7500K has to do with the color of the light. Doesn't have much to do with how "bright" they are. </div></BLOCKQUOTE>7500K is also starting to get dark (or I should say less efficient) as it is very blue and equates to looking at everything on an overcast day, 5500K is bright midday sun with pretty accurate color representation, and about 5600K is an electronic camera flash.
5000K is classed as pure white light, go below or above that and the light is less white, and in terms of light sources will be less efficient.
Cooler light sources (5000k+) have higher color rendering ability and enhance all colors equally, however at 7500K you are moving way out of the optimum band and losing efficiency in terms of brightness and accurate color rendering. They will look very blue though and will work fine.
HID's in the 4800-5600K range offer more accurate color rendering and better lighting efficiency (more light). </div></BLOCKQUOTE>
either way their bright

btw thanks for fdbck
