Used Bulbs

[Grunk08]

I am not sure this is the correct forum for this but I am getting close to buying new bulbs. I am currently running 65w pc. They are 10,000k/6700k and 460/420. Does anyone have a used 10,000k bulb or a 10,000k/7100k that I could see if I like the look better than what I currently have? BTW, they are square pin. The look I have now is a little to yellow for my liking. Would there be any advantages or disadvantages to getting away from the 6700k bulbs?

Usually the more yellow you go (ie 6700k), the faster growth you get.
