24/7 Mode
If you only need the aquarium light auto on and off, the 24/7 mode is quite suitable for you.

HG-978 18 IN







Power adapter

Input: 100-240V-0.5A 50/60Hz

Output: 20V-600mA

Besides, there are also some tips you should notice:
1. If you need to, you can long-press the second button to manually turn off the light.
2. Please keep the controller away from water as it is not waterproof.
3. Do not put the light underwater.
4. You need to reprogram the light if the power fails.

Next, let’s enjoy tutorial programming for two different modes.

DIY mode

On and off
On: Press the second button once
OFF: Long press the second button for about 3 seconds

Lighting time
Press the first button to choose the lighting time. There are three lighting times available – 6 hours, 10 hours, and 12 hours. You can choose one of the lighting times, for example, if you choose the ’10’ hours when you set the light at 7:30 am local time, it will turn off at 5:30 pm. The same as you choose the ’12’ hours.

Lighting color
Press the second button once, if the lighting color still is not what you want, please press the second button again or more once again. And there are seven colors available – full spectrum and six single colors which are red, blue, green, purple, cyan, and orange.

Lighting intensity
Press the third button once, if the intensity still is not what you want, please press the third button again or more once again. There are five level options – 10%, 25%, 50%, 75%, 100%. And if the intensity level is 10% at the beginning, as you press the button again and again, it will change from 10%, 25%, 50% to 100%, and then go from 100% to 10%. That is to say, if you choose the intensity level of 100%, and press the third button again, the intensity level will become 75%.

After you set the DIY mode, the light will memorize all the lighting time, color, and intensity automatically and auto-loop them every day until you reset it (you can unplug the light and replug it to reset).

24/7 mode

On and off
On: Press the second button once
OFF: Long press the second button for about 3 seconds

Time section
Press the fourth button to choose the time section for the embedded mode. For example, if it is 7:51 a.m. now, you can choose the time section ‘8:00’, and the light will run the 8:00 embedded mode. It will auto change to other modes when time goes to 10:00 am, 12:00, 15:00, 20:00, and 22:00. Finally, the light will shut off at 22:30. It’s convenient for aquarists who need to choose the special turn-on mode and don’t need to DIY other functions.

However, there is one tip for you. If you choose 24/7 Mode, the lighting color, intensity and time are automatic, and the timer will not work, you just need to set the time section, which means you do not need to set anything but the time section you need.

Notice that if you choose the 24/7 mode, the light intensity is the built-in default intensity and can’t reset.

    • Hello, Dave,
      You can get the light intensity to stay where you set it under DIY mode. It will go back to high intensity the next day when you set it under 24/7 mode.

      The followings are DIY mode programming steps:
      Lighting time setting: press the first button to choose from 6 hours, 10 hours, and 12 hours.
      Lighting color setting: press the second button to choose from seven available colors.
      Lighting intensity setting: press the third button to choose from 10%, 25%, 50%, 75%, and 100%.

      The light will auto-loop the mode and intensity every day after you set it.
