Any LED for refugium?

[Thomas Weber]

Looking to grow chaeto in my sump with a 2' LED strip light that I found. Will the chaeto grow? or do I need a special grow light or CFL.

I beleive this is the light. https://www.1000bulbs.com/product/1...0QZkQmxz_qHSXi3r48_w6YAR7NZ02jLQaAlr4EALw_wcB

It'll probably grow some, but not nearly to where you want it, I think... That's basically office fluorescent lighting, just in LED form. It doesn't have the proper color spectrum for photosynthesis. Plants grow best when they can absorb red, indigo, and ultraviolet light; my advice would be a Kessil H80 Tuna Flora, it's great light, and isn't terribly expensive. But you could also get away with any LED grow bulb that Home Depot sells now.

Something like this, for example:
