Not yet, or at least if they do, I haven't found them. I am waiting to see if GE will jump on the T-5 bandwagon adn make a 9325K lamp. Until then, I will just use T-8s.

If only they made them in 96w format...

Hanzo,

See if your ballast can run High Pressure Sodium Bulbs. They have the red spectrum you seem to be looking for. No MH will have that. By nature they are very much in the blue. If you get a bulb you like the visible light output from in the 4000K to 10000K, they will be fine for your plants. The popular choices these days are 5500K and 6500K. The latter less yellow, and probably your best bet.

Raul,

Check GE's website, they might now

If not, there is always Retrofits

To me the best image is the 5000K and the GE 9325K. The 5000K must have a fairly high CRI to compensate for the low CRI of the 9325K. I really hate the coralife 6700K as it has a huge green spike in its spectral output, as do most of their bulbs.

Do the 9325k bulbs actually do anything for the plants? Or is it purely for cosmetic looks? I got a 4X65W over my 55 gallon, and I'm just wondering if those 9325k bulbs are only for looks. Will still have adequate lighting with just the 2 6700k bulbs. With such a low CRI rating, how useful are the 9325k bulbs for the plant growth?

The plants dont care what the CRI rating is the see light as a spectrum. Blue and red light are what is used for photosynthesis. The 9325 has a blue spike in the proper place and an orange/red just below where it will do the most good. So the 9325s will grow plants. The kelvin rating is purely what appeals to you as the viewer.

Here is a link for the users of the GE 9325K bulb. They are selling them for $13.22 each.

I think the 9325K bulb is a marketing gimick in that I really don't believe it registers at 9325 deg. Kelvin. If you compare it to a 10,000K bulb (or a 6500K or a 5000K) it actually appears pinkish which would put it at about half the kelvin it is marketed at.

I really like the look of these bulbs but can they be had in NO florescent or are they only avaliable in CF? Is the a regular t-8 or t-12 bulb that is comparable to the GE 9325's?

Justin Fournier · 04-01-2004, 10:39 PM

They can be had in the form of NO. Not only can they be had, but you can have better!!

Look for Zoo Med's Flora Sun, T-8 in whatever length you need. As far as I know, they have the highest peak in the red spectrum of any bulb out there. It's a TOP quality product. If my memory serves me correct, it's over 650nm!!!!!!
