Introduction

If you’re new to keeping bearded dragons, you might be wondering why they need UVB lighting and how to set up the proper lighting for their tank. In this post, we’ll cover everything you need to know about UVB lighting for your 40 gallon bearded dragon tank.

What is UVB Lighting and Why is it Important?

UVB lighting is a type of lighting that emits ultraviolet rays in the spectrum that reptiles need to produce vitamin D3. Bearded dragons need vitamin D3 to properly absorb calcium, which is essential for their bone health. Without enough UVB lighting, bearded dragons can develop metabolic bone disease and other health problems.

How Much UVB Lighting Do Bearded Dragons Need?

Bearded dragons need UVB lighting for 10-12 hours per day. The UVB light should cover at least 2/3 of the tank, and be placed about 12 inches away from the basking spot. The basking spot is the area where your bearded dragon will spend most of their time, so it’s important to make sure that’s where the UVB light is focused.

Choosing the Right UVB Lighting for Your 40 Gallon Bearded Dragon Tank

When it comes to UVB lighting, not all bulbs are created equal. There are a few different types of UVB bulbs, including linear fluorescent bulbs and compact fluorescent bulbs. You’ll want to choose a bulb that’s appropriate for your tank size and the distance between the bulb and your bearded dragon.

For a 40 gallon bearded dragon tank, a linear fluorescent bulb that’s 18-24 inches long is usually the best option. You’ll want to choose a bulb with a UVB output of at least 5-6%, but no more than 10%. Anything less won’t provide enough UVB, and anything more can be harmful to your bearded dragon’s eyes.

How to Install UVB Lighting in Your 40 Gallon Bearded Dragon Tank

Installing UVB lighting in your bearded dragon tank is simple. You’ll want to attach the bulb to a fixture that can be mounted inside the tank, or use a fixture that can sit on top of the tank. Make sure the fixture is securely attached so that your bearded dragon can’t knock it over.

If you’re using a linear fluorescent bulb, position it so that it covers at least 2/3 of the tank and is about 12 inches away from the basking spot. If you’re using a compact fluorescent bulb, position it so that it’s on the same side of the tank as the basking spot, and about 6-8 inches away from it.

UVB Lighting Maintenance

UVB bulbs need to be replaced every 6-12 months, even if they still light up. Over time, the amount of UVB they produce decreases, so it’s important to replace them regularly to make sure your bearded dragon is getting enough UVB. You’ll also want to place the bulb where it’s not obscured by anything, like rocks or plants.

Conclusion

Proper UVB lighting is absolutely essential for the health of your bearded dragon. By choosing the right bulb, installing it correctly, and maintaining it regularly, you can help ensure that your bearded dragon lives a long and healthy life.
