Hey all looking for some input on a light for my AR. I am looking for something bright, good on batteries, durable and has pressure switch. Not sure on color of light, feel free to give me your insight on that topic also. I would like to keep it under $200. The four I am currently considering are: Orion H30, Predator Tactics Reaper, Optical Dynamics OD40 or Wicked Lights W403IC. Any info will be greatly appreciated. Thanks.
