Well what are you using for a sump? Concur better lighting would be benificial, but not needed for the pods
and if you have a good daylight bulb the plants should grow as well.
When you say sump are you referring to the entire thing or do yo actually have a fuge area in the sump? Without the plants there really is not need to light a sump at all. If you are runnign afuge for the purpose of growing plants to reduce nitrates then of course you want some lighting.
