Uses Cree's high-throw XP-E R3 LED!  300+ LED lumens!!  (Approximately 250 real "out the front" lumens)

P60 sized LED Drop-In.  Single mode (High only).  Takes 2 x CR123's or 2 x RCR123's.

Works with Surefire(R) 6P, 9P, 6PL, C2, C3, and others that use the P60 sizing standard.  This is the same module that is installed in the Dereelight CL1H V4 1SM XP-E R3.

Note:  Not recommended for Surefire G2 or G2Z.  The drop-in will not properly contact the inner metal sleeve used in these flashlights.  This will result in erratic operation, or it may not function at all.  In addition, high-powered drop-ins produce a lot of heat and are not recommended for these plastic bodied flashlights.

Comes standard with orange peel (OP) reflector installed. 

Outer spring is not required for use in most flashlights.  Try using the Drop-In module without it first, if it works, leave the spring off.
