Is there another thread that briefly explains the XR-E vs. Luxeon? I am familiar with Luxeon but have no info on XR-E to compare the two. Which one is brighter, more efficient, runtime, etc... Thanks
The Fenix P1D (Lux) and P1D-CE (cree version) exits. Check this thread.
He did a run time and total light output on a similar engine (me think and most agrees).
So If both are making the same output, Cree will run twice as long. On the same run times, Cree will produce twice the output.
