When setting up a home for your gerbil you may ask yourself, ‘Do gerbils need special lighting in their cage?’ Gerbils are relatively low maintenance pets, but their home environment and behaviors provide clues about their best lighting conditions. Gerbils live in the wild in semi-arid regions with natural light cycling between bright days and dim dusks or dawns.
The lighting needs of your gerbil are important to understand in order to keep your gerbil healthy, comfortable, and happy. Bright light can stress them but complete darkness may interfere with your ability to monitor their active time.
Understanding Gerbils’ Natural Environment
The gerbils are native to Mongolia and Northern China, where they’ve adjusted to cope with ambient lighting and temperature. Bright day light, dim lighting at dawn and dusk are experienced in these arid regions. Gerbils are burrowing creatures, meaning they live much of their time underground in tunnels, away from direct sunlight.
Behavioral Adaptations
Generally, gerbils are crepuscular with their primary time being dawn and dusk. In the wild, this behavior helps them avoid predators while avoiding extreme daytime heat. In addition, they are used to low light conditions as opposed to artificial lighting at high intensity levels, or even total darkness.
Why Natural Light Matters
By trying to match their natural lighting environment, they help keep their biological rhythms right and reduce the stress. If you can’t do that, then placing your gerbil’s cage in a room with indirect sunlight is a great way to imitate those conditions without shocking their sensitive eyes.

Light vs. Dark Preferences
How Gerbils Perceive Light
Gerbils’ vision is adapted for low-light environments. They can navigate in dim settings but may struggle in complete darkness. Bright, direct lighting can overstimulate or even harm their eyes, making a shaded environment essential.
Effects of Light on Behavior
Excessive lighting can disrupt a gerbil’s natural behavior. Bright lights may:
- Increase stress levels.
- Disrupt sleep cycles.
- Cause your gerbil to retreat into burrows or hideouts more often.
On the flip side, dim lighting provides a calming environment. It allows gerbils to explore their cage comfortably and express natural behaviors.
Why Darkness Is Important, but Not Absolute
While gerbils enjoy dimly lit environments, complete darkness isn’t ideal. They need subtle illumination during their active hours to feel secure and navigate their surroundings. Using a soft red or dim LED light can help you observe their nighttime behavior without causing disruption.
Artificial Lighting in Gerbil Cages
Do Gerbils Need Artificial Lighting?
Natural lighting (if provided to your gerbil’s cage in a naturally lit room) doesn’t usually require additional artificial lighting. Gerbils are adapted to the light-dark cycles of the environment, so if it’s of the natural light and then of the light-dark in the night that would be good enough.
Yet, artificial lighting is necessary in some cases, i.e. when their cage is not in a room with a window, or a room lit with insufficient light.
If your office type is artificial, be sure the lights follow natural daylight cycles. Don’t leave lights on for a long time as this will upset your gerbil’s circadian rhythm and impact stress or behavioral changes.
Types of Lights Suitable for Gerbils
When choosing artificial lighting for your gerbil’s cage, opt for gentle and non-intrusive options:
Red Lights: These are ideal for observing your gerbil’s nocturnal activity as they mimic the dim lighting of dawn and dusk without disturbing their sleep.
Dimmable LEDs: These allow you to adjust brightness levels, ensuring a soft glow that won’t overwhelm your pet.
Avoid Heat-Producing Lights: Gerbils are sensitive to heat, so steer clear of incandescent bulbs or other light sources that can raise the temperature in their cage.
Risks of Excessive Lighting
Too much or overly bright lighting can harm your gerbil. Risks include:
Disrupted Sleep Cycles: Bright lights at inappropriate times can confuse their natural activity patterns.
Increased Stress Levels: Continuous exposure to bright light may cause your gerbil to hide excessively or become lethargic.
Potential Eye Strain: Prolonged exposure to harsh light can affect your gerbil’s sensitive eyes, leading to discomfort.
Ideal Lighting Practices for Gerbil Care
Daytime and Nighttime Lighting
Gerbils thrive when their cage mimics a natural light cycle. During the day, indirect sunlight is best. At night, avoid complete darkness by using soft, dim lighting if you need to check on them. For example, placing their cage near a window with sheer curtains ensures a balance of natural
light while preventing direct sunlight exposure.
Creating a Balanced Environment
You can create a well-lit yet comfortable space for your gerbil by:
Gradual Light Transitions: Avoid sudden changes in lighting that could startle them. Using dimmers or timers for artificial lights helps simulate natural light patterns.
Strategic Cage Placement: Keep their cage in a room with consistent, indirect light and away from direct sunlight or artificial light that’s too harsh.
Providing Hideouts: Gerbils love to burrow, and shelters within the cage allow them to escape light when needed.
Special Considerations
Seasonal Adjustments: As natural light shifts with the seasons, consider adjusting artificial lighting to ensure consistency, especially during shorter winter days.
Windowless Rooms: If their cage is in a room with no natural light, a low-wattage bulb set on a timer can replicate a day-night cycle.
Why Proper Lighting Matters
By understanding your gerbil’s lighting preferences and natural behavior, you create a stress-free environment that supports their physical and mental health. Thoughtful lighting choices help maintain their natural circadian rhythm, improve their comfort, and even enhance their bond with you.
FAQs
Do Gerbil Need A Night Light?
One thing you’d be asking yourself is if your gerbils need a night light. If your setup and circumstances aren’t up to your expectations and preferences, the answer will be straightforward.
Gerbils are crepuscular, meaning they are naturally most active during dawn and dusk, meaning in most cases you don’t need a night light for your gerbils.
Yet a dim red light may be good for you as an owner who wants to see their nighttime behavior without disturbing their normal activity. Don’t use bright or white lights at night, as they will get in the way of your circadian rhythm.
Will Bright Light Harm Gerbils?
Bright light can hurt gerbils. Their eyes are very sensitive to light, and if it’s not soft and diffused, generally directly in front of them, they may suffer stress, become uncomfortable, and change their behaviors to excessive hiding.
If your pet’s cage is placed in direct sunlight or under a bright artificial light source, to protect your pet, be sure. Instead of the direct lighting, opt for shaded or indirect lighting.
What is the best Lighting Setup?
The ideal gerbil cage setup, based on what you’ll most likely be doing with the animal, would have some form of light at day and no lighting at night. If natural light isn’t possible, a low wattage bulb or an LED that is dimmable on a timer can mimic a natural day and night cycle.
If you allow your gerbils to run around in the cage, give them shaded areas in the cage where they can get out of light when they may feel like it.
Can a Gerbil Survive without Natural Light?
Though gerbils can adapt to living in artificial light, natural light is preferred for the gerbils’ circadian rhythm and health.
But if your gerbil’s cage is not inside a room with windows, using artificial light programmed with a timer that mimics daylight can also be used to establish a regular rhythm for your gerbil. Be aware not to overuse synthetic light and cause stress or sleep disruption.
Conclusion
Providing the right lighting for your gerbil is a very important part in creating the environment in which your gerbil can feel safe and comfortable. If you can do your best to replicate their natural habitat, dim up when they are awake and don’t blast them with too much light, your gerbil will be thriving. The choice of lighting – whether it be artificial or else – comes down to balance.
Now keep an eye on your gerbil’s behavior, adjust their lighting setup as needed and always focus on the gerbil’s comfort. And with these tips you’ll create a well lit and stress free home for your furry friend and they’ll remain happy and healthy.
