Welcome to R2R!

White light does ok, but heavy red seems to be the best. BRS investigates below

Red and blue is best as it promotes chlorophyll A and B in macro algae. The warm white lights do work, but they throw in alot of green and white and yellow into the spectrum that isn't as utilized as red and blue.
BRSTV Investigates did a really good video on fuge lighting

I decided to go with an H380, arrived this morning, just got the UPS notice. I have heard nothing but positive reviews on them. I am 100% sure you can grow with a lot cheaper light, but I have not spared a penny on this build, so I just bit the bullet and bought it. Again, much cheaper options that will grow algae for you, but after I watched the video above over the weekend, and saw the amount of time, effort BRS put into research, and saw the amount it grew in the same time, I just got the H380.

I use the H380 and I will say without a shred of doubt that it's one of the best purchases i've ever made

I bought the chaetomax LED since it was affordable and had good reviews. After about a month and a 12-hour photo period, the softball size chaeto has grown about 3-4 times the size.
