Well I finally got the lights that I have been waiting for since before christmas! I am running a Sunlight Supply pulse start twin ballast w/ built in timer, and Pendants for mogul bulbs. The bulb of choice was the XM 10k 250w. My tank is a 55g soon to be upgraded to a 90. Well enough typing here are some before and after shots w/ the vho, and then the new halides.
