What Light Does A Chameleon Need

Chameleons, the colorful reptiles native to warm climates, are known for their remarkable ability to change color. But what kind of light do these animals need to maintain a healthy lifestyle? In this article, we’ll explore how different types of lighting can affect chameleon health and wellbeing.

We’ll also discuss how much light your pet chameleon should be exposed to each day and why it is important that they receive the correct amount. Finally, we will look at some popular lighting options available for keeping chameleons in captivity. So if you’re wondering what light does a chameleon need, read on!

Chameleons are known to be sensitive to light and require a specific amount of UVB rays in order to stay healthy. Too much or too little light can lead to health issues, so it is important that you provide your pet chameleon with the right type and amount of lighting.

UVB Lighting

The most important type of lighting for chameleons is UVB lighting, which provides the ultraviolet B (UVB) rays necessary for vitamin D3 synthesis. Vitamin D3 helps your chameleon absorb calcium from their food, keeps them healthy, and prevents metabolic bone diseases like MBD. A lack of UVB exposure can also cause eye problems such as cloudiness or blindness.

There are two types of UVB bulbs available for chameleon cages: compact fluorescent bulbs (CFLs) and mercury vapor lamps (MVBs). CFLs emit moderate amounts of UVB over short distances; however, they need to be replaced often because their intensity decreases quickly with age. MVBs give off more intense levels of UVB radiation but have shorter lifespans than CFLs due to the mercury content.

Lighting Strength & Duration

It is recommended that adult chameleons receive 10-12 hours of daily sunlight or artificial light per day, while juveniles should get 14-16 hours per day. The strength should range between 5% – 10% depending on species and location within the cage; basking areas should get the higher end of this spectrum while cooler areas should have lower intensity lights. Lights should be positioned 6” – 12” away from the basking surfaces for optimal results and turned off at night for 8-10 hours of darkness each day.

Other Considerations

In addition to providing proper lighting conditions, there are other factors that must be taken into consideration when caring for a pet chameleon:

  • Temperature: Chameleons thrive in temperatures ranging from 70°F – 80°F degrees during the day.
  • Humidity: Humidity levels should remain above 40%, ideally around 60%.
  • Plants & Branches: Live plants will help create an environment that mimics their natural habitat.

Do Chameleons Need Uv Light At Night?

No, chameleons do not need UV light at night. In fact, it is important that chameleons have periods of darkness during the day and night to help them rest and recuperate. When a chameleon does not receive enough sleep at night, its health can suffer significantly.

UV light is beneficial for reptiles as it helps them absorb calcium from their diet and also helps regulate their body temperatures during daylight hours. However, too much exposure to UV light can be harmful for chameleons as they are very sensitive to ultraviolet radiation.

During nighttime hours, when UV light is absent and darkness prevails, there should be no artificial lights used in the enclosure so that the animal can get proper restful sleep. Chameleons require 10-12 hours of uninterrupted darkness each night in order to remain healthy and thrive in captivity.

How Much Light Does A Chameleon Need?

Chameleons require between 10 and 14 hours of light per day in order to remain healthy. This can be provided through natural sunlight or by using a full-spectrum reptile bulb, which emits both UVB and UVA radiation. In the wild, chameleons will bask in the sun for long periods of time during the mid-morning and late afternoon when temperatures are at their highest.

In captivity, providing your chameleon with an appropriate amount of light is important as it plays a role in thermoregulation and helps regulate hormones that control growth and reproduction. Additionally, since most species of chameleon originate from areas with high levels of UVB radiation, they need exposure to these wavelengths in order to synthesize vitamin D3 which is essential for calcium absorption.

Without access to adequate amounts of UVB radiation, your pet could develop metabolic bone disease (MBD), a common health issue among captive reptiles caused by a lack of vitamin D3 synthesis due to inadequate lighting setups.

Does My Chameleon Need A Heat Lamp?

Yes, a heat lamp is an important part of providing the right environment for your chameleon. A chameleon needs both UVA and UVB lighting to stay healthy, as well as a basking spot that provides proper warmth.

The combination of these two elements creates the correct temperature gradient in the enclosure that allows your pet to thermoregulate. Without this light source, it will be difficult for your chameleon to obtain enough energy from its food sources and may even lead to health problems such as metabolic bone disease.

Heat lamps are available in a variety of sizes and wattages depending on the size of your enclosure and how many reptiles you plan on keeping inside it. When selecting a heat lamp, make sure it emits an appropriate amount of infrared radiation (measured in microwatts per square centimeter) so that your pet can maintain its body temperature without becoming too hot or cold. Additionally, make sure to place the lamp at least 18 inches away from any openings so that there is no risk of burns or other injury due to direct contact with the bulb.

What Level Of Uvb Does A Chameleon Need?

Chameleons need a moderate to high level of UVB radiation in order to stay healthy and thrive. This is because they need ultraviolet light for the production of vitamin D3, which is necessary for calcium absorption and metabolism. Without enough Vitamin D3, chameleons can develop metabolic bone disease, which can be fatal if not treated properly.

The exact amount of UVB that a chameleon needs will depend on the species; however, most experts recommend having between 10-12% of UVB lighting in the enclosure. This should provide enough light for them to produce adequate levels of Vitamin D3 while still maintaining their natural behaviors like basking in the sun.

If you are using artificial lighting as your only source of UVB then it is important to regularly check and replace bulbs according to manufacturer’s instructions as they degrade over time and may no longer emit enough light even when new.

Additionally, make sure that there are no obstructions blocking the light from reaching its target (i.e., your pet). Finally, providing an area with some shade or indirect sunlight can help regulate your chameleon’s exposure and prevent any potential health complications from overexposure to UVB rays.

Should I Turn The Heat Lamp Off At Night For My Chameleon?

Yes, you should turn the heat lamp off at night for your chameleon. Chameleons are crepuscular animals, which means that they are most active during dusk and dawn. During the night, they will typically go into a state of torpor or brumation in order to conserve energy. This is a natural process that helps them to survive through periods when food is scarce. If you leave the heat lamp on while they’re trying to rest, it will disrupt their sleep cycles and cause stress.

It’s also important to remember that chameleons need temperatures that vary throughout the day in order to stay healthy. They require warm basking spots during the day so that they can digest their food properly and then cooler temperatures at night so they can get a good amount of restful sleep.

Keeping the heat lamp on all night would make it too hot for them, leading to overheating and possible health problems down the line. It’s best to turn it off when your chameleon has gone into its nighttime resting period so as not to interfere with this natural circadian rhythm.


In conclusion, light is essential for chameleons to stay healthy and live a full life. The type of lighting and amount of UV provided should be carefully considered when setting up an enclosure for these reptiles. A combination of natural sunlight supplemented with appropriate artificial lighting can ensure that your pet receives the right amount of light.

Additionally, it’s important to monitor exposure levels and adjust accordingly to ensure they are not getting too much or too little light throughout the day. With proper care and attention, you can provide your chameleon with the best possible environment in which to thrive.
