How high do you hang your lights?

[EyeReef]

I'm hanging my 6x54watt t-5's at about 4 inches off the water..
Debating whether I should raise it or lower it...

How high do you guys hang your lights?

My PC lights are about 5-6in off the surface and they would be fine except they get splattered by a HOB filter.

I would raise it due the salt crap a lone; I would say 6” min. Water splashing and salt buildup can really damage the lights.
