Do Iguanas Need Uvb: How Much Uvb Do Iguanas Need?

As with all reptiles, iguanas require ultraviolet B since it is vital to their health. In this post, I’m not just answering the query are iguanas obligated to have UVB, but also, how much do they require? There are a variety of lighting bulbs available to select from, but not all are appropriate for keeping a pet iguana.

In this article, we review the right bulb type and the proper amount to offer to iguanas to improve their health, well-being and healthy level of activity.

Do Iguanas Need Uvb?

Yes. Iguanas require UVB since it is an essential requirement to make Calcium in their bodies. Without UVB, iguanas may not be able to perform their immune system and risk suffering from serious health issues, such as osteoporosis metabolic.

It is essential to keep the UVB lights in operation all day and turned off only in the evening. Without it, iguanas will be incapable of metabolizing Calcium. The body requires and then metabolizes Vitamin D3. Without Vitamin D3, it will be impossible to process Calcium properly.

In the absence of proper thermal gradients, Iguanas are likely to suffer from numerous health problems. Uvb is part of the Sun’s natural spectrum, allowing reptiles to create and then metabolize Vitamin D3.

If snakes aren’t receiving UVB straight from sunlight, they’ll require UVB bulbs. Not just iguanas but other reptiles need UVB exposure to create Vitamin D3 and process Calcium. An ambient temperature of 95-100 degrees Fahrenheit in their enclosures is essential.

Iguanas also require high humidity in their chambers, around 70%, to avoid kidney diseases and insufficient shed. If temperatures drop to below 40°F, the activity of iguanas will decrease and become inactive.

As they age, the digestion process ceases completely, making Iguanas drop from the tree to the floor in nature or simply lying around inside their enclosures.

Why is UVB crucial for the iguanas?

Yes, it is necessary to allow an iguana’s body to produce vitamin D3. Vitamin D3 assists in breaking down and processing Calcium effectively. Since iguanas are in the Subtropical Woodlands, they prefer to be in warm surroundings.

In many instances, iguanas can be often seen Sunbathing. The Sun’s rays produce three distinct types of light bands, which comprise visible light and infrared and ultraviolet light.

Each of these three types of sunlight is essential for the Iguana’s function in its biological system. Uva, not just UVB, can significantly impact their health. Uva aids iguanas in their daily eating, basking, and breeding. Let’s discuss what happens when iguanas are born with no Uva.

If there’s no UVB light source for your iguanas to absorb light and generate Vitamin D3, they’ll suffer from problems such as osteoporosis metabolism. Without Uvb, iguanas’ day-to-day activities will be severely affected.


The metabolic bone disorder can result in severe muscle and tissue injury. If the tissues and bones are weak, they are more prone to injuries. In the absence of UVB, calcium deficiency is frequently seen in the Iguana. There are a few signs of calcium deficiency

  • Swollen Limbs
  • Fracture/Broken Bones
  • Difficult In Moving
  • Soft/Swollen Jaws
  • Distended Facial Bones

How Much Is Uvb Too Much For A Iguana?

A period of more than sixteen hours of UVB light is thought to be excessive for an iguana’s health. If they are exposed for more than 12 hours, it will not cause a significant impact on their health.

However, turning the lights off during the night is beneficial. Uva is also required for a guana’s health to increase activity level.

How Much Uvb Do Iguanas Need?

Iguana requires 12 hours of UVB lighting to maintain its health. You can switch off the UV bulbs at night and regulate the lighting cycle to suit your preferences.

The most effective way to control the lighting cycle of an iguana would be to set up an automated timer to turn on the UV bulbs. It is recommended to leave the bulbs on for at least 12-13 hours per day in the summer.

The same procedure is required in springtime. When it comes to the colder seasons, you should use UVB lighting for a minimum of 10-12 hours per day during the autumn and winter.

It is crucial to adjust the UVB light of your Iguanas’ set up all year long to control their seasons. It is essential to create a natural atmosphere that iguanas can live in.

How Many Watts Does An Iguana Need?

Under your Iguana’s enclosure size, it will require different wattages for bulbs. Uvb bulbs that are 20 watts are adequate for their health. If your cage is medium-sized, opt for 30-40 Watt bulbs or UVB. For a giant cell that will be the home to an adult Iguana, it is recommended to select a 40-watt bulb.

What UVB Do Iguanas Use?

Based on my research, I suggest you select a 10.0 UVB lamp placed 18 inches higher than the ground. It is crucial to choose the correct fixture to alter its settings to suit the requirements of your Iguana.

Be sure to change the UVB bulbs from time to time, usually every six months. Basking lamps too need to be replaced, and it is essential to determine if iguanas require UVB and UVA.

Do Iguanas Need Uvb Or Uva?

Iguanas require both kinds of light bands to regulate the functions of specific biological systems in their bodies. Iguanas used UVA light to encourage activities such as feeding, breeding and basking. However, iguanas need UVB light to create Vitamin D3 within their body to facilitate calcium absorption.
