So 1 16" would be enough if I hang it high enough? Would 2 be better if I dimmed them down, to keep the heat on the led's down? Or is that not a problem?

Specifically talking about the eBay led systems a single unit is enough to light up a 2 foot section of tank to grow any coral. If you raise the light higher to distribute the light more, it will help but not eliminate the dim spots on the sides. However, it will also decrease the amount of light limiting the corals you can grow.

Heat isn't an issue at all with led light systems.

Ok, the 24" is the way to go for my 36" long tank. As far as heat goes I didn't know about the heat in the diodes damaging the lights themselves, not so much heating up the water.

Just so we're on the same page, what fixture are you referring to when you say 24"

Wow, those are expensive. But yeah we are talking about different fixtures. I can't comment on those because ive never used them before... or ever heard of them.

Just so you're aware, bridgelux is what all the ebay brands use for the most part. If you're going to spend that much on a light, you might as well get one with cree or phillips LEDs.
