I'm trying to decide between the E+Lite and the Zebra H30 for a backup light. My primary light is a Surefire L4, and I want the headlamp to serve as backup and flexibility. With that in mind,

The benefits of the H30 are:
Much brighter, and so more useful as a backup for the L4
Newer LED tech
Uses the same batteries as my primary light, no need to pack 2 types of replacement batteries

The benefits of the E+Lite are:
Cheaper
Lighter
Smaller?
Red light option
Strobe option
Known to be reliable (is the H30 as bulletproof?)

Any thoughts?
