Seems everything is a compromise. I'm recently back into reefing and some of these new 14k- 20k 250w bulbs look awesome for the DT, but I understand they generally just don't compare to the good ole Iwasaki 6500's for growth. I used the 6500's back in the day and they out grew the AB 10k's 2 to one (for me anyway).
So here's my thought: run two bulbs (mogul) in my hood 180 degrees. set the 6500 on a timer for a few hours during the day while at work and a "display" bulb for the evenings. I have several ballasts from the old days so this is not a problem.
I still have a 660VHO ballast so actinics are a possibility, but frankly as I remember, they get pretty washed out under the MH.
Comments?
