Led blues for an aquarium. Lights on 7:30am off 6-8pm time of year pending. For a good day time pic we tickle their little bums with a leaf till they wake up lmao. Night time i turn their uvb bulb back on because its a fairly dim bulb compared to the 65k's i have everywhere. Our 3 are fully active by 10pm and hunker in just before 7am
