I went from 250 watt DE 10k with 216watts worth of actinics to now using 250 watt 14k DE ushios (galaxy ballasts) with 160 watts worth of 22k t5s from aquascience. The 14k ushios seem a lot brighter but I think that's because they run almost purely white which I'm loving because this allows the 22k HOT5s to add just the right amount of coulouring for my personal tastes. Any much more blue and I don't think I'd be as happy. When the halides go out the 22ks are quite blue and my neighbours are always commenting on how my house glows blue at night.
