What will they think of next

Looks flashy (sorry for the pun) but it's not hard to do. Especially on a larger fixture where banks of LEDS are driven by separate driver circuits. Just flash each circuit in order down the tank and you have simulated lightning. The programming should be very simple once you already have a controller in the system.

To me it's more a gimmick. I doubt it has any benefit to the livestock and may actually startle and stress fish. Personally I would never use it.
