UVB for Chinese Water Dragons (Physignathus cocincinus)

The right UVB lighting for healthy and active reptiles

The Chinese Water Dragon (Physignathus cocincinus) is a striking, diurnal lizard native to the tropical forests of Southeast Asia. Known for its vibrant green coloration and active behavior, this species has become a favorite among reptile enthusiasts. To keep your water dragon healthy and thriving, providing the correct lighting—especially UVB—is essential.

Why UVB lighting is so important

Like many reptiles, water dragons rely on UVB rays to synthesize vitamin D3, which is necessary for calcium absorption. Without it, they risk developing serious health issues like metabolic bone disease (MBD), muscle weakness, or growth disorders.

UV metal halide lamps – the best choice

Water dragons are very active and need lighting that covers both vertical and horizontal areas of their enclosure. UV metal halide lamps are ideal because they combine UVB, UVA, visible light, and heat in one bulb. This closely replicates natural sunlight and supports natural behaviors, strong bones, and overall vitality.

Our recommendation

We recommend 35-watt UV metal halide lamps mounted 30–40 cm above the basking spot. This provides the right intensity of UVB without overheating the animal. Combine this with proper ventilation and a lighting cycle of 10–12 hours per day for optimal health.

Conclusion

Proper UVB lighting is vital for your water dragon’s well-being. UV metal halide lamps are the most effective solution to simulate a tropical environment and ensure your reptile stays healthy and active.
