UV strictly speaking, covers a wide range of wavelengths. In the trade, we actually extend this into the visible.
With DE bulbs, we add UV shielding, but what wavelengths are we shielding? The atmosphere effectively cuts off light around 300nm. Pyrex also happens to cut off at about 300nm and is thermally stable. Is this what is used?
What is considered safe for corals? >300nm? >350nm? >400nm? etc.
