This is why my shrimp tank has two lights: an otherwise useless Marineland single bright LED suspended above the shelf all my small tanks are on for general viewing and small powerful LED on the tank itself for the plants. The single bright can be on anywhere from 6-16 hrs, the dedicated light for only 4-6.
