I bought a six-pack of 4 ft. T8 LED lights from Amazon. I was just looking for a pair of them, but they were only sold in packs of six. The intent was to install them in my paint booth for badly needed illumination while priming. I wasn't sure what to do with the additional four lights, so I decided to install them on my storage rack.
The difference is very noticable. I thought I had enough lighting, but I'm really glad I put these up.
The other two lights will be installed on the PVC cross pieces in the spray booth. I'll cover them in thin plastic sheeting to keep them from catching any overspray.
