1.58 A on High =approx 1hr 15 minutes

Slightly worse run time performance compared to the Fenix L2D CE with the L2D having a extra low output giving 22 hrs of use.


Umm, not really. The Fenix L2D runtime is rated as:
General Mode: 9 lumens (55hrs) -> 40 lumens (10.5hrs) -> 80 lumens (4hrs) -> Turbo Mode: 140 lumens (2.4hrs). 55 hrs vs. 10 hrs makes a big difference IMHO.

One of the main reasons why I bought an LD20 was the flexible output. You have a very bright turbo mode as well as a low output setting where the batteries will last almost forever (plus several options in between).
