Lighting questions

all depends what 4x24 watt fixture it is. depends on what type of reflectors it has. a single reflector fixture, nope. a Individual reflector fixture, yes. also depends on your bulb combo. Some t5 guys run pure actinic's to bring the par down for lower light corals while others would only run like a actinic plus to still get the highest par as possiable.
