4' long LED refugium light fixture?

[victor_c3]

I'm looking for a LED light fixture that would be appropriate to grow chaetto and other macro algae in my refugium. I'm planning on running two 4' long x 16" tall x 2' wide tanks as a refugium on an alternating lighting schedule. I'm not sure how much power I need to get decent algae growth in my refugium.

Or should I just skip LEDs and go with T5s? I'd prefer to go with the lowest maintenance effort.

Thanks for your thoughts and advice!

Not a specific recommendation, but lots of led grow lights on amazon would fit the bill, depending on how high you can mount them 2 might work as most seem to light 24x24 areas.
