This host features low-key matte sand / desert tan anodizing along with a smooth reflector for increased throw.  As an added bonus, a deep carry clip is also included with this host.

For a single emitter build, just add a 16mm MCPCB+LED (Nichia 219C / Cree XP series preferred) and 17mm driver.  

To build a triple LED flashlight, you will need to add the following components:

• 17mm Driver
  • If you are running more than a 3.4A driver, you must bypass the tailcap switch spring using either copper braid or thin 22AWG / 24AWG silicone wire.
• (3) LEDs on a 20mm 3XP MCPCB
• Aluminum or Copper Spacer
  • You will have to drill and chamfer a small hole in the brass pill to allow the wires to pass through.
  • Aluminum is less expensive and lighter weight, while copper offers a small thermal advantage. 
• Carclo 105xx Optic
• Thermal Compound

This host works with protected cells, including the Protected NCR18650B and Protected NCR18650GA.
