New upgrade

This LED fish tank light is waterproof and easy to clean and wipe, so there is no need to worry even if it falls into the water briefly. With the separable adapter, there is no need to replace the whole light even if it is damaged. The extendable bending bracket can be adjusted in length and can be applied to various freshwater tanks. Thicken aluminum increases heat dissipation efficiency.

The fish light is soft, and the color rendering index is close to natural light, protecting eyes and fish, to refuse the discomfort caused by stroboscopic fish and viewers. Using high-quality 2835 + 5050 model lamp beads, it has a long service life of at least 50,000 hours.

Lighting time can be programmed to 6 H, 10 H, and 12 H. Lighting mode can be adjusted to 9 stages of brightness (10% – 25% – 50% – 75% – 100% – 75% – 50% – 25% – 10%).
