Whiter Lights?

[Reggae Fish]

I have 260 watt pc's (2-65 watt actinics and 2-65 watt 12k)
I'm looking for something whiter. Just more yellow than I want. What should I look for?

10k ?

10,000 k is typically considered the whitest kelvin rating. You could replace the 12k's with 10 k's, although I doubt that would make a huge difference. Or you could replace the actinic bulbs with 12 k's or 10 k's. Or you could replace the 12 k's with 6,500 k's. That might look yellowish though.

When was the last time you changed your lights?

 

[Reggae Fish]

They are only about 3 months old. They've looked this way the entire time but I'm just trying to figure out what I want when I replace them.

What about 2-10k and 2-50/50

 

[JxMetal]

That would be more white.

I'm just surprised that you're getting a yellow color with 12k's. If anything, I would think that they would be less yellow and more blue/white. My 12k MH's certainly are. They don't even have a hint of yellow to them.

Oh, I didn't realize you had too much yellow now. But still, 10,000 k's are basically supposed to be white. Your 12,000k's should be just a little blue. Do you have true actinic 03's? Or are they the blue 7100 k's like Jebo sells? True actinic's make it look much more blue.

If this is an Odyssea or Jebo fixture you need better bulbs.

My coralife bulbs (10K) looked pretty yellow.
