Finally on sale to the general public this summer and I just got one myself.
First light and laser combo for me. The 500 lumens is a clean white beam profile compared to my E2D Ultra which has a slight green tint.
The laser is a cool green (almost teal) compared to the standard green I've seen. I have a 532 nm green bore sighter in comparison to the X400 Ultra green which uses a 505nm wavelength.
