The best UVB light for bearded dragons is the one that offers great heating and lighting output. 

Unfortunately, the markets are thick with all kinds of products, so choosing the right UVB lamp is a little trickier than it looks.

However, focusing on the following aspects can help you choose the right lamp for your bearded dragon’s tank.


Bulbs that have 50-100 wattage are best for heating the closure tank up to 33°-43° Celsius of your beardies.

Illuminating Bulb

Make sure the illuminating light source is suitable for providing your beardies with enough natural light.


UVB bulbs should at least work for 5-6 months. Because you must change the UVB bulbs every 6 months for effective temperature maintenance.

Attachment Clamps And Sockets

Look for tight and wide clamps that can hold the light in place once you attach it. The bulb sockets should be made to withstand high heating temperatures and not melt under the light.

Frequently Asked Questions 

Here are some frequently asked questions about the best UVB light for bearded dragons.

What Watt UVB Does A Bearded Dragon Need?

Your beardies are fond of living in desert areas with extreme temperature conditions. To provide a similar environment in its tank, any reptile bulb of high UVB wattage (50-100 watts) will be suitable.

How Often Should I Change My Bearded Dragon’s UVB Bulb?

For sage and better light exposure, it is ideal to change the UVB bulb in your bearded dragon tank every 6 months. UVB light is essential for providing your bearded dragon with the natural light that it lacks in its closed terrarium home.

Do Bearded Dragons Need UVB At Night?

Bearded Dragons need UVB at night as well, because their small bodies are built to bask in the heat. Without enough light exposure, they may develop various bone diseases.

What Happens If A Bearded Dragon Doesn’t Get Enough UVB?

Without enough heat and light, the reptiles develop calcium deficiency because they can’t get enough light to process Vitamin D3 minerals needed to form calcium in their bones. This may lead to serious metabolic bone disease.

How Do I Know If My Bearded Dragon Is Warm Enough?

Bearded dragons enjoy basking themselves in warm temperatures with their mouths slightly open. If the tank temperature is between 90° and 110° Fahrenheit or 33° and 43° Celsius, the bearded dragon changes its skin color to a nice warm yellow.

How can I tell if my bearded dragon is cold?

The ideal body temperature for a bearded dragon is usually 35° centigrade as it continuously basks in the light. If the dragon doesn’t get enough light, its body changes color to a dark brown shade, indicating that it doesn’t like the cold environment.

Bearded Dragon UVB Setup – What UVB lighting should be used?


So that’s it, folks. I hope this article has made you realize how important it is to only use the best UVB light for bearded dragons. Your bearded friend will love its tank if it has a nice heated environment.
