I know what white light is. When I compared the growth rates on white LEDs with blue or red, the difference was negligible. I run bigger systems so power use is important to me, but my results with 100W "white" puck were as good as 100W red led matrix.... same algae weight (and yes, I weighed the batches).

The algae was different, by the way. The white side was darker green and had more variety - red, purple, etc... but weight was ~ the same.

I found that flow and media had a lot more impact.
