Really depends if you use hops or not. I always put a few pellets in for thier antimictobial properties.
And it depends when and how you pitch your starters.
Light + hops would be bad If your starter is just to reduce lag time ie pitching it at high krausen. While this is common it's mostly of those that have never tasted a starter and ignorantly add all those bad phenols and esters to thier beer when pitching.
Your starter has only one real purpose, to grow healthy yeast in an amount for a proper pitch. Yeast health is the most important thing. You shouldn't care what phenols and esters it makes. Then you decant and only pitch the yeast not the starter liquid. In this case light doesn't matter.
