Why Bearded Dragons Need UVB

Bearded dragons need UVB to keep healthy. For example, UVB helps the reptile produce vitamin D, calcium and develop strong bones.

After 12 months without an adequate source of UVB (and even with supplementation for some species), a very large percentage of reptiles develop the metabolic bone disease.

The disease presents with different symptoms depending on the severity of the situation. These might include:

Factors to Consider When Buying a UVB Lamp

A bearded dragon’s lighting setup should mimic the wild as closely as possible. Choose a lamp that provides greater coverage for the enclosure.

If you use a standard UVB bulb for a huge enclosure, it will not provide enough UVB heat.

The UVB Should Cover the Bearded Dragon Whenever It Goes

Bearded dragons will benefit if the lighting covers at least two-thirds of the tank. So, choose a busking bulb that will UVB wherever they go.

Linear lighting is a popular choice because it covers most of the tank. This mimics the wild where the sun is everywhere.

If you are using a coil UV light make sure that they are multiple spanning across the tank.

Also, have a solar reader to ensure they are putting out the correct lighting. However, it is cheaper to use UV light.

Change the Light After Six Months

Even if you have bought a good quality bulb, after six months, it may get weaker. As a result, your bearded dragon might not get enough UVB.

If not, the bulb could provide too much heat, which could be harmful to your bearded dragon.

Positioning the UV Light Correctly

You can place the lamp on top of the tank, outside the tank, or inside the tank. However, it is ideal to put it inside the tank.

Do not place a barrier between your reptile and the light. Any screen will filter out some UV lights from reaching the bearded dragon.

If you have a mesh, choose a busking bulb with high output so that it can penetrate the tank better.

Or you can put it on top of the tank if your tank is uncovered. Don’t put it on top of the glass. Glass filters almost 100% of UVB rays.

Most bulbs come with a chart showing how far your beardie should be from the bulb.

You need to position it in a place where the bearded dragon can get closer or further away from it.

Don’t put it too close or far from the bearded dragon. Your reptile might be getting dangerous amounts of heat.

Although bearded dragons can regulate their heat, sometimes they might not be able to.

If your UV light is far from the tank, the bearded dragon might not be getting all the lighting that it needs.


When buying busking bulbs for bearded dragons, you want to balance affordability with great heat output. Even though the options are many, this guide provides some of the best basking bulbs for bearded dragons you can find in the market.
