This is the light that helped me rescue the kitten a few weeks back. The 70.3 HD from KaiDomain came in and was installed without any trouble. About the most simple swap imaginable actually.
The 70.3 HD is maybe a little brighter but I honestly think it's a trick of the better tint. The original 70.2 was GREEEEEEN. This guy has some tint shift at the lowest level, barely any at medium, and no perceptible shift at high. It's quite a pleasant looking beam. I would recommend upgrading to the 70.3 if you have a light you like with a 70.2 in it.
Bright! Neat.
