hygger Submersible Aquarium LED Light, 19-Inch 17W, 24/7 Mode and IP68 Waterproof

Hygger’s 17W submersible aquarium LED light is made to illuminate fish tanks 20–35 in (50.8–88.9 cm) long, with five rows of LED chips and a 24/7 lighting mode.

• 19 in (48.3 cm) light for 20–35 in tanks — choose it for aquariums within the stated length range.
• Five rows of LED chips — illuminate the tank with a 120-LED full-spectrum array.
• IP68 waterproof rating — place the light fully underwater or attach it inside the tank.
• 24/7 lighting mode with a gradual 15-minute transition — move between daytime and evening light more slowly.
• Nine color choices, 10 brightness levels and five timer settings — adjust the light to your preferred setup.

For aquarium owners who want to light a tank from within the water, this Hygger LED strip combines a submersible design with adjustable color, brightness and timing. Its full-spectrum RGB LEDs are designed to bring out the colors of fish and aquatic plants, while the daily-cycle mode changes the lighting gradually rather than switching abruptly.

What lighting options can I choose?

The light offers a 24/7 mode that moves through warm morning light, a brighter midday spectrum and soft blue evening light. It opens or closes gradually over 15 minutes, a feature designed to help prevent light shock to fish. For a customized setting, choose from nine colors and 10 brightness levels.

• Colors: white, red, blue, green, pink, purple, orange, cyan and cycle color.
• Timer settings: 4, 6, 8, 10 or 12 hours.
• Control options include TIMER, brightness (+/−) and M keys.

Can the Hygger light be placed underwater?

Yes. Its IP68-rated sealed design allows full submersion, and the light is made to operate underwater without generating water vapor. Two suction cups secure it inside the aquarium, including at the top or bottom, so you can position the strip where you want the light.

• Power: 17W; input: AC 100–240V; output: DC 20V.
• Power cord sections: 6 ft (1.83 m) and 4.8 ft (1.46 m).
• The product parameters give an illuminance of 4889 lx and CRI of 89.

What LEDs and light spectrum does it use?

The 19 in (48.3 cm) strip uses 2835 and 5050 model LED beads, with at least 50,000 hours of service life. The 120 LEDs comprise 40 white, 24 blue, 4 red, 4 green and 48 RGB LEDs. White light is 6500K, blue is 455nm and red is 620nm.

• Five rows of LED chips create the light array.
• Full-spectrum RGB LEDs display the colors of fish and aquatic plants.

This light suits aquarium owners with a 20–35 in (50.8–88.9 cm) tank who want an underwater fixture and control over lighting color, brightness and duration. Its size range, submersible IP68 design and selectable lighting modes make it a fit for that setup.
