Did you know that red light therapy has many beneficial effects for humans and animals alike? Read more to find out about how it can be used for bearded dragons!

Bearded dragons are very gentle lizards and are enjoyable pets to have. They’re a great fit for children because they’re docile in nature.

One of the advantages of having a bearded dragon as a pet is that they’re relatively easy to take care of.

They don’t need to eat very often, don’t require much maintenance, and they’ll still be happy even if you neglect them sometimes.

Is Red Light for Bearded Dragon Good or Bad For Them?

Though our pet store owners might tell us what we need, their expectations for lizards might not match up with the reality of what types of supplies are necessary.

For example, one expectation among them might be that you will keep your creature warm and healthy.

Let’s explore the advantages and disadvantages of beardies with red lights below.

How Does A Bearded Dragon React To The Red Light?

If you’re considering getting a bearded dragon, many say a red light to help it sleep at night.

Regardless of the color of the light, bearded dragons do not require any kind of lighting.

Although it is considered a non-disturbing light for the animal, they are able to see the red color quite well, so it becomes a very disturbing light for them.

Can Red Lights Hurt A Bearded Dragon?

You can’t use a red light for a bearded dragon because they’re not compatible with the animal’s needs.

Additionally, bearded dragons are lizards and they have incredible vision of the red spectrum. That means a red light bulb is not ideal for basking or nighttime heating.

Though bearded dragons do not need nighttime lighting, they do need daylight. The light will be useful for them when they are outside in the mornings and evenings.

Is Using Red Light Safe For Bearded Dragons?

Try NOT to use red light for bearded dragons. This is a general rule to make sure no kind of red light is in the tank or anywhere near it.

When exposed to the red light, it can cause stress and cause sleep deprivation, loss of appetite, and other health problems.

Amateur pet owners might mistakenly purchase a red bulb for their lizards. They’re often labeled as red basking lights, which makes it easy to get what you need.

The bearded dragons were believed to be able to see the infrared light as one of their colors in the visible spectrum, which would explain why they react that way.

However, it turns out that for them red has nothing to do with heat sensing. If you want to find out the harm that spins could inflict on your content, just keep reading.


Insomnia is a state of inability to sleep.

There is plenty of evidence showing that the red light that amateur-owners get for their young beardies is visible to the lizards at night.

The available facts about lizards don’t back up this claim. They can see red on the color spectrum, and their sleep schedule is never disturbed throughout the night.

It disrupt the appetite of the animal by causing stress and this is not helping them in any way, shape, or form.

Damages the eye:

A bearded dragon’s eyes are particularly sensitive to the UV rays of direct sunlight.

Their eyes must be protected from being exposed to direct sunlight, and this means they need bright lights at all times, especially to make their pupils contract.

Red lights, despite not being as bright, still will damage the eyes due to the UV rays in the lights. These damages are long-term and could result in lasting effects on a person’s eye health.

Disruptive Immune system:

Bearded dragons are prone to many problems caused by red light, which can be easily solved through a good night’s sleep. There are some who believe that the red lights help to maintain the body temperature of the lizard.

Red light does not provide enough heat and it disrupts the creature’s sleep, which can then lead to an immune system disruption.

Do Bearded Dragons Really Need A Red Light At Night?

It’s common for people to make mistakes when they’re buying new lizards. For example, most new lizard owners will buy all the accessories in bulk without taking into consideration the requirements of their new pet. 

However, for bearded dragons, the lights that color are detrimental. In addition to keeping the dragons warm at night, the red light is said to keep them warm in the daytime.

Bearded dragons are capable of maintaining a comfortable body temperature on their own, so long as the ambient temperature where they live is warm.

For younger bearded dragons, an ideal temperature at night should be 20° Celsius or 68° Fahrenheit.

How Warm Should A Bearded Dragon’s Cage Be?

Bearded dragons can see the color red with ease. As a result, they should never sleep near a red light – as this will make them stressed or woken up constantly by the intense light.

You may have heard that light bulbs can be harmful to pets. However, because it’s necessary to have a way of warming them up, this could be inconvenient.

For bearded dragons, the ideal temperature is between 20-22 degrees Celsius. To make measuring the temperature easier, we will list our suggestion for thermometer use below.

At day:

The creature only needs a temperature of approximately 75-85°F or 24-29°C during the daytime. Usually, this is about the same temperature as your average household’s ambient temperature.

To produce a warm glow in their bodies, we do not need to install colored light bulbs.

At night:

The bearded dragon needs a basking spot of at least 68 degrees Fahrenheit or 20 degrees Celsius during the daytime.

The best temperature is between 70-75 degrees Fahrenheit or 21-24 degrees Celsius.

Like I’ve mentioned before, these winter temperatures are normal in these parts. As a result, the idea of having any kind of light to keep oneself warm at night becomes irrelevant.

What Color Light Do I Utilize For My Bearded Dragon At Night?

If we get a bearded dragon and the accessories for it, we might end up with red lights for its cage.

And we’re well aware of how all those forms of light aren’t good for the health of bearded dragons, so it’s better to skip them. Instead, you should use a different form of light or an alternative to red lights for the sake of your bearded dragon’s health.

Here is a list of alternatives to red lights for bearded dragons in the evening.

  • Ceramic Bulbs: Bulbs made of ceramic
  • Fluorescent Bulbs: Bulbs that emit fluorescent light
  • Mercury Vapor Bulbs: Bulbs that emit UVB

Keeping A Bearded Dragon Warm At Night?

bearded dragons don’t need anything specific at night to stay warm. As a result, if the temperature in our area goes down 68°F or 20°C then a way to keep the beaterd dragon warm at night becomes necessary.

Keeping your bearded dragons warm in the winter can be a challenge. Here are some tools you will need to get them through the cold nights.

Ceramic Bulbs:

There’s a cheaper alternative to the ceramic bulb that we’ve featured in comparison. It doesn’t work as well during the day, but it’s perfect for keeping your lizard warm at night.

While UV rays are beneficial for humans, it’s best not to use regular light bulbs if you want these rays. You should only use fluorescent light bulbs or heat lamps for this purpose.

Mercury Vapor Bulbs:

Though these lights cost more upfront than the other bulbs on this list, they last longer and need to be changed less frequently.

Although these bulbs emit UVB, they also provide heat. This makes them the second-best choice for your terrarium because it won’t be too cold for your lizard at night.

Ceramic Heaters:

Of all the solutions we have discussed so far, this is the most expensive and it’s perfect for our little friend who has trouble sleeping at night.

Ensuring your bearded dragon gets undisturbed sleep, as well as appropriate warm temperatures, is important for its overall health. A ceramic heater does both of these things.

Although they can heat a rather narrow area, they still need to be compatible with different sizes of cages or tanks. We would like this size to accommodate as many animals as possible.

In Conclusion

The fact is, as many people know who keep them as pets, lizards can see the red color on the spectrum. That means that bearded dragons will be able to see it too. Keeping them under a red light all night is bad and can harm them.
