Build your own fluorescent light.
This is reflected on the fluorescent tube types with a three digit code three band fluorescents.

Well this is all about it.
Just attach the bulb ballasts plug it in.
4 x 15w black light uva fluorescent lamps with a peak of radiation at 350nm.
From scratch without buying light fixtures and taking them apart.
The usual types of fluorescent light sources used for growing plants are in the range of 6000k.

Here s how to build my faux flo ring light.
