hygger 36W Aquarium LED Light with 24/7 Cycle and DIY Colour Controls

The hygger 36W clip-on aquarium LED light is designed to illuminate freshwater tanks with a sunrise-to-moonlight daily cycle or customizable lighting, and fits tank walls less than 0.9 in (2.29 cm) thick.

• Automatic 24/7 cycle — moves through sunrise, daylight and moonlight, then switches off for the remaining hours.
• DIY controls — choose 6-, 10- or 12-hour timing, five brightness levels and color options.
• One controller for 2 or 3 lights — coordinate their brightness, color and spectrum mode.
• 36W output for long freshwater tanks of 30–60 gal (114–227 L) — sized for the stated tank range.
• 2835 and 5050 LED beads with a minimum 50,000-hour service life — the adapter separates from the light for replacement if damaged.
• Clip bracket with horizontal or vertical mounting — adapts to tank walls within the stated thickness limit.

Set a regular lighting rhythm for a freshwater aquarium or adjust the light to suit a planted landscape and changing display preferences. The hygger light offers an automatic day-to-night schedule as well as manual timing, brightness and color controls, with synchronized operation available for multiple lights.

What does the 24/7 mode do?

The default mode runs a gradual orange sunrise from 6 am to about 8 am, followed by gradual white light from about 8 am until 10 pm. Blue moonlight fades in from about 10 pm to 10:50 pm, and the light is off during the remaining hours. You can advance or delay the overall schedule to better match your preferred aquarium routine.

• Sunrise: gradient orange light.
• Daylight: gradient white light.
• Moonlight: gradient blue light, followed by an off period.

How can I customize the light?

DIY mode lets you select a lighting duration, brightness and color. Choose a 6-, 10- or 12-hour timer and one of five brightness levels, then select White, Red, Blue, Green, Purple, Orange or Cyan, or use Cycle Color. The controls also allow changes to the time, brightness and color rather than relying only on the automatic daily schedule.

• Color choices: seven named colors plus Cycle Color.
• Brightness: five available levels.
• Timer: three duration choices.

Will the clip bracket fit my tank?

The clip-style bracket fits tank walls less than 0.9 in (2.29 cm) thick, and the light body can be installed horizontally or vertically. The stated application is a long freshwater tank with a capacity of 30–60 gal (114–227 L). Measure the tank wall thickness before choosing this light.

The 36W unit uses 3 × 60 LEDs: 3 × 29 white, 3 × 11 blue, 3 × 4 red, 3 × 4 green and 3 × 12 RGB. Its white LEDs are 6500K; the blue, red and green LEDs are 455 nm, 620 nm and 560 nm respectively. The stated output is 3 × 770 lm, with CRI 3 × 85.

• Input: AC 100–240V; output: DC 20V.
• Power cord segments: 67.72 in (172 cm) + 1.97 in (5 cm) + 50.39 in (128 cm).
• Thickened aluminum body helps dissipate heat.

Can one controller operate multiple lights?

Yes, a single controller and harness can adjust the brightness, color and spectrum mode of 2 or 3 lights. This allows the lights to run in coordination, including a shared sunrise-and-sunset schedule, instead of requiring separate manual adjustments for each unit. The harness connects multiple lights through one controller, helping keep wiring together and reducing the number of power sockets used.

The light uses 2835 and 5050 LED beads and has a stated service life of at least 50,000 hours. Its soft output and color rendering close to natural light are designed to reduce discomfort associated with stroboscopic light for fish and viewers. The adapter is separable, so a damaged adapter can be replaced without replacing the entire light.

This hygger aquarium LED light suits freshwater keepers with a long 30–60 gal tank who want scheduled day-to-night lighting, adjustable color and brightness, or coordinated control across multiple lights. Its clip bracket, stated wall-thickness limit and 36W output define the fit for the intended tank setup.
