So are the 15K hamilton's Metal Halides? Is that what is making the color that nice blueish and making things pop?

I just replaced my 150W MH and got 14K's, but my husband just grabbed the dang coralife bulbs off the shelf and didn't care that I was wanting to research more on bulbs. He likes the look, but I want the colors to stand out more. We went from 20K's to 14K's because someone told us that the 14K's are better at stimulating growth. I may convince him to let me buy something else and sell those on Ebay or something.

Anyway, I have a 150W 14K (I believe) Phoenix bulb in a clamp on I got from someone and the color is much better with that.

So the question is...what's the deal with these bulbs making such a nice color...and from your experience would you guys recommend switching to them? And if there is some other type of bulb that is even better, what would that be?

Thanks!!!
