This design utilizes a custom orange peel reflector designed by Don McLeish.  The reflector offers a very nice balance between throw and spill.  It is an outstanding room lighter and short to medium spotter. It was designed specifically for use in SureFire 3P flashlights. It may or may not fit other models. The input voltage is 0.8 to 3 volts. It requires 1.8v for full output. It is ideal for use with one CR123 primary, two 1.5v AA lithiums, or two rechargeable AA NIMH batteries.  DO NOT USE A SINGLE LITHIUM  RECHARGEABLE CELL.  YOU WILL DESTROY IT!!!  The LED is a White (5700K) Luminous SST-20 or Warm White (3000K 95 CRI) Luminous SST-20.

The M31 is protected against reverse polarity.

This upgrade was designed for rugged service from the ground up.  It is fully potted to stand up to rough service and recoil.  This item is covered by our Lifetime Warranty. 

WARNING: This light is capable of causing eye damage at close range. Please use the light responsibly!!!
