This is the Malkoff Devices P90 style High Output Drop-in LED Upgrade Conversion with solid brass heatsink construction.  The output is approximately 800 measured out the front lumens at turn on and 700 continuous.  The Lux is approximately 8500 at one meter.  The current draw is approximately 1000ma at 9 volts. The full output runtime is approximately 45-60 minutes on three CR123 primary batteries with a nice long taper as voltage drops. It will easily illuminate objects at 200+ feet and will blind opponents within a 100 foot radius. The LED is a Cool White (6200K) Cree XP-L. 

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 the Malkoff MDX-16.5 Head with the Malkoff MD3 and MD4 Bodies and Surefire 9P, Z3, and C3 Flashlights.  It may or may not fit other models. The input voltage is 5.5 - 12 volts. Below 5.5 volts it will drop out of regulation.  Below 5 volts it will begin to flash and below 4.5 volts it will shut off.  This dropin is protected against reverse polarity.

This Malkoff Upgrade is 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.

Things to Know Before Purchase:

A M61 Lens Kit, or suitable equivalent, is required for use in the MDX Head.  This is available on the Malkoff Devices Flashlights Parts webpage.

This dropin was designed to operate at maximum output for extended times in metal lights.  Operating the unit for more than 15 continuous minutes on high in plastic lights may damage the dropin.  This is not an issue in metal lights or plastic lights with a metal head. 

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