Bearded Dragon Basking Under Bulb

Why Do Bearded Dragons Need UVB Light?

UVB light bulbs are one of the most important parts of setting up your beardies habitat. Without this key component, the risk of health concerns greatly increases.

Bearded Dragons need UVB to synthesize the vitamin D3 production in their skin. Vitamin D3 metabolizes calcium which encourages healthy growth.

Complications with their diet can occur when your Bearded Dragon has no UVB exposure, leading to health concerns such as metabolic bone disease.

What Is Ultraviolet Light? (UV)

Ultraviolet (UV) light is a form of electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays. For Bearded Dragons, UV light is crucial for their health, and it can be categorized into three subtypes based on wavelength:

UVA (320-400 nm): UVA, often called “black light,” is important for Bearded Dragons as it helps regulate their circadian rhythm, allowing them to distinguish between day and night. Adequate UVA exposure contributes to their overall well-being.

UVB (280-320 nm): UVB is essential for Bearded Dragons as it enables the synthesis of vitamin D3 in their skin. Vitamin D3 is crucial for calcium metabolism, which is vital for bone health. UVB exposure helps prevent metabolic bone disease, a common health issue in reptiles.

UVC (100-280 nm): UVC has the shortest wavelength and is the most energetic, but fortunately, it is absorbed by the Earth’s atmosphere and doesn’t reach the surface. Bearded Dragons do not have direct exposure to UVC in their natural habitat.

Ultraviolet Light Table

When we discuss “NM” on the table, it stands for nanometers, the unit of measurement for wavelength. For example, when we mention the UVA range of 320-400 nm, it means the UVA radiation for Bearded Dragons falls within this range of 320 to 400 nanometers.

Understanding the specific wavelength ranges is crucial for Bearded Dragons because it influences how they benefit from UV light. For instance, exposure to the appropriate levels of UVA helps regulate their behavior and activity patterns, while UVB is essential for maintaining proper calcium levels in their bodies.

What to Look For When Buying A Bearded Dragon UVB Light Bulb?

Below is a list of what you need to look for when buying a UVB light for your Bearded Dragon.

UVB Output Efficiency

Measure the bulb’s UVB output as a percentage of its total energy consumption. Use specifications provided by the manufacturer and compare them with standard benchmarks in reptile care.

Spectrum Quality

Evaluate the spectrum of light emitted by the bulb, focusing on the range that’s beneficial for Bearded Dragons. Use manufacturer data and any available spectral analysis from third-party reviews.

Bulb Lifespan

Assess the average lifespan of the bulb as claimed by the manufacturer, and compare it with user experience to verify these claims. Longer lifespan bulbs are generally more desirable.

Compatibility and Ease of Installation

Evaluate how easily the bulb can be installed in common terrarium setups, using information from the product specifications and user experience.

Price and Value for Money

Compare the cost of the bulb against its features and performance. This can be a ratio or a comparison against the average price of similar bulbs in the market.

Energy Efficiency

Assess the energy consumption of the bulb compared to its output. Lower energy consumption for the same output is preferable.


FAQ

Can Bearded Dragons Get Too Much UVB?

Yes, Bearded Dragons can receive too much UVB exposure. You should follow 12 hours-on and 12 hours-off cycle to optimize your beardies UVB exposure for their overall health.

How Long Can A Bearded Dragon Survive Without UVB?

Bearded Dragons should never go longer than 2 days without being exposed to UVB. They may survive longer but the long-lasting effects of the lack of UVB can lead to sickness and fatalities.

Is T5 Or T8 Better For Bearded Dragons?

T5 UVB lights are recommended for Bearded Dragons due to their higher output and newer technology. However, T8 UVB lights are still good for certain setups, for example, T8’s come in a tube shape and provide more coverage in the tank.
