I would say from my experience is find a light that has the strongest and the most broad-spectrum you can fined. Depending on the depth of your tank you would need upwards of 300 W or more. But that's just my opinion. I am looking to get a light from https://sbreeflights.com they have a good spread. Or something like Coralife 24 Inch Aqualight Pro, 1x250W HQI Lamp + 2x65W CF Lamps Sq. Pin + 2x1W LED but the size you need for your tank. I have the coralife light and it will grow anything I put in the tank but the problem is that it gets hot. To the point that in the winter I do not need to heat the tank and in the summer the AC barely keeps up. And on top of that the Electric bill is very big. On average my bill will go up by about $90 to $110 a month when I run the light.
