Enough or too much lighting?

Reef Tank: houses (8) coral, (5) fish, live sand, apprx 60lbs of rock.

Tank size: 37 Gallon, 30"Wx12"Dx22"H

Lighting: I combined fluorescent & LED

LED: 23 white, 4 blue, 1W LED's (10,000K & 460nm Actinic Blue) 1670 lumens
Fluorescent: T5HO 39W Actinic Blue & 39W 10,000K

Is this sufficient lighting? Please note the height of my tank. I just moved and changed to this (bigger) tank, so i felt the need to get the LED fixture to couple the fluorescent.

Actinic blue on 7.5 hours a day, ALL light on 5.5 hours a day.

I think it's ok. Your rock seems covered by coraline, it's ok.

Your corals look healty now, you'll know fast if it's too much, they'll bleach.

I'd say you're on the lower end of lighting but most of your corals look like low-med light so you should be fine
