RE: Kelvin options



After having set up my 100 gallon plant tank with half CF's (5000K 55W bulbs) 
and half CF (the typical 22W {I think they are 22W} spiral bulbs from Home 
Depot) I have found that my plants seem to do better on the Home Depot bulbs 
and they are a lot cheaper to use (at least half as much as what I paid for the 
CF's from AHSupply).  I am curious if anyone else has had experience using both 
bulb types and what their results have been.  The fish sure look better under 
the AHSupply bulbs, but, the plants do not seem to do as well.  Anyone else 
played around with the Home Depot style bulbs?  Anyone know what the Technical 
term is for the bulbs from Home Depot ~~laughing at my lack of knowledge here~~?

5000 would be much better than 10,000 for a planted tank.  10,000 is going to 
be very blue.

I run a mix of 5000 and 6700K bulbs in my aquarium.  I don't use metal halides 
though, just CF.  The best CF bulbs that I've used are the 92 CRI 5000K 55w 
bulbs from ahsupply.com.  They work well on tanks that are a multiple of 24" 
wide.

I have the parts on order to switch my 60 gallon planted tank from 6 T8 36W 
bulbs to 2 96W compact flourescent bulbs.  If anyone is interested in some high 
quality ballasts for T8 bulbs let me know. The bulbs that I have are way past 
their prime (although I think I have two high-CRI 36" bulbs as spares 
somewhere), but the ballasts are in good shape.  They are about a year old, I 
bought them from Bulbman down near the stadiums.
