I use the catalina aquarium 20k bulb. Its like 30 bucks. It has great par for a 20k bulb (looks more along the lines of a 14k to me). I figured for the price, I can get two of those bulbs for the price of a ushio or AB bulb. I've had the AB 10k and without sups its waaaaaaaaay too yellow for me. LINK

It took about three days to arrive. I would definitely buy from them again.
Has anyone done Spectral Analysis of 70 watt MH Lamps & ballasts???
I've found the results on 150 watt bulbs/ballast but not 70 watt.
