hygger Full Spectrum Aquarium LED Light, 22W Clip-On with Programmable Day-Night Timer

The hygger 22W clip-on aquarium LED light provides programmable day-and-night lighting for fish and planted tanks, with 120 LED beads and nine color options.

• Daylight, moonlight, combined, and manual modes — choose a lighting schedule to suit your tank routine.
• Sunrise-to-sunset daylight transitions — shift from gradient orange to full-spectrum white and back to gradient orange.
• Moonlight settings include seven colors and six brightness levels — adjust the nighttime appearance of your aquarium.
• Clip bracket fits tank edges under 0.74 in (1.88 cm) thick — attach the light to compatible aquariums.
• Splicing combinations can light tanks up to 60 in (152.4 cm) long — extend coverage for extra-long tanks.
• Separable adapter and extendable positioning rod — replace the adapter separately if damaged and adjust the light’s position over the tank.

Keep a consistent lighting routine for an aquarium with a programmable light that offers separate daylight and moonlight settings. The hygger light is made for fish tanks and planted aquariums, with a clip-on bracket for compatible tank edges and an adjustable rod that lets you move the light position back and forth. Its timer options cover daylight, moonlight, or both, while manual mode lets you operate the light without a preset schedule.

What lighting modes and timer options does the hygger aquarium light offer?

The hygger light has four operating modes: daylight, moonlight, combined daylight and moonlight, and manual. In daylight mode, choose a 6H, 10H, or 12H duration; the light transitions from gradient orange through full-spectrum white and back to gradient orange. Moonlight mode offers 3H, 5H, or 12H timing, six brightness settings from 10% to 100%, and seven colors: red, orange, yellow, green, cyan, blue, and purple. Select both daylight and moonlight to use the two lighting periods together.

• Daylight timer choices: 6H, 10H, and 12H.
• Moonlight timer choices: 3H, 5H, and 12H.
• Moonlight brightness choices: 10%, 25%, 35%, 50%, 75%, and 100%.

Will the clip and light length fit my aquarium?

The clip bracket is designed for aquarium edges less than 0.74 in (1.88 cm) thick, and the 22W light is intended for tanks 25 in (63.5 cm) to 31 in (78.7 cm) long. The extendable rod moves the light back and forth so you can adjust its position over the tank. For an extra-long aquarium, compatible hygger lights can be spliced together: the 14W + 42W combination and the 22W + 26W combination each support tanks up to 60 in (152.4 cm) long. Other combinations are also possible.

• Measure the aquarium edge to confirm it is under 0.74 in (1.88 cm) thick.
• Use the 22W model for the stated 25 in (63.5 cm) to 31 in (78.7 cm) tank-length range.

What are the LED and electrical specifications?

The hygger 22W light has five rows of 2835 and 5050 LED beads, with 120 LEDs in total: 70 white, 14 blue, 8 red, 4 green, and 24 RGB. Its color rendering index is 82.5, and its output is 2291 lumens. The listed color specifications are white at 6500K, blue at 455nm, red at 620nm, and green at 560nm. The light uses a thickened aluminum construction to increase heat dissipation efficiency; the LED beads have a stated service life of at least 50,000 hours.

• Electrical input: AC 100–240V; output: DC 20V.
• Power cord lengths: 4.9 ft (1.49 m) and 2.3 ft (0.70 m).
• The five-row light is designed for soft illumination and to reduce stroboscopic discomfort for fish and viewers.

This light suits aquarium keepers who want timed daylight and moonlight options, adjustable color and brightness, or an extendable setup for a longer tank. Its edge-thickness and tank-length limits help identify compatible aquariums, while the separable adapter means an adapter can be replaced without replacing the complete light if it is damaged. The hygger clip-on light combines programmable lighting with a fit range for compatible fish and planted tanks.
