I find the X200B to be perfect for use in my home, completely lighting up an entire room or hallway without a blinding spot reflection. I have seen photos of the X300's beam and while it seems to offer periphery coverage, the spot seems incredibly intense, while offering less periphery than the X200B. I have a cree in a G2 and it is much too bright in the confines of my white-walled house. I wish I could use an X300 for a night before committing to purchase one in order to confirm. The X200B is perfect for my applications within the home - I wouldn't want to regret the purchase of the X300 if it proved to be too much light. As a side note, isn't it outstanding that we can now talk about a small, light, bulletproof, weapon-mounted light as possibly producing too much light!
