MODLITE PLHv2 - Higher Outputs Than Surefire
This is the best Surefire flashlight alternative on the market!

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 among different Modlite light heads with different capabilities when needed. PLHv2 is the most popular, and there are two more head options.

• PLHv2 1500 lumens (DF replacement head, 54K Candela)
• IR 1200mW (Infrared for night vision setup)
4X More Throw - ~400% more concentrated beam 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 switch or remote pressure switch accessories. If you have them already, then you're set!

What Is The Best AR 15 Flashlight Pressure Switch To Get?
There are many different pressure switch pad to use on an AR15. The gear selection is relative to how much the user understands weapon light use philosophy.
Weapon lights are used to PID in dark areas, and in some cases, a light can blind threats up close. Light activation doesn't always need to be constant on.
In fact, momentary on/off pressure switch is the best for tactical usage, because the light turns off immediately when the user let go the pressure on the switch. This is extremely useful in stressful situations.
For a true momentary on switch, please check out the ModButton.
For a dual switch, please check out TNVC TAPS
