Hygger HG978 24/7 Extendable LED Aquarium Light

Hygger HG978 24/7 Extendable LED Aquarium Light

Full-spectrum planted-tank lighting with a natural day/night cycle and flexible DIY control.

The HG978 sits across the aquarium on extendable metal brackets—it is not a clip-on light. Its slim aluminium body provides even coverage for freshwater displays and planted tanks from 18 to 54 inches, depending on the selected wattage.

Lighting modes

• Natural 24/7 cycle: gradual sunrise, daylight, dusk and moonlight transitions.
• DIY mode: choose a 6, 10 or 12-hour lighting period, seven colour options and adjustable brightness.
• Full-spectrum output: white and RGB LEDs bring out fish colour and support live plants.
• Durable construction: thickened aluminium housing improves heat dissipation; the separable adapter is easy to service.
• Extendable brackets: stable support across rimmed or rimless aquariums.

Choose the correct size

Care tip: begin with a shorter photoperiod and moderate brightness, then increase gradually while monitoring plant growth and algae.
