UVB Lighting for Corn Snakes – Which UV Lamp Is Suitable?

Corn snakes (Pantherophis guttatus) are among the most popular pet reptiles. While they are not strictly diurnal, they benefit significantly from appropriate UVB lighting in their terrariums. This guide explains why UVB is important for corn snakes and recommends suitable UVB lamps.

Why Do Corn Snakes Need UVB Light?

Although corn snakes can obtain vitamin D3 from their diet, UVB exposure offers additional health benefits:

  • Vitamin D3 Synthesis: UVB light stimulates natural vitamin D3 production, essential for calcium absorption and bone health.

  • Immune System Support: UVB exposure can enhance the immune system, promoting overall wellness.

  • Skin Health: UVB light has antimicrobial properties, helping to prevent skin infections.

  • Behavior and Coloration: Adequate lighting supports natural behavior patterns and may enhance coloration.

  • Circadian Rhythm Regulation: UVB contributes to a balanced day-night cycle, important for the snake's well-being.

Recommended UVB Lamp for Corn Snakes

We recommend a 35-watt UVB metal halide lamp, such as those from the Reptiles Expert HID series. These lamps provide a combination of UVB, UVA, and heat, simulating natural sunlight.

  • Optimal Distance: Position the lamp 30–40 cm above the basking spot.

  • Compact Option: For smaller setups, consider the 35W Mini UVB lamp, which offers the same benefits in a smaller form factor.

Alternative: UVB Compact Lamp

If space constraints prevent the use of a metal halide lamp, a UVB compact lamp is a viable alternative.

  • Installation Height: Mount the lamp 20–30 cm above the snake's preferred basking area.

  • Note: Ensure the lamp is not obstructed by glass or plastic, as these materials can filter out UVB rays.

Conclusion

Providing UVB lighting is crucial for the health and vitality of your corn snake. Whether you choose a 35W metal halide lamp or a UVB compact lamp, proper installation ensures your snake receives the necessary benefits.
