The Sobo AL-380 is a 15.5W COB full-spectrum LED aquarium light built for planted tanks 40–50 cm long, delivering bright, even light that drives healthy plant growth and brings out vivid fish and plant colour. It uses Chip-on-Board (COB) LED technology in a slim aluminium body that rests across the tank on adjustable brackets for strong, even penetration.

Specifications

Which tanks is it best for?

The AL-380 is the primary light for planted aquariums 40–50 cm long, giving enough intensity for low- to medium-light plants like Anubias, Cryptocoryne, Java fern and easy stem plants, and excellent display light for tropical fish-only tanks. Step up to the Sobo AL-480 (50–60 cm) for larger tanks, or down to the AL-180 (20 cm nano) for smaller ones. For plant selection by light level, see our planted aquarium lighting guide.

How to use it

Mount the light across the tank on its brackets and run it 7–8 hours a day for a planted tank, on a timer for consistency. Always include a dark night period and keep the tank out of direct sun to avoid algae. A glass or acrylic canopy between the light and water protects the unit from moisture and extends its life.
