LED Aquarium Clip Light Energy Saving

This aquarium light is available in five sizes: 20 cm (3 W, suitable for 20–30 cm tanks), 30 cm (4 W, for 30–40 cm tanks), 40 cm (5 W, for 40–50 cm tanks), 50 cm (6 W, for 50–60 cm tanks), and 60 cm (7 W, for 60–70 cm tanks). All models are made from PP plastic, operate at DC 5 V, and feature a slim profile measuring 7.5 × 5.5 cm in cross-section. The 20 cm and 30 cm versions emit fixed blue and white light; the 40 cm, 50 cm, and 60 cm versions offer adjustable colour (red, green, blue, white) and brightness via a three-mode switch (white only; red + blue + green; red + blue + white + green). Power cord lengths are 1.5 m for the 20 cm and 30 cm models, and 2 m for the larger sizes. Weights range from 200 g (20 cm) to 500 g (60 cm). The clip-on design enables secure, tool-free mounting on aquarium rims of various thicknesses. The light spectrum supports healthy aquatic plant growth while helping suppress excessive algae formation — especially beneficial in planted or aquascaped tanks where light balance is critical. Its focused, bright output enhances natural colouration of fish and foreground plants without overheating the water or increasing evaporation. Ideal for small to medium freshwater aquariums, nano tanks, shrimp tanks, and aquascapes — particularly where precise lighting control, low energy use, and clean visual presentation matter most.
