comfortably numb
its been re-scaped since i took this pic but the lighting is the same

how i do my lights is , ive got 2 tubes as the main light and the blue leds. duringh the day both tubes are on then in the evening i switch off 1 of the tubes a couple of hours after that i switch on the leds and turn off the other tube. then when i go to bed switch off the leds. in the morning i do the same process but in reverse. so that the level of light gradually fades then gradually gets stronger. it seems to work quite well.
ok thanksits just a little strip of blue leds with a plug on the end . completely waterproof can be used either on top of tank or submerged
