- Mount the light to your aquarium using the built in gooseneck mount. Secure the screws firmly, but do not over-tighten them.
- 2 Plug the power supply into your light, then plug the power supply into the wall, in that order.
- 3 Press the power button to turn your light on or off.
- 4 Adjust the intensity and color spectrum by pressing A or B. Each press changes the output by 10%.
- 5 If desired, set the timer to 8, 10, or 12 hours by pressing the clock icon, 1, 2, or 3 times. Make sure you set this at your desired on time. The light will automatically run for the prescribed time each day. For example, if you set your light to 8 hours at 9AM, it will shut off at 5PM, then turn back on at 9AM the next day.
