Ok i am in the market for a new tac. light for my G19 and have been doing some research on which light to get. I am on the fence on 2 lights. First is the .... * Insight Tech gear WX150 Tactical Weapon-Mounted Light and * Surefire x300 weapon-mounted Light. So here are some specs..... Insight WX150..... Peak Output: 150+ Lumens Run Time: 125 Minutes Interface Options: Adjustable Slide-Lock® Dimensions: 3.2L x 1.6W x 1.5H Weight: 4.0 oz. w/Batteries Waterproof: 1 Meter/3 Feet Lithium Battery Power: 6V from Two (2) 123 Batteries Warranty: Limited Lifetime Warranty Surefire x300 specs...... Max Output 170 .0 lumens Tactical Runtime* 2 .4 hours Length 3 .6 inches Bezel Diameter 1 .0 inches Weight w/Batteries 3 .8 ounces Batteries 2 123A Warranty lifetime on the original owner. Pics of both models on a Glock 19.... I love the brand surefire, i have owned many products in the past and have been very happy with all the products i have owned. But on the 19 the surefire x300 doesn't fit to well, and this is where the insight model comes into play, it looks great on the 19 and doesn't stick out as far. It looks like it was made to fit the 19. So what say you? Which would you get. I have found the Insight light for 159.00 shipped as for the surefire well 249.00 so with price in mind also, what do you think? Either way which ever that i choose i will have to send my light to NTAC to get my holster fitted for the light for the 19 .......thanks Wanna kill these ads? We can help!
