Need For a Heat Lamp for Bearded Dragon

Bearded dragons are semi-arboreal creatures belonging to the reptilia class in the animal kingdom.   

Like all reptiles, bearded dragons are cold-blooded, which means they depend on their environment to regulate their body temperature. This is why a bearded dragon’s enclosure needs to have spaces for both hotter and cooler temperatures as per their needs.  

Along with this, bearded dragons are originally from hot and arid desert regions. In a natural environment, bearded dragons bask in the sunlight to get UVB exposure for absorbing calcium and vitamin D3. This ensures that they do not get any critical illnesses like metabolic bone disease. 

Providing a heat lamp also ensures that there is no excess build-up of moisture in the terrarium and that your bearded dragon does not get any fungal or bacterial infections. 

You need to ensure that in a pet enclosure, your bearded dragon gets sufficient heat and light which imitates their natural environment. 

It is therefore crucial that you invest in a good quality heat lamp so that your bearded dragon stays healthy and all its basking requirements are met.  

Key Factors to be Considered While Buying a Heat Lamp

While buying a heat lamp for your bearded dragon you should take into account the following factors:

Does the Heat Lamp Provide Both Heat and Light?

Bearded dragons need UVA and UVB lighting, and heat in the pet enclosure. 

UVA light is crucial for your pet’s good eye health whereas UVB light helps in the absorption of vital nutrients like calcium and vitamin D3. 

This will help keep your pet bearded dragon in optimum health and have a longer lifespan. 

What is the Wattage of the Heat Lamp?

As a general rule of thumb, the higher the wattage of the bulb, the more heat it will emit. Remember, you need to buy a bulb with a wattage within a range of 50-150 watts depending on how large the pet enclosure is. 

The overall temperature of the pet enclosure should be around 90-93 degrees Fahrenheit (32-34 degrees Celsius).  

Along with this, you must also take into account the general distance of the heat lamp from your bearded dragon. 

It is always safe to begin with a heat lamp of 50-80 watts if you are a complete newbie. You can then monitor the ambient temperature of the pet enclosure and change the bulb having a higher wattage accordingly.

Is the Heat Lamp a Right Fit?

Heat lamps for bearded dragons come in various shapes and sizes. While investing in a heat lamp, you should check for the size and shape of the heat lamp and whether it will fit the dome or pet enclosure you have set up for your bearded dragon. 

What is the Lifespan of the Heat Lamp?

Since you will have to keep the heat lamp on for approximately 12 hours every day, you might want to look into the lifespan of the heat lamp. It will be tedious for you to change the heat lamp time and again if its life is short. 

Some heat bulbs can last up to as long as 3500 hours. It is wise to invest in a heat lamp that suits all other needs and also has a longer lifespan.   

How Much Does the Heat Lamp Cost?

Finally, you might want to take into account the price of the bulb. Since heat lamps are a necessity and they have to be installed in the pet enclosure at all times, you should take into consideration buying a heat lamp that meets all other requirements and is economical.
