Hi everyone?

How do you measure light!
Some of my fluorescent are about 10 inches frome my phal, and some are about
6 inches.The brand of fluorescent is the Glow and Show, 20 inch long.
I would like to know if my phal are getting too much light or not enough but
I don`t know how to do it?


The best way is to use a light meter calibrated in footcandles.

Good ones aren't cheap.
