Unless your darkroom is light at least 8 hours per day and uses a lot of UV, there is NOTHING in a developer solution that is overly light sensitive. You would have to BLAST it with high intensity light to cause a problem with keeping the developer around.

The big problem is AIR. Oxygen and Carbon Dioxide are your enemies.
