You can find blue and red LED grow lights in all sorts of configurations very inexpensive on Amazon for a fraction($30) of the Kessel and they work better in my experience.
I have the tunz under water to help heat the aquarium with this cold weather. Really grows algae well, versus the eBay led light I had on previously. I’d happy with it and it looks clean
Search for clamp on red blue LED grow lights on Amazon. It does not need to be a par 38. I use the square ones with hanging chains on that page. I removed the chains and screwd mine directly to the undersind of my stand.

I use black box style 300w hydroponics led lights. Keep in mind. You must provide intense lighting to your refugium if you want to outcompete the intense light in your display.
