Bearded Dragon Lighting, Heating & Humidity Requirements - bearded dragon in a tank habitat

Creating the perfect environment for your bearded dragon is crucial for its health and happiness. Let’s dive into the essential requirements for lighting, heating, and humidity to ensure your scaly friend thrives in its new home. Bearded dragons have specific needs that mimic their natural habitat, and we’re here to guide you through setting up the ideal tank conditions.


Proper lighting is vital for bearded dragons, as it helps them regulate their body functions and synthesize essential nutrients. Here’s what you need to know:

  • UVB Lighting: Essential for vitamin D3 synthesis and calcium absorption
  • Use a UVB fluorescent tube with 10-12% output
  • Replace the UVB bulb every 6 months to ensure effectiveness
  • Provide a basking lamp for heat, maintaining a temperature of 95-100°F
  • Maintain a 12-14 hour light period followed by 10-12 hours of darkness

Remember, the right lighting setup is crucial for your bearded dragon’s overall health and well-being. It helps prevent metabolic bone disease and ensures proper growth and development.

Heating: Creating the Perfect Temperature Gradient

Bearded dragons are ectothermic, meaning they rely on external sources to regulate their body temperature. Here’s how to set up the ideal temperature zones in your dragon’s tank:

Temperature Zones for Bearded Dragon Tanks

  • Hot side: 95-110°F (35-43.3°C)
  • Cool side: 75-85°F (23.9-29.4°C)
  • Basking spot: 100-110°F (37.8-43.3°C)
  • Daytime ambient: 75-85°F (23.9-29.4°C)
  • Nighttime: up to 70°F (21.1°C)

To achieve these temperature ranges, use a combination of heating devices:

  • Basking lamp for the hot side and basking spot
  • Ceramic heat emitter for overall ambient temperature
  • Undertank heating pad for additional warmth (optional)

Always use thermometers to monitor temperatures accurately and adjust as needed. A thermostat can help maintain consistent temperatures and prevent overheating.

Humidity: Balancing Moisture Levels

While bearded dragons come from arid environments, they still need some humidity for proper shedding and hydration. Here’s what you need to know about maintaining the right humidity levels:

  • Ideal humidity range: 30-40%
  • Use a hygrometer to monitor humidity levels
  • Mist the enclosure lightly once or twice a week
  • Provide a shallow water dish for drinking and soaking

Be cautious not to create an overly humid environment, as this can lead to respiratory issues and other health problems.
