That is a weak light if you are interested in nutrient export with macro algae. Anything between 5K-10K color spectrum. When you spec your light look for PAR or luminous numbers, they don’t lie.
I am using a hygger full spectrum light on my refugium of similar wattage and it’s working great to grow chaeto.
When I operated a macro algae refugium I used PAR38 lamps at 5000 color spectrum and 11W each. The bulb was $5 and damp proof pigtail was $4. Put as many as you can fit.
If that whole area is available, I would use two lamps to maximize nutrient export. If you just want a refugium to grow pods then one lamp is enough.
I've been running the Hygger Freshwater Full spectrum 22w over my refugium since 2/23. My fuge measures 20"x20"x15" and the fixture is hanging about 12" above the water line. All of my macros do great under it, and I have both reds and greens. Very pleased with it.

I received mine 12" a few days ago. At first the color combination/options don't make much sense for a saltwater light. I'm not sure I will have the time to see any results as the suctions cups are weak and the device floats. Should have been designed to hold itself down.
