will) for each. I am sure a good light will cost $$$ but I don't mind paying for quality. I am looking for something combat/tactically proven, reliable, durable, and long lasting, not to mention BLINDINGLY bright. Any suggestions on "particular" models would be appreciated.
