Usage Tips

  1. Installation & SetupSecurely mount the light on the tank rim using the sliding brackets, adjusting the length and angle for even light coverage across the aquascape.
    Position the light at an appropriate height above the water surface to optimize light penetration and shimmer effect without causing excessive heat or algae growth.
  2. Selecting Lighting ModesUse the Default 24/7 Natural Mode to simulate a realistic day-night cycle that supports fish circadian rhythms and natural plant photosynthesis.
    Switch to DIY Mode for customized lighting schedules, choosing from 6, 10, or 12-hour durations, seven vibrant colors, and five brightness levels to meet specific aquatic needs or aesthetic preferences.
    Regularly monitor and adjust brightness settings to balance plant health and prevent algae overgrowth.

  3. Timing & AutomationPair the light with a timer or smart plug for reliable, automated on/off cycles, reducing manual intervention and ensuring consistent lighting for your aquarium ecosystem.
    Recommended lighting duration for planted tanks is typically 8 to 10 hours per day, adjusting based on plant species and tank conditions.
  4. Maintenance & CleaningAlways unplug the unit before cleaning or adjusting the fixture.
    Use a soft, dry cloth to wipe the light surface and brackets regularly to prevent dust and water residue buildup.
    Avoid exposing the light’s internal components or adapter to water or moisture, even though it has a waterproof rating.
    The separable adapter design allows for easy replacement or servicing without changing the entire unit.
  5. Heat ManagementEnsure proper ventilation around the light fixture to maintain efficient heat dissipation via the aluminum housing and silent cooling fan.
    Do not block airflow around the light to prevent overheating and prolong the device’s lifespan.
  6. Optimize Plant and Fish HealthAdjust the light intensity and color based on the types of aquatic plants and fish species in your tank for best results.
    For sensitive or low-light plants, use lower brightness or softer color settings; for demanding high-light plants, increase brightness and utilize full-spectrum white light.

Beautiful light allows me to see my hermit crabs in a natural setting. This light is sturdy and is easy to mount on the tank. The timer function was surprisingly configurable and might have been very complicated if it weren't for the 24h mode button. This convenient button sets up the light with a preset 4 stage (dawn, daylight, dusk, nighttime) light timer with an extended daylight time. I deducted one star for the difficult-to-understand manual. But if you choose the 24h mode as I did, the only truck is the one-time setting of the timer to the current time setting; one of 08:00, 10:00, 12:00, 15:00, 18:00, or 22:00.

  1. I love these lights! The 24hr setting is great for my cichlid tanks. I’ve bought these for 3 different tanks. I have 2 set up, one on a 125 gallon that works great, even though it doesn’t span the entire 6ft of the aquarium. It used to be on my 75 gallon before upgrading. I also have one on my 25 gallon aquarium, and one on the way for a 10 gallon grow out tank.

  2. This fish tank light looks great! I really like the smooth, flat top—it not only looks sleek but will also be easy to keep clean. The light is very bright but adjustable, which is a big plus. Setup was quick and easy, and the controls are simple and user-friendly. Overall, it’s a great light, especially for the price. Highly recommended!

  3. This light is awesome! Not only are you able to slide the clip into the shorter side, but also the long side of the light which makes it adaptable to different types of aquariums but styles you want as well! My first one came in with a malfunction, but Hygger quickly replaced it for me, and did not have me return the other. 10/10!

  4. I have been loving this aquaium light. I really like how you could set the 24 hr mode and leave it be. No need to turn on lights as it will do it all automatically. I am converting all my tanks to these lights. I just wish they had a 72″ version of this one.

  7. This light is replacing another that wasn’t working out so well. The other “clipped” on to one side of aquarium and was really distracting because it had to be tilted to light whole aquarium. This light however sits in middle of aquarium and lights the whole thing. I have a 29 gallon and it fits perfectly. The rails slide out so it is very adjustable. It’s fun to watch the reaction of the fish when I turn on the different colors of lights. Sits close to glass top. Would definitely recommend.
