A single metal halide should light a 24" x 24" area just fine and for 150watt up to about 20 - 21" depth. I had this lighting my 24" tall tank for a few months and Acroporas (one of the most light demanding corals) grew like crazy sitting on the sandbend directly under it. Price is on the first post. Bulb is only a few months old (which is the expensive part most of the time in buying used equipment - eg, if you buy a used fixture for a good price but the bulb is over a year old, then you'd have to spend $80 on a new bulb right away).
