Key Features
24-Hour Natural Light Cycle

- Prevents light shock and mimics the natural environment
- Helps regulate fish behavior and boosts plant photosynthesis
Fully Programmable & DIY Customization
- Two operating modes: Auto Cycle (default) and DIY Custom Cycle
- Set custom lighting schedules, color gradients, and intensity levels (In L7-L8, the light is blue, and cannot be changed, but the brightness can be selected)
- Auto memory preset saves your preferred light configuration (Memory function keeps local time in sync, remembers the programming of daylight/moonlight mode, and the DIY mode).
Full Spectrum LED with Adjustable Color & Brightness
- Offers 7 colors (red, purple, blue, cyan, green, yellow, white)
- 10 levels of brightness to meet specific plant and tank needs
- White daylight blends RGB LEDs for high PAR value, from 201(20W model) to 420.1(72W model)
- Moonlight mode includes gentle ambient colors for nighttime viewing
IP68 Water-Resistant & Durable Design
- Fully sealed aluminum housing resists splashes, humidity, and water intrusion
- Safe for aquarium use with low-voltage DC power
- No fan = no noise = long life and low energy bills
Smart Features for Effortless Use
- Auto ON at 6:30 am / OFF at 11:30 pm by default (adjustable)
- Includes built-in timer, auto shut-off, and power-loss memory function
- Easy setup: plug it in and place it on top of your tank—no extra programming needed
Versatile Mounting & Compatibility

- Ideal for freshwater aquariums, planted tanks, and aquascapes
Usage Tips
Enhance your aquascape and ensure optimal plant and fish health with these expert tips for using the hygger 957 aquarium light:
- Set Up the 24-Hour Natural Light Cycle for Stress-Free Environments
- Use Auto Mode to simulate natural sunrise and sunset transitions. This prevents light shock and mimics day/night rhythms, promoting calm behavior in fish and boosting plant photosynthesis.
- For best results, stick with the default ON at 6:30 AM and OFF at 11:30 PM, or customize your light schedule based on your tank’s needs.
- Customize Color & Brightness for Specific Plant Species
- Use DIY mode to select from 7 LED colors (under the Night mode) and 10 brightness levels.
- High-light plants (like Rotala, Monte Carlo, or Red Ludwigia) benefit from full-spectrum brightness (6500 K and more).
- Low-light plants (like Anubias, Java Fern, or Crypts) thrive with reduced intensity and red/blue combinations.
- Moonlight Mode creates a peaceful nighttime ambiance while letting nocturnal species stay active.
- Positioning for Maximum Coverage
- Place the fixture centrally above the tank for even light distribution across the substrate and water column.
- Adjust the mounting brackets to fit tanks 12–55 inches wide for secure and stable installation.
- Utilize Memory Function for Uninterrupted Lighting
- Power outage? No problem. The built-in memory function restores your last-used settings automatically—no reprogramming required, but the time needs to be reset after a power outage or unplugging.
- After the power is restored, the local time of the light will default to 12 noon if you don’t reset it; other settings remain unchanged, and then continue to run.
- Safe & Efficient Operation
- Never submerge the light—while IP68 water-resistant, it is designed for use above the waterline.
- Operate using low-voltage DC power for energy efficiency and long-term safety.
- No noisy fan = silent operation, ideal for tanks in bedrooms or offices.
- Long-Term Maintenance
- Gently wipe down the aluminum housing monthly to remove condensation or mineral buildup.
- Ensure the brackets remain tight and secure for stable positioning over time.
