More economical than LED, is the "Home Depot Special" refugium light. The "special", as we call it, is a clip-on aluminum cone reflector and a 4-pack of daylight color twist PC bulbs. This combination costs less than half the price of an LED setup. The 4-pack gives you 4 years of light. According to statistics, you will not even own this setup 4 years from now. Also, these fluorescent PC bulbs in the Daylight color provide a better color spectrum for Macroalgae growth.
That's my 2 cents.
