Of course I'm also not aware of which ones come full-spectrum.
I've had to temporally postpone the experiment due to a lightning storm that blew out more than half of the ballasts in my light fixtures. I'm still in the process of getting the fixtures back up and running.

This thread is only looking at linear fluorescent light bulbs.

Most light bulbs are not full spectrum as it requires a special type of quarts glass to allow the lower wavelengths to pass through (or no protective glass at all in the case of some HID lights) . This is one of the reasons why UV and full spectrum bulbs tend to cost more.
