Lighting a 24 x 12 x 18 deep refugium

[Cthulukelele]

I am setting up an external refugium in a 20 gallon tall. I already have an h80 with gooseneck from my previous setup, but my concern was that isn't enough light for such a big fuge. I am planning to add this light:

SGLEDs Full Spectrum Plan Light Bulb LED Grow Light Bulb A21 Bulb Grow Light Bulb with Ceramic Technology Plant Light Bulbs E26 Base 36W Grow Bulb 400W Equivalent for Indoor Plants Seed Starting https://a.co/d/aPTePHZ

It will be in a clamp on reflector lamp. Is this a reasonable choice? Thanks!

Yeah the h80 I got with the other equipment when I bought the tank years ago now. It's just not super bright hence the extra cheap bright light. I'm in your camp for growing algae light is light lol
