Heat and light are essential elements in a bearded dragon habitat. However, most beardie owners want to know if a bearded dragon lighting at night is recommended.
So, as a bearded dragon owner, it is essential to know what to, how-to, and when to use the day UVB light on your bearded dragon.

Bearded Dragon Lighting at NightRequirements
Bearded dragons are easy to look after. Apart from monitoring their feeding habits and maintaining a clean environment, these lizard species need good day UVB light.
Ultraviolet-B (UVB) rays from direct sunlight are necessary to provide vitamin D3 to your bearded dragon and help it thermoregulate efficiently.
So, what are the night requirements of UVB light radiation for a bearded dragon?
Most beardies owners want to understand how much night light is sufficient for their pets. Luckily, we have the answer.
But before looking at the lighting requirements, you should understand your lizard’s natural behavior.All lizards are coldblooded creatures or ectothermic.
This means they need to absorb sufficient heat through external heat sources like the sun. [1] So, they require adequate radiant heat as much as they are adapted to low temperatures.
So, can a bearded dragon get too much UVB? Too much UVB light that is producing radiant heat at the same time will be uncomfortable for a bearded dragon.
The three essential night requirements for a bearded dragon include:
12-14 hours of adequate daytime UVA or day UVB light and not at night
Most lighting sources should also function as an additional heat source during the day and not at night (UVB lighting)
It is imperative to turn OFF the lights for another 12 hours at night
Here’s a great video explanation:
Bearded Dragon Origin
Bearded dragons originate from the arid Australian desert. The Arid Australian desert receives an adequate amount of sunlight for approximately 16 hours per day (in the summer months).
This explains why most bearded dragons are inclined towards heat and light naturally. They are adapted to arid conditions.
Therefore, if you have a bearded dragon, you need to replicate the same natural conditions to keep it comfortable and healthy.
This means you should add a sufficient amount of lighting to match the 14-hour long Australian desert conditions.
At night, turn off the light for another 12-14 hours. This particular pattern helps to complete the natural cycle.
So, as an alternative to the sun’s rays, installing the recommended UVB light is necessary.
UVA lighting is also necessary for the bearded dragon tank. This is because your pet lizard will be sitting in its indoor tank for the better part of the day, as opposed to the other wild lizards that roam freely in the deserts.
Understanding the Bearded Dragon’s Day and Night Cycle
Understanding the beardie’s nocturnal behavior helps know if installing lights at night is appropriate. You might be surprised to find that a few species do not mind lighting at night.
Beardies are diurnals. This means bearded dragons will habitually come out during the day to recline or bask lazily and receive sunlight.
Nonetheless, beardies prefer to rest without disturbances or movements whatsoever sluggishly at night.
So, never expose your bearded dragon to UVB lights at night. Except on a few occasions, which we will discuss below.
According to animal research, a bearded dragon’s sleep schedule is at night. [3] These lizards sleep or rest peacefully when it is dark. They are sensitive to light like humans.
Here’s another great video:
What Are the Appropriate Lighting Hours of Nighttime Exposure?
You should know the precise amount of lighting hours recommended for your bearded dragon as the pet owner. [4]
How Short is Too Short?
Most bearded dragons can go a maximum of two days without lighting. However, this is discouraged.
Most reptile species (if not all) are daytime dwellers. They like adequate amounts of natural heat and light. The sun, apart from providing light, produces renewable energy.
The sun’s energy is as essential to a reptile’s body as humans.
So, you should know the exact amount of hours of nighttime exposure for your dragon. Here is a breakdown of the light hours depending on the season.
Spring and Summer
In summer or spring, the sun is mostly out for the better part of the day. So, you do not have to switch on the lighting at night.
Anywhere between 12-14 hours of nighttime exposure is ideal for your bearded dragon.
For instance, you can switch ON the lights from 6 AM to 6 PM or 6 AM to 8 PM during the warmer months.
Fall and Winter
In the winter months or fall season, it is vice versa. The sun is mostly off, and you need to switch on the UVB rays for your Bearded Dragon. [5]
A 14-16 hour cycle is ideal. But again, do not switch the light on at night.
What is the Appropriate Lighting Source?
Note that not all fluorescent lighting sources are appropriate for baby bearded dragons.
The best lighting for a beardie is the full-spectrum UVA light(also called basking area light). [6] This particular light is perfect because of its rays.
The rays do not penetrate the vivarium glass or plastic construction directly. Furthermore, this light does not produce excess heat compared to the other incandescent electric lighting bulbs or ceramic bulbs.
Also, always ensure that the light covers the vivarium tank sufficiently. Add a reflective surface to cover the UV light dome if it does not have one. This reflective surface ensures effective results.
The appropriate lighting should cover at least 2/3 of the bearded dragon tank. But a ¾ tank coverage is enough for baby bearded dragons. Never illuminate the entire enclosure.
Remember: Do not cover the entire beardie’s 40-gallon tank with UVA or UVB light. At least a ¼ uncovered part is enough for the “cooling zone.” [7]

Expert Tips:
If you have to turn on the lighting at night, use a dimmable nighttime bulb or an incandescent bulb. Dimmable infrared bearded dragon bulbs can regulate the amount of light produced for your adult bearded dragon.
Here’s a great video to watch:
If, for instance, your beardie did not get enough natural sunlight during the day, you can adjust the light bulb to its total capacity for about 4 to 6 hours.
Bulb brands produce different watts. [8] Thus, always confirm the watts in a bulb before you pick a bulb for your dragon’s tank.
Similarly, you should know the amount of light that corresponds to the size of the vivarium and the size of your pet beardie. A baby dragon requires 14-16 hours of adequate lighting. [9]
Ordinary fluorescent bulbs can be too weak or strong for your adult bearded pet dragon.
Excess light in the beardie’s tank can result in hormonal release and imbalance.
Exceptional Scenario Where Lighting is Ideal for the Tank at Night
Occasionally, you need to use a spot lamp or provide UVB lighting for your bearded dragon’s tank at night.
At night, the proper temperature [10] to keep the beardie warm should be about 21-24°C (70-75°F). This is according to research.
Here are two instances when providing nighttime lighting or using a UVB lamp is exceptional.
When it is freezing, you should switch on the UVA light. Note that UVA lights not only produce light. These particular bulbs are a substitute for the bearded dragon heat lamps.
They can emit anywhere between 5-7% UV exposure and help maintain the beardie’s body temperature.
When the beardie’s tank isin the basem*nt where night time temperatures at night are below the recommended 31-38°C basking area temperature and 24-29°C daytime temperature.
FAQs
Should I Turn my Bearded Dragons light ON or OFF at night?
You should always turn off your bearded dragons’ light at night.Bearded dragons need total darkness and cooler temperatures to sleep at night.
I Left my Bearded Dragon’s Light ON All Night. What Do I Do?
You should turn it offfor at least 12 hours in the morning. This approach helps to complete the recommended day and night light cycle. [11] Alternatively, install an automatic light timer.
What’s the Appropriate Light Cycle for my Pet Beardie?
The correct lighting cycle is 12-14 hours of UVA lighting in summer and spring and 10-12 hours of UVA lighting in winter and autumn.
How Long Does a Bearded Dragon Usually Sleep?
Bearded dragons usually have 8 to 12 hours of sleep. Additionally, these lizard species sleep at night just like humans.
In Conclusion
So, according to research, bearded dragons do not require heat at night. However, understand adequate lighting hours and how to set up the perfect lighting source for your bearded dragon.

Bearded dragons do not need a source of UVA or UVB at night. As such, you'll want to turn both their heat lamp and UVB off at night. Leaving these bulbs on will make your beardie think it's still daytime and can seriously disrupt their sleeping schedule.
Luckily, your bearded dragon won't suffer any serious health consequences from one night with the lights on. But, the lights will probably disrupt their sleep schedule for a few days. Putting your lights on a timer can help regulate this process and prevent you from making this mistake again in the future.
Turtles, tortoises, bearded dragons, iguanas, and chameleons are some common examples of reptiles that need UVB light. This helps prevent animals from developing hypocalcemia (or lack of calcium). UVB lights should be kept on during the day and turned off at night and should be used along with calcium supplements.
Leaving a light tube on at night in your beardie's habitat is a bad idea. Bearded dragons need a completely dark room to get a good night's rest. Leaving a UV light for beardie on for heat at night will also raise the enclosure's temperature too much, making it difficult for your beardie to sleep.
Your vivarium should mimic the natural heat and light pattern of your bearded dragon's natural environment, and since the temperature in the outback drops after dark, your bearded dragon needs a cooler temperature at night. This means you can turn off your heat lamp at night.
Beardies in the wild receive ultraviolet light and heat from the sun on a daily basis. In order to best mimic the ultraviolet light in an indoor enclosure, high ultraviolet (UVA and UVB) output light bulbs must be used. 1 Fluorescent bulbs and mercury vapor bulbs are the two sources most commonly used in the pet world.
(Outdoors, make sure it's designed to be used outside, and that it's safe from wind and weather.) Out of sight: Try to avoid using the lamp overnight or when you can't monitor it, and make sure there is a working smoke detector nearby.
If your heat bulb is only providing a hot spot for basking and there are under tank heat mats, ceramic heaters, hot rocks or similar providing a general warm background temperature then, yes, it probably can be switched off over night.
During the summer months you should provide your bearded dragon with a minimum of 14 – 16 hours of daytime light and UV exposure and 8 – 10 hours of nighttime exposure. During the winter months the light cycle should be decreased to 10 – 12 hours of daytime light and UV exposure and 12 – 14 hours of nighttime exposure.
My house is cold too, and I lost a beloved herp to hypothermia once. Your beardie will be fine with temperatures as low as 15 Celsius, as long as it's only for a few hours. Alternatively, you can buy a heater that looks much like her lamp, but emits no light.
Place hand warmers or heat packs in a sock and place the sock near your dragon (make sure they don't touch your dragon though, or they could burn her). Keep your dragon wrapped in blankets and use your body heat to keep him warm. If you are able, take your dragon into your car with the heat on high until she warms up.
If your home drops below 15°C (59°F), as mentioned above, then some supplementary overnight heating is required to keep your Bearded dragon warm, although if your home remains above this, then you do not need to provide heating overnight.
Heat pads and panels provide a warm area in the terrarium where reptiles can remain if they need to increase their body temperature. They should be placed on one end of the terrarium, which will allow the far opposite side of the terrarium to remain cooler.
Bearded dragons are diurnal and sleep up to 12 hours daily. People often ask if bearded dragons are nocturnal or diurnal. These reptiles are diurnal, so they are active during the day and sleep at night, similar to humans. If you have a bearded pet dragon, it will be awake during the day and rest when you do.
For the rest of the habitat, I recommend 76 degrees F at the cool end and the hot end should be around 86 degrees F. At night, the temperature, in the cool side, should be in the low to mid-70s.
Though bearded dragons usually sleep lying on their stomachs, there are many other positions some may use. In the wild, some bearded dragons will sleep up in a tree, vertical position.
Lighting is pretty simple; the main two lights you need are the heat lamp and the UVB fluorescent tube fixture. The heat lamp is the easier one to set up; you can buy the reptile heat lamp fixtures at pretty much any pet store. You need a fixture with decent coverage for your tank, a "sun dome" type fixture works well.
How Long Can a Bearded Dragon Go Without a Heat Lamp? Bearded dragons can survive 24 hours without a heat lamp, so long as their habitat remains above 65°F. They need warmth to survive and remain healthy so any longer than 24 hours without a heat lamp poses a significant risk.
Every reptile or amphibian species has different heating requirements and always need a warm-side and a cool-side during the day and at night. This helps them regulate their temperatures appropriately so they can be happy, healthy, and active!
Leaving lights on when you are gone is not only a fire hazard but also increases your electricity bill. Lightbulbs can become very hot and if not used properly can ignite a fire.
Based upon current research, the best suggestion is to use bright, cool tones during daytime hours to increase alertness. During the darker, evening hours, when melatonin production and secretion is vital, switching to dim, warmer tones of lighting may create some benefit for sleep.”
Seeing as a heat lamp bulb's temperature can reach over 480ºF, both of these are a concern. A 24-inch minimum distance is a desirable rule of thumb for bedding, walls, and ceilings.
Bearded dragons need UVB exposure in order to stay healthy, but too much UVB can cause a number of symptoms. These can include eye damage, skin lesions, lethargy, and loss of appetite. If you notice any of these symptoms in your bearded dragon, it is important to reduce the amount of UVB exposure they are receiving.
Like humans, bearded dragons are diurnal: they are awake during the day and they sleep at night. In their natural habitat, they are used to being awake when the sun is up and falling asleep when it is dark outside. For most people, this means that your bearded dragon should be sleeping when you are.
Bearded dragons typically prefer temperatures between 75 and 85 degrees Fahrenheit. Anything below 75 degrees Fahrenheit is considered too cold for bearded dragons and can lead to health issues such as metabolic bone disease and respiratory infections.
However feeding whole pinky mice and not ones that have been cut into pieces can also be a very healthy addition to a bearded dragons diet as they do naturally eat whole prey in the wild.
If your bearded dragon stops eating, don't despair as this doesn't mean they will die. While it mostly depends on the age, health, and weight of your pet, the fully-grown dragon can usually live for three weeks and sometimes up to two months without eating.
You should turn off whatever lights are usually on in their enclosure at nighttime to simulate light changes during the day. Some bearded dragons enjoy sleeping in hammocks, on blankets or rolled up t-shirts, or in their very own bed. Others will use a log, a hide, or a layer of sand to burrow in and feel safe.
A ceramic heater is another alternative. These units screw into a light socket and provide warmth. Once again, make sure you have a protective cover over the enclosure, such as a screen. Under-tank heating pads and heat strips are yet another option to provide heat.
Bearded dragons simply do not need ANY light at night, red or otherwise. Like any other light, this red light will also end up disturbing their sleep. Remember that bearded dragons can see (and sense) extraneous lights, so you would do best to turn them off completely.
Use a heat lamp to create basking areas for the bearded dragon. Basking areas are where the bearded dragon will lay, or perch, during daytime hours in order to receive heat and ultraviolet rays just as it does in the wild. The higher the wattage of the heat lamp, the greater amount of heat it produces.
When a bearded dragon reaches its thermal maximum, it will often sit with its mouth open. This behavior, called gaping, shows that the lizard is at its optimal temperature for basking. This gaping will allow a bearded dragon to dissipate extra body heat.
Let your beardie soak for about 15 – 20 minutes. Once bath time is over, gently pat your pet dry with a soft sowel. This is very important! If he's still damp when you put him back in his tank, the substrate may stick to him.
Like humans, bearded dragons are diurnal: they are awake during the day and they sleep at night. In their natural habitat, they are used to being awake when the sun is up and falling asleep when it is dark outside.
Do I turn off the heat lamp at night? If your heat bulb is only providing a hot spot for basking and there are under tank heat mats, ceramic heaters, hot rocks or similar providing a general warm background temperature then, yes, it probably can be switched off over night.
Bearded dragons simply do not need ANY light at night, red or otherwise. Like any other light, this red light will also end up disturbing their sleep. Remember that bearded dragons can see (and sense) extraneous lights, so you would do best to turn them off completely.
The nighttime temperatures should drop to 72°F (32°C) to 80°F (26°C) within the enclosure. If the temperatures drop below this after turning the heat and light sources off at night, you may need to use a heating device that does not emit light to supplement heat.
If they huddle together under the heat lamp, they are too cold. If they scatter away from the heat lamp and avoid the area directly under it, they are too warm. If they are evenly and randomly spread throughout the brooder, they are just right.
Do Bearded dragons need heat at night? The simple answer to this question is that it depends on how warm your house is. In nature, the temperature drops naturally overnight, and this drop in temperature can be quite dramatic in some areas.
Several studies suggest that light exposure at the wrong time can disrupt circadian rhythm and potentially impact your health. When your circadian rhythm is off, you can end up in a vicious cycle. You can't sleep well at night, and you feel tired and in need of a nap during the day.
