I went 6700K, and I voted with my pocketbook, three times. In all fairness, I don't know what AHSupply's 10000K bulb looks like, so that's really not an informed answer.

Ever notice how much more yellow the light seems to be once water is in the tank? I don't mean due to tannins, it just struck me how blue the 6700K light looked before water went into my tank compared to an hour later after I filled it.

Hm, don't know Tony. Hadn't though of that, since I'm still looking through the glass when the water is not in it.

Starphire. Now that's something I wish I could afford. The clarity of acrylic without the maintenance headache. No way would I (the Klutz) attempt an acrylic tank.

I picked 10000K, but really like the 8800K bulbs (that can be bought at Champion Lighting and Supply) better. 6700K is too yellow for my taste.
I saw those 8800K lamps at Champion, will they work in the AHSupply setup?

I have two 96W AHSupply CF lamps over my 90 gallon, both are now 6700K. I'm thinking about swapping one for either a 8800K or a 10000K/actinic combo. Some of the local LFS are using actinics on planted tanks and I like the darker look. I'm assuming that the actinic is producing usable PAR even though they look dark.

So long as your AH ballast takes square pin [::] bulbs, they'll work fine. I think the consensus on most of the boards is that actinic doesn't produce any useful spectrum for freshwater plants, so you'd be better off using an 8800K or a full 10000K bulb.
