Bearded Dragon Light Schedule Guide

Complete Bearded Dragon Light Schedule Guide

If you’re a proud bearded dragon owner, you’ll want to ensure your scaly friend is comfortable and healthy in its environment.

One crucial aspect of creating a suitable habitat for your bearded dragon is establishing a proper lighting schedule. In this comprehensive guide, we’ll discuss the importance of proper lighting, the types of lighting you should use, and how to create the perfect light schedule for your bearded dragon.

Light TypeDurationFrequency
UVB Light10-12 hoursDaily
Basking Light10-12 hoursDaily
Nighttime Heat Light0-12 hours (depending on temperature)Nightly

It’s important to note that bearded dragons require a UVB light to help them produce vitamin D3, which is essential for their bone health. The basking light provides heat for the dragon to thermoregulate and digest its food properly.

Importance of Proper Lighting

To keep your bearded dragon healthy and happy, it’s essential to provide adequate lighting. Here’s why:

UVB Exposure

Bearded dragons require exposure to ultraviolet B (UVB) light to synthesize vitamin D3, which is necessary for calcium absorption. Without sufficient UVB exposure, your bearded dragon may suffer from metabolic bone disease, which can lead to deformities and other health issues.


Bearded dragons are ectothermic, which means they rely on external heat sources to regulate their body temperature. A proper light setup provides the heat they need to maintain optimal body temperature, digest food, and remain active.

Day and Night Cycles

Just like humans, bearded dragons need a regular day and night cycle to maintain proper sleep patterns and overall health. A consistent light schedule mimics their natural environment, ensuring they remain healthy and stress-free.

Types of Lighting

There are three main types of lighting you should consider for your bearded dragon’s habitat:

UVB Lights

As mentioned earlier, UVB lights are crucial for your bearded dragon’s health. When choosing a UVB light, look for one that provides an output of 10-12% UVB. Replace these bulbs every six months to ensure consistent UVB exposure.

Basking Lights

Basking lights provide the heat your bearded dragon needs to regulate its body temperature. These lights should create a basking spot with a temperature between 95-110°F (35-43°C), depending on your bearded dragon’s age and size.

Infrared Lights

Infrared lights can be used during nighttime to provide supplemental heat without disrupting your bearded dragon’s sleep cycle. These lights should only be used if the nighttime temperature drops below 65°F (18°C).

Creating the Perfect Light Schedule

To create a comfortable and healthy environment for your bearded dragon, follow these guidelines for daytime and nighttime light setups:

Daytime Setup

During the day, both UVB and basking lights should be on for 12-14 hours. This schedule mimics the natural daylight cycle in the wild and promotes proper sleep patterns. To ensure consistency, use a timer to automate the on and off times for your lights.

Nighttime Setup

At night, turn off both the UVB and basking lights. Your bearded dragon needs complete darkness to get a good night’s sleep. If the temperature in your home drops below 65°F (18°C) during the night, you can use an infrared light or a ceramic heat emitter to provide supplemental heat without disrupting your bearded dragon’s sleep.

Common Mistakes to Avoid

When setting up your bearded dragon’s lighting, make sure to avoid these common mistakes:

  1. Placing UVB lights outside the enclosure, as the mesh or glass can block UVB rays.
  2. Using coil or compact UVB bulbs, as they don’t provide consistent UVB exposure.
  3. Relying on heat rocks or pads, which can cause burns and don’t allow for proper thermoregulation.

Signs of Inadequate Lighting

If your bearded dragon isn’t receiving proper lighting, it may exhibit the following signs:

  1. Decreased appetite or weight loss
  2. Lethargy or inactivity
  3. Abnormal sleeping patterns
  4. Difficulty shedding or retained shed
  5. Weakness, tremors, or seizures (signs of metabolic bone disease)

If you notice any of these signs, evaluate your lighting setup and make necessary adjustments to ensure your bearded dragon is receiving adequate lighting.

Adjusting the Light Schedule for Your Bearded Dragon’s Needs

As your bearded dragon ages or during seasonal changes, you may need to adjust the light schedule to meet its changing needs.

For example, during winter months, you might reduce the daytime light duration to mimic shorter days. Similarly, as your bearded dragon grows, you may need to adjust the basking spot temperature to accommodate its size and age.

Frequently Asked Questions

How often should I replace my bearded dragon’s UVB light?

Replace your bearded dragon’s UVB light every six months to ensure consistent UVB exposure.

What should the basking spot temperature be for my bearded dragon?
