Refugium lighting help

[bakbay]

I have an old CWT-50 sump and would like to fill the center chamber with Chaeto. What do you guys suggest? I’m contemplating about getting this:

NICREW ClassicLED Marine Aquarium Light, LED Light with Dual-Channel Timer for Saltwater Fish and Reef Tanks, 24 to 30-Inch, 24-Watt https://a.co/d/8wOsOXv

What do you think? Something else I should consider? Thanks

The skimmer will come out — I was just testing it. Definitely don’t want chaeto to get inside the impeller.
