Just got my E1. Here are a few things I noticed.
The magnet is pretty good, it easily holds the weight of the light with battery installed.
When the primary LEDs are off, the rubber cover on the pushbutton glows with a fairly bright, cold white from 4 mini LEDs. It does make a pretty good moon mode, but I wish it had a warmer tint. The trim ring on my light is not glued, so I may just see about replacing thos LEDs with something warmer.
When the primary LEDs are on, the pushbutton glows orange. That orange led can still be seen through the primary optic when the primary LEDs are off, so that orange led is always lit whether the light is on or off. There’s no mention in the instructions about the orange light.
I have not disassembled the light, but build quality looks good.
UI is easy to use and uncomplicated, but the modes all seem too close together. Low needs to be lower and the difference between high and turbo is barely visible.
I like the idea of using the switch lighting as a moon mode. I hope to see this on more lights.
