9325K The Difference - Page 12 - Lighting

To Newt,
(other opinions are also very welcome)

As I mentioned earlier that my 48" fixture can hold a total of 4 straight pin compact flourescent bulbs. In your opinion, what would be the best set of bulbs or combination that would grow plants well and provide a nice balance of colors b/w red, blue, and green?

Right now, I am using four 65W 6700K bulbs that were shipped with the fixture. Each one is approximately 22". Since those were included with the purchase, I know nothing else but the color temp and wattage. Those bulbs tend to promote the green color and disminish the red. Everytime I turn on the light, the redness of my cardinal tetras and flame dwarf gouramis is diminished and overshadowed by green.

I like the Philips PLL950, 5300K, 91CRI. It has a nice white light.

The 6700K bulbs do have alot of green as seen in the gif below:

Coralife 6700K:

Newt,

Are you using all Philips PLL950 in your fixture or do you mix them with other bulbs?

Do you think it would be a good idea to use a combination of two 9325K's with two PLL950's? Would that combination be able to grow plant well and create a nicely balanced color spectrum?

Newt, may I ask where you got the PLL950? I could only find a PLL950 that claimed to be 5400K with a 82CRI. I have the 9345 and like the idea of pairing it with high CRI bulb as you described.

I just upgraded my lighting to T5HO Midday but used the PLL950s for years and have used them with many other combos including 9325 but usually with GroLux. I think I had great results.

No, it is not. I don't remember the manufacture. I purchased this system on ebay.

Where can i get GE 9325K and 6700k bulbs from the same supplier to save on shipping.

Hello all, any experiences of the Aqualine T5HO from anyone?
thanks.

For the $$$ I shelled out for a TEK 4 bulb x 54w fixture and Giesmann Midday bulbs I was just as well off with the Philips PL-L/950 CFs. Actually, I think my red plants were more red with the 950s which equates to a stronger blue light.
