So, let’s get started with our complete guide to bearded dragon lighting, and help you create the perfect home for your reptilian buddy!

Key Takeaway

Providing the right types of lighting, including UVB lights, basking lights, and nighttime heating, is essential for bearded dragons’ health and well-being, as it helps them regulate their body temperature, synthesize vitamin D3, and absorb calcium.

Types of Lighting for Bearded Dragons

When it comes to lighting for your bearded dragon, there are three main types to consider: UVB lighting, basking lights, and nighttime heating. Each plays a specific role in your beardie’s overall well-being. Let’s dive into each type and see what’s best for your pet.

UVB Lighting

UVB lighting is essential for bearded dragons. These reptiles require exposure to UVB radiation to help them synthesize vitamin D3, which in turn, enables them to absorb calcium from their diet. Calcium is vital for healthy bone development, and without sufficient UVB exposure, your beardie can suffer from metabolic bone disease – a common yet preventable ailment in captive reptiles.

When choosing a UVB light for your bearded dragon, look for a high-quality, reliable brand. Some popular options include the Zoo Med ReptiSun 10.0, Exo Terra Repti-Glo 10.0, and Arcadia Desert 12%. These bulbs come in both linear fluorescent and compact fluorescent varieties.

Linear tubes are generally preferred, as they provide a more even distribution of UVB across the enclosure. Just make sure to choose a fixture that doesn’t block UVB with a plastic cover or glass, as these materials can filter out the essential UVB radiation.

Basking Lights

Bearded dragons love to bask, soaking up warmth to help regulate their body temperature. Basking lights are designed to provide a concentrated heat source, creating a warm spot for your beardie to enjoy. The ideal basking temperature for bearded dragons varies by age. Juvenile beardies need a basking spot around 100-110°F (38-43°C), while adult beardies prefer slightly cooler temperatures of 95-100°F (35-38°C).

There are many basking light options on the market, including incandescent, halogen, and ceramic heat emitters. Incandescent and halogen bulbs emit both light and heat, providing a visible basking spot for your beardie. Ceramic heat emitters, on the other hand, only produce heat and not light, making them a suitable choice for nighttime heating as well.

Nighttime Heating

While bearded dragons need a warm basking spot during the day, they also require a temperature gradient in their enclosure, including cooler nighttime temperatures. In the wild, bearded dragons experience a drop in temperature at night, and replicating this in captivity is important for their well-being. Aim for nighttime temperatures of 65-75°F (18-24°C) in your beardie’s enclosure.

To achieve this temperature range, you may need to provide supplemental heating, especially if your home gets particularly chilly at night. Ceramic heat emitters, as mentioned earlier, are a popular choice for nighttime heating because they emit heat without producing light, allowing your beardie to experience a natural day-night cycle.

Another option is an under-tank heater, which can provide gentle warmth without disrupting your bearded dragon’s sleep. Read more about under-tank heaters for bearded dragons in our guide!

Setting Up Bearded Dragon Lighting

Now that you know the types of lighting your bearded dragon needs, let’s discuss how to set them up in their enclosure for optimal results.

Placement of Lights

The placement of your lights is crucial for creating a comfortable and safe environment for your beardie. Here are some guidelines to follow:

UVB light: Mount the UVB light fixture inside the enclosure along the length of the tank, ensuring that it covers at least two-thirds of the enclosure. This will create a gradient of UVB exposure, allowing your bearded dragon to self-regulate their exposure as needed. The light should be positioned 10-12 inches (25-30 cm) away from your beardie’s basking spot to ensure they receive adequate UVB radiation.

Basking light: Place the basking light at one end of the enclosure to create a temperature gradient, with a warm basking spot at one end and a cooler area at the other. This allows your bearded dragon to thermoregulate by moving between the two zones. Make sure to place a basking platform, such as a branch or rock, directly under the basking light, so your beardie has a comfortable spot to bask.

Key Takeaway

Setting up your bearded dragon’s lighting involves proper placement of lights, creating a temperature gradient, and maintaining a consistent day-night cycle, ensuring that their enclosure mimics their natural habitat and promotes their overall health.

Regulating Light Schedule

Bearded dragons need a consistent light schedule to thrive. Aim for 12-14 hours of light during the day, followed by 10-12 hours of darkness at night. To ensure a consistent day-night cycle, consider using a timer for your lights. There are many reptile-specific timers on the market that can control multiple devices, making it easy to automate your beardie’s lighting schedule.

Monitoring and Adjusting Temperature

Keeping the temperature within the appropriate range is crucial for your bearded dragon’s health. Place two thermometers in your beardie’s enclosure: one near the basking spot and one at the cooler end of the tank. This will help you monitor the temperature gradient and make adjustments as needed.

If you find that the temperatures are too high or too low, you may need to adjust the wattage of your basking light or move the light fixture closer or further away from the basking spot. Remember, the goal is to create a temperature gradient that allows your beardie to regulate their body temperature as needed.

Light Maintenance and Replacement

Proper maintenance and replacement of your bearded dragon’s lights are essential for their well-being. Here are some guidelines to follow:

Replacing UVB Bulbs

UVB bulbs lose their effectiveness over time, so it’s essential to replace them regularly. Most UVB bulbs should be replaced every 6-12 months, depending on the manufacturer’s recommendations. Even if the bulb still appears to be working, its UVB output may have diminished significantly, putting your beardie at risk of inadequate UVB exposure.

Inspecting and Cleaning Light Fixtures

Regularly check your light fixtures to ensure they are functioning correctly and safely. Look for any signs of damage or wear, such as frayed wires, loose connections, or cracked ceramic sockets. Address any issues promptly to prevent accidents or malfunctions.

Cleaning your light fixtures is also important to ensure they continue to work efficiently. Dust and dirt can accumulate over time, reducing the light output and potentially causing overheating.

When cleaning your light fixtures, first unplug them and allow them to cool down. Then, gently wipe the surfaces with a soft, damp cloth to remove any dust or debris. Be cautious not to get any electrical components wet, as this can cause damage or create a safety hazard.

Common Questions

Are LED lights bad for bearded dragons?

LED lights are not inherently bad for bearded dragons, but they do not provide the necessary UVB radiation or sufficient heat for basking. If you choose to use LED lights for general illumination, you still need to provide a separate UVB light and basking light to meet your beardie’s specific needs.

Can bearded dragons live without UV light?

Bearded dragons cannot live without UV light, specifically UVB radiation, as it is crucial for synthesizing vitamin D3 and absorbing calcium from their diet. Insufficient UVB exposure can lead to metabolic bone disease, a painful and potentially fatal condition.

Can I use a regular light bulb for my bearded dragon?

You can use a regular incandescent light bulb as a basking light for your bearded dragon, as long as it provides the appropriate amount of heat. However, remember that a regular light bulb does not emit the necessary UVB radiation, so you will still need to provide a separate UVB light source.

Can you use a black light for bearded dragons?

Black lights, specifically those that emit UVA radiation, can be used for bearded dragons, but they should not be the primary source of lighting. UVA lighting can stimulate natural behaviors and improve your beardie’s overall well-being, but it does not replace the need for UVB lighting and a separate basking light.

How far should basking light be from bearded dragons?

The basking light should be positioned far enough from your bearded dragon to create a safe and comfortable basking spot. The ideal distance varies depending on the wattage and type of bulb used but generally falls within a range of 6-12 inches (15-30 cm) from the basking platform.
Monitor the temperature at the basking spot to ensure it stays within the appropriate range for your beardie’s age.

Do bearded dragons like natural sunlight?

 Bearded dragons do enjoy natural sunlight, as it provides the ideal source of both UVA and UVB radiation, as well as heat for basking. However, when exposing your beardie to natural sunlight, ensure that they have access to shade and do not overheat.
Never place your bearded dragon in a glass or plastic enclosure under direct sunlight, as it can quickly lead to dangerous overheating.


Proper lighting is key to keeping your bearded dragon healthy and happy. By providing the right types of light, creating an appropriate temperature gradient, and maintaining a consistent day-night cycle, you’re giving your beardie the best possible environment to thrive in.

Remember, regularly monitoring your bearded dragon’s lighting setup and making adjustments as needed is crucial. Keep an eye on the temperatures in their enclosure and replace their UVB bulbs as recommended by the manufacturer. With a little attention and care, your bearded dragon will enjoy a long, healthy life by your side.
