Hey there, fellow gecko enthusiasts! If you’re like me, you probably love caring for your little reptile friends and want to ensure they have the best environment possible.

One common question I hear is, should I turn my leopard gecko’s light off at night? It’s an important question, as lighting is crucial to your gecko’s overall well-being.

In this blog post, we’ll dive deep into the world of leopard geckos, discussing their biology, proper lighting setup, and the pros and cons of turning off their lights at night.

We’ll also explore some alternatives to traditional lighting and ways to ensure your gecko is happy and healthy. So, let’s get started!

Fun Fact #1: Did you know that leopard geckos are one of the few gecko species with eyelids? This unique feature allows them to blink and keep their eyes moist. Check out more about gecko vision at How Good is Gecko Vision?

Understanding Leopard Gecko Biology

To properly care for your leopard gecko, it’s essential to understand where they come from and their natural habitat. Leopard geckos are native to the dry, arid regions of Afghanistan, Iran, Iraq, and Pakistan.

In the wild, they’re accustomed to a specific light cycle that corresponds to their day-night routine.

During the day, leopard geckos typically find shelter in burrows or under rocks to escape the intense heat. They emerge in the evening to hunt for food and explore their environment.

This means they’re primarily nocturnal creatures, which is essential to keep in mind when setting up their lighting.

Their natural light cycle consists of about 12 hours of daylight and 12 hours of darkness. Mimicking this cycle in captivity is crucial to maintaining their health and well-being.

Knowing this, the question remains: Do I leave my heat lamp on all night for my leopard gecko? Let’s explore this further in the next section.

Fun Fact #2: Leopard geckos can see colors! While their vision isn't as sharp as humans, they can still perceive a range of colors in their environment. Learn more about their visual capabilities at Can Leopard Geckos See Color?

Setting Up Your Gecko’s Home

Creating the perfect environment for your leopard gecko means finding the right balance between light, heat, and darkness. The key is to replicate their natural habitat as closely as possible.

Proper enclosure and lighting setup

When setting up your gecko’s enclosure, it’s essential to provide a suitable heat source, like a heat lamp, to keep their environment warm.

Leopard geckos need a temperature gradient in their enclosure, with a warmer basking area around 88-92°F (31-33°C) and a cooler area at about 75°F (24°C).

This temperature range allows them to thermoregulate, which is vital for their health.

A basking light should be on during the day to maintain the proper temperature in the warmer area of the enclosure. However, leopard geckos don’t require bright lighting at night as nocturnal animals.

It’s generally best to turn off the basking light at night to mimic their natural light cycle. So, are night lights bad for leopard geckos? They’re not necessarily bad, but you should consider the specific needs of your gecko.

The role of temperature in their habitat

While turning off the basking light at night is generally recommended, it’s essential to maintain the proper temperature in the enclosure. Nighttime temperatures should stay between 70-75°F (21-24°C).

If your home gets colder than this at night, you may need to use a different heat source to keep your gecko comfortable without disrupting their day-night cycle. We’ll discuss some alternatives in the next section.

Nighttime Lighting: Pros and Cons

Now that we’ve established the importance of mimicking your leopard gecko’s natural light cycle, let’s weigh the pros and cons of turning off their lights at night.

Benefits of turning off the light at night

  • Health and well-being: Turning off the lights at night helps regulate your gecko’s natural day-night rhythm, which is crucial for their overall health.
  • Reduced stress: Constant exposure to bright light can stress your gecko, as they’re naturally more active during the darker hours. Turning off the lights allows them to feel more at ease in their environment.
  • Energy conservation: By turning off the lights at night, you save energy and reduce your electricity bill.

Possible drawbacks and concerns

  • Temperature regulation: If your home’s temperature drops significantly at night, turning off the lights may result in a too-cold enclosure, which can negatively affect your gecko’s health. In such cases, you may need an alternative heat source.

While the benefits of turning off the lights at night generally outweigh the drawbacks, monitoring your gecko’s comfort and adjusting its environment as needed is essential.

Alternatives to Traditional Lighting

If you’ve decided that turning off the lights at night is best for your leopard gecko, you might be wondering about other ways to provide warmth without disturbing their day-night cycle. Here are some options:

Red or infrared lights: friend or foe?

Red or infrared lights have been popular for nocturnal reptiles, as they emit heat without producing bright light.

However, recent studies suggest that leopard geckos can still see red and infrared light, which might interfere with their natural behavior. It’s best to use these lights with caution and monitor your gecko’s behavior for any signs of stress.

Other options for nighttime heating

  • Ceramic heat emitters (CHEs): CHEs produce heat without emitting light, making them an excellent option for maintaining nighttime temperatures. Make sure to use a thermostat to regulate the heat output, and place the CHE outside the enclosure to prevent your gecko from coming into direct contact with it.

  • Under-tank heaters (UTHs): UTHs are heating pads that you place underneath the enclosure. They provide gentle, even heat without producing light. Using a thermostat to prevent overheating and create a proper temperature gradient in the enclosure is crucial.

Remember, the key is finding a solution that works best for your situation and, most importantly, for your leopard gecko. Monitor your gecko’s behavior and adjust its environment as needed to ensure they’re comfortable and stress-free.

Monitoring Your Gecko’s Health and Well-Being

Caring for your leopard gecko means paying close attention to its behavior and comfort. Here are some tips to help you gauge whether your gecko is comfortable with their lighting setup:

Signs your gecko is comfortable with its lighting

  • Activity levels: A happy, healthy leopard gecko will be active during the evening and nighttime hours, exploring their enclosure and hunting for food.
  • Appetite: If your gecko has a healthy appetite and is eating regularly, it’s a good indication that they’re comfortable in their environment.
  • Shedding: Proper shedding is a sign of a healthy gecko. If your gecko is shedding without any issues, their lighting and temperature conditions are likely suitable.

Adjusting their environment as needed

If you notice that your gecko is stressed or exhibiting unusual behavior, it’s crucial to reassess its environment, lighting, and temperature setup.

Adjustments might include tweaking the heat source, trying a different type of light, or modifying the day-night cycle to suit your gecko’s needs better.


Deciding whether to turn off your leopard gecko’s light at night can be a bit confusing, but with the right knowledge and understanding of your gecko’s needs, you can make the best decision for their well-being.

Remember, the key is to replicate their natural habitat and light cycle as closely as possible.

You’ll ensure your leopard gecko thrives in its home by providing a suitable environment, temperature, and lighting setup. Don’t forget to monitor their behavior and adjust their environment as needed to keep them comfortable and stress-free.

Now that you better understand your gecko’s lighting requirements, you can confidently answer the question: should I turn my leopard gecko light off at night?

With the right balance of light and darkness, your gecko will be one happy little reptile!
