[Aavso-photometry] Are there good internet plans for light boxes?

[Donn Starkey]

Richard:

There is an interesting and low cost version of a fluorescent powered light
box from the web site Calvin College at:
http://www.calvin.edu/~lmolnar/calobs/equipment/flat.html

The fluorescent light has a toe at the blue end of the spectrum where many
of the incandescent lamp based boxes output largely in the longer
wavelengths.
