right now, next thing to haildes would be t5. t5's with individual reflectors can be stronger. they still put off a bit of heat from what ive seen. then vhos and pcs.
but unless your keeping sps or clams, you wont likely need t5 or halide. One of my local reef friends has a 75 gallon with 4 vhos. 2 actinic and 2 10k i think. he has softies and a ton of zoanthids.
