You can use that old 35 mm camera that you never use since you bought
your digital camera! It needs to be a camera you can set the F stop on
as well as the ISO setting for the film. The Ortho book on orchids has
the information on how to convert the result into foot candles.

We tried a model (about $50) from Charley's, the results were so obviously
inaccurate we never used it. Kenni

I use a digital one from Phytotronics and have had it for years. No need
to give a model number (PLM) cause it is most likely discontinued. Hanna
also makes some good ones. Avoid analog ones such as the GE as they slowly
will get out of calibration and you will not know it or have the means to
recalibrate it. Plan to spend over $100, I have never found a cheap model
that is anything but trouble. Things to look for in light meter; uses
common batteries, water tight, protective boot, reads in foot candles,
light source option, maximum light reading.

Another tool that you might consider is a meter that measures light
from various sources--daylight, HID, and flourescent. It was a real
eye-opener for me--I didn't have nearly as much light as I thought I
had.

Could someone recommend a good light meter?
