I think you are going to want a lot of blues to offset those yellow LEDs (5000-8300k) You might want to look for ones that are 10,000k or maybe even a bit bluer.
Youre right, I definitely don't want that yellow hue.
The pc's I have give off too much yellow and they are 10,000k. Is that the same as the LED's as far as color? Will I want to go more than 10,000k?

The 5000 - 8,300k were the whites and there are 12 of them.

The blues are a royal blue Cree xp-e led and there are also 12 of those. Should I keep it 50/50 or should I just get less white and more blue to offset the yellow...
Way too many variables for me to discern the best way to go.
If I get less whites and more blues am I decreasing par?

Here's a pic of the description of the blues...

Here is a list of colors for the xp-g line on the Cree website.... I don't see anything higher than 8,300. My only option may be to get less whites and more blues to get the desired color.

Then it's going to have to be the 8000k lamps and use the blues to offset the yellow. I would look at other fixtures and see what they do.

I just read on another thread your post about you upgrading your biocube to LEDs. How did that go?

I have not decided yet whether I will or not. I will decide when the stock lighting needs to be replaced after dic months. I like the idea that you don't have to replace the LEDs every six months, but they are so darn expensive :/ all I would get anyways because of the increase of lighting from the LEDs would be a BTA. It's not like I can get all of these new types of coral because of the new lights.
