You will want a grow light, not a fish light. The spectrum is better for plants. Something like this (which I used)

I liked that it had a timer, intensity controls and could operate 1, 2 or 3 light head (with some limitations). If you are referring to the CPR HOB Refugium, the three arms of this light may be positioned in ways that provide better coverage. There are several similar options you can find as well

I would recommend for full benefit to run the light at night. If you are handy you could certainly create some kind of cover. It will be beneficial if your pH drops at night.
