YES!!!... The head is interchangable between the L1D-CE and L2D-CD... The chip knows the "burst mode" (90 or 135 lumens) based upon the voltage input: 1~1.5 = 90 lumens burst OR 2~3 = 135 lumens...

I own both and they are GRRREAT!...

IMHO, The Fenix L2D-CE is the absolute best flashlight for the money and covers just about all your bases in one flashlight! Hoorah! <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />
