MODLITE PLHv2 - Best Throw

This is the best Surefire flashlight alternative on the market!

How Does MODLITE Over Surefire? - MODLITE is another AR15 flashlight that shares the same dimension as Surefire Scout. Its light head options offers higher candela and lumen output than Surefire M600DF (Light head works on Surefire M600DF as well)

Users can purchase just the light head and use it on Arisaka or Surefire scout light bodies or buy the complete set.

Interchangeable Light Head - Swap light head with different capabilities when needed. PLHv2 is the most popular, and there are two more head options.

mk18 with modlite okw head beam pattern
modlite okw vs plhv2 vs plh 5k head

OKW 680 lumens (Far throw, 69K candela up to 500 yards without dimming down)
PLHv2 1500 lumens (DF replacement head, 54K Candela)
IR 1200mW (Infrared)

Compare PLHv2 VS PLH 5K VS OKW

4X More Throw - 400% more throw than a Surefire M600DF and about ~27% more than the Cloud Defensive OWL. It's perfect long distance PID and threat control.

Tons Of Accessories - Use the same Surefire tail cap, mount accessories and remote switches. If you have them already, then you're set! 

Long & Short Body Available - Use 18350 body (Sold separately) for short barrel rifles and other compact AR15 setup. Uses 18350 battery that performs identical to 18650 battery

Why Use The Streamlight ProTac HLX - The ProTac HLX is similar to the Surefire M600DF at a much cheaper price for pro AR15 shooters to start on.

Uses 18650 Battery - Maximum lumen output like the Surefire M600DF up to 1000 lumens, and it's way better than using 2 CR123A batteries for the price you pay

Fast Stobe Activation - Double press to activate strobe, no other scout light on the market feature this function

Replaceable Front Lens - Replace the front lens as easy as the Cloud Defensive REIN without having to replace the entire light post field damage

Same Mounting Accessories As Surefire Scout - It uses the same mounting footprint as the Surefire M300C & M600. Use your existing accessories without buying proprietary parts

Pressure Switch Included - At no additional cost. Highly recommended to mount it with the Cloud Defensive LCS module to hold it in place on the handguard rail

Side Tucking Cord - 360 degree freedom to rotate the orientation of the cable to prevent getting tangled on foreign objects
