Superfish Led Controller

Sunrise, sunset and autostart controller. Switch light automatic on and off at your desired times. Default setting, light on at 07.00 hour and off at 21.00 hour. Easy programming to personalise the time setting. The controller simulates natural sunrises and sunsets by dimming the lights over a period of your choosing. This allows your light to go from full brightness to off or off the full brightness over a 10 minute period. Allowing your fish to adjust to the change just as they would in the wild.
