Is water lighting good for LED or good for energy-saving lamps?
You can also use a plant growth waterproof lamp, which allows plants to grow better depending on which plant has different spectra!
Is the use of LED, no energy-saving lamp with people, but also to use waterproof class, suggestions for the IP67 that is waterproof, can be soaked in water, some safety. Because LED's spectrum is complete.
I do not know to use energy-saving lamps to raise water plants, and how much watts light depends on what you want to raise grass
