I have some Philips Advantage 850s for sale, $7 each. They are probably one of the most efficient T8 bulbs around. Great peaks in the blue and red.



PM me if interested.

From my research, those appear to be a 5000K bulbs, Right?

I'm looking for 10000K bulbs.

Yes they are 5000K. A 10000K bulb will have very little red light. Bulbs in the range of 4100K to 6000K are better suited for planted tanks.

I understand, but I'm trying to add some 10K bulbs in to get rid of the Green Glow in the tank. I already get 6500K bulbs for $2.

Thanks,

Not all bulbs in that kelvin range have the green hue. It is very typical for 6000 to 6700K; especially the cheaper made bulbs with a low CRI. As with any bulb purchase you need to first get hold of the spectral output graph and see what the bulb emits.

Beware of the Coralife 10,000K:
And the AllGlass 10,000K:



They both have that green spike.
