Good bulbs... just another hint that Kelvin numbers are meaningless...

The color temperature of the bulb is meaningless for plants.

If you think that the higher the K, the better the bulb, you are mistaken...

K values are meaningfull to saltwater stuff, but apparnetly not freshwater plants.

Check out my AquariBlog for tank progress and updates!

I recently read that aqua-glo and powerglo bulbs are not actually 18,000K like it says on the box. The site I found said both in the range of 5000-6000K. Both are quite good for growing plants I believe.

Right now I am using a power-glo and have been impressed.

Those ought to be good grow bulbs, if they can really get the red peak up that high. I have my doubts; been told by a knowledgeable manufacturer that phosphors for high red peaks are very expensive.

I use Aqua Glow and Power Glow bulbs.. they are both excellent for growing plants. I have no complaints. My 45 Gallon is lit with 2 power glo's.. my 135 has 2 power glo's with the GE CF bulbs... My 90 Gallon has one Power Glo, my 30 gallon has a Power Glo... I could go on

would running some 30Ws on a 36W ballast count as overdriven? i may buy some 30W's instead of the arcadia's thanks to everyone for the feedback.. shame they aint actually 18000k. i thought it was to good to be true, at the price..
would running some 30Ws on a 36W ballast count as overdriven? more to the point. would it be safe

I would have to say they are pretty close to 18000k... They are absolutely not anywhere near 5000k.. The bulbs look more purple then the GE 9300k bulbs.

Are trying to run these T8 bulbs in a Magnetic ballast?

Then your set.. just plug in the bulbs and your good to go. And no, you arent overdriving the bulbs.
