Re: [GSAS-Member] Spectrum Effectiveness...was CFL bulbs

So this discussion brings backs a topic I have yet to find a decent  
answer to.  I get differing answers from every source.

Most of my fixtures have room for two bulbs.  I have bought one  
10,000K  so the tank looks good to my eyes and then the second bulb is  
6700K so the plants thrive.  I am not sure this is accurate though.

Now, I am looking at buying this 6500K bulb.  Why isn't it 6700K?  If  
6500K is better for plants, then why isn;' Coralife producing a 6500K  
bulb instead of 6700K?

AND, if I only get one bulb in some of my fixtures, do I get the 6500  
over the 10,000 because it is a planted take?

Can anyone give me some good perspective on this?

Thanks
Shango
