another lighting question

Hi
right now we have a 2 48" 50/50 110W WHO bulbs and 2 -48" Actinic 110W WHO bulb.
Thinking of buying 48" 10,000K 110W VHO Bulb - anybody know about these bulbs.
Oh this is for a reef tank. - 90 gallons.
Does it pay to put 4 of the same bulbs in tank.
Once Again, thanks for your help.
notsure:

I'm not familiar with WHO bulbs. Typo?
If you currently have VHO bulbs, you can go with four of the same type. If you use 4-10,000K bulbs, your tank will be very white. I would try 3-10,000K bulbs and one Actinic to give it some more blue. The actinic will bring out the colors of the corals more as well as fish colors. Plus IMO the tank looks better as a whole.
Go Illini!!!:cheer:
