Hygger 18W 24/7 Lighting Aquarium LED Light for 18-24 Inch Fish Tank

This fish tank light features a 24/7 mode that can perfectly simulate the natural day and night cycle. It starts with a warm orange light at sunrise, transitions to a bright full spectrum light at noon, and ends with a starry blue light at nighttime. The start and end times can be customized to suit your exact needs. The light turns on and off slowly over a 15-minute period to avoid startling your fish.

The aquarium light also offers a DIY mode, allowing you to choose from 3 timer settings (6 hours, 8 hours or 10 hours), 9 customizable lighting colors (full spectrum white, red, green, blue, pink, purple, cyan, orange, and gradient), and 10 intensity levels (10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100%). This versatility lets your aquarium showcase its vitality and beauty in various lighting environments.

Equipped with premium 5050 RGB and 2835 lamp beads, the fish tank light features 5 rows of high-quality lamp beads. The 18W model, for example, has 90 LEDs: 47 white, 4 red, 3 green, 18 blue, and 18 RGB. Compared to ordinary lamps, the 5-row design provides wider and brighter illumination, with a luminance of 4065lx.

The aquarium light combines 6500K white, 460nm blue, and true 665nm deep red LEDs to efficiently maximize the photosynthesis of plants. With a Color Rendering Index (CRI) of over 90, it can restore the most accurate natural colors of fish and aquatic plants.

Constructed with a slim, sleek, and durable aluminum alloy body, this light fixture offers long-lasting performance. The 1.2mm premium aluminum shell provides effective heat transfer and a service life of up to 20,000 hours. The light body, without docking brackets, measures 18" L x 2.95" W, and its extendable bracket easily fits most 18-inch to 24-inch aquariums, making it easy to install on most glass or acrylic tanks with or without rims.
