Experience with Coralife 20,000K Flour. Bulbs?

Hi everyone. I have been using Hagen standard Flourescent Powerglo bulbs (18,000K) on my freshwater tanks for years. I love the look - nice and bright with a white hue with a hint of blue.

I know Coralife makes a high intensity 20,000K bulb. I am wondering if this might look even better?

I will be using them on a tall tank (29" tall 150g).

Just curious if anyone else out there has used them.

thanks,

12 Volt.

okay but you are using PC's right? these bulbs are standard (but high intensity) flourescents- I would be using 4 36" 30W bulbs.

green water problems aside - how do you like the colour? is it nice looking?
