Materials Required

If you’re looking to create a black light effect on your phone, you’ll need a few essential materials to get started. Don’t worry, though – these items are easy to find and won’t break the bank. Here’s what you’ll need:

  1. A smartphone: To create a black light effect on your phone, you’ll obviously need a smartphone. Any Android or iOS device will work just fine.
  2. A black light app: There are various black light apps available on app stores. Make sure to choose one that has good ratings and reviews. This app will provide the necessary filters and effects to create the black light effect on your phone.
  3. A dark room: For the black light effect to work effectively, you’ll need to create a dark environment. Find a room in your house where you can eliminate as much external light as possible. This will help enhance the black light effect on your phone.
  4. Optional: A tripod or stand: If you want to keep your hands free while using the black light effect on your phone, consider using a tripod or a stand to prop up your device. This will ensure stability and allow you to experiment with various angles and positions.

Once you have gathered these materials, you’re ready to move on to the next steps and start creating your own black light effect on your phone.

Step 1: Download a Black Light App

The first step in turning your phone into a black light is to download a black light app. These apps utilize the phone’s screen, camera, or flashlight to simulate the ultraviolet (UV) light emitted by traditional black lights. They are available for both iOS and Android devices and can be easily found and downloaded from the respective app stores.

When choosing a black light app, ensure that it has good reviews and ratings, and offers features like adjustable brightness and different color options. This will allow you to customize your black light experience and make it more enjoyable.

After downloading the app, make sure to give it the necessary permissions, such as access to the camera or flashlight, so that it can function properly.

Once you have successfully downloaded and installed the black light app on your phone, you are ready to proceed to the next step and start transforming your device into a black light source.

Step 2: Adjust Screen Brightness

Once you have downloaded a black light app on your phone, the next step is to adjust the screen brightness to achieve the desired effect. The brightness level will determine how well the black light illuminates objects and surfaces.

To adjust the screen brightness on your phone, usually, you can find the option in the settings menu or the quick settings panel. Depending on the operating system of your phone, the exact location may vary.

On most Android devices, you can find the screen brightness settings by swiping down from the top of the screen to open the quick settings panel. Look for the brightness icon or the gear icon labeled “Settings.” Tap on it to access the brightness control slider.

On an iPhone, you can find the screen brightness settings in the Control Center. Swipe up from the bottom (or swipe down from the top-right on newer models with Face ID) to bring up the Control Center. From there, you will see the brightness slider that you can adjust to increase or decrease the screen brightness.

When adjusting the screen brightness for your black light, it’s essential to find the right balance. If the brightness is too low, the black light effect might be dim and hard to see. On the other hand, if the brightness is too high, it might overpower the black light, making it ineffective.

Experiment with different brightness levels until you achieve the desired intensity for your black light. If using the black light app in a dark room, you might need to decrease the brightness compared to when using it in a well-lit area.

Remember, each phone model and operating system may have minor variations in the screen brightness settings. If you’re having trouble finding or adjusting the brightness, consulting your phone’s user manual or searching online for specific instructions can be helpful.

Step 3: Activate the Flashlight

Once you have downloaded a black light app and adjusted the brightness of your screen, it’s time to activate the flashlight on your phone. The flashlight feature illuminates the LED light at the back of your phone, allowing you to create a black light effect. Follow these simple steps to activate the flashlight:

1. Open the black light app you have downloaded on your phone.

2. Look for the flashlight icon within the app. It is usually represented by a small bulb or a lightning bolt symbol.

3. Tap on the flashlight icon to turn it on. Once activated, you will notice the LED light at the back of your phone will brighten up.

4. By pointing the LED light at objects or surfaces, you can create a black light effect. This effect will make certain colors glow or appear fluorescent.

5. To turn off the flashlight, simply tap on the flashlight icon again. The LED light will go off, restoring your phone’s normal functionality.

It’s important to note that the availability and functionality of the flashlight feature may vary depending on your phone’s make and model. Some phones may have a dedicated flashlight button or shortcut, while others may require you to access the flashlight through the settings menu. If you’re unsure how to activate the flashlight on your specific phone, refer to the user manual or search online for instructions specific to your device.

By activating the flashlight on your phone, you can create a mesmerizing black light effect and enjoy a unique visual experience. Whether you’re hosting a party, experimenting with different art projects, or simply want to explore the world in a new light, the flashlight feature on your phone can be a handy tool.

Step 4: Experiment with Different Colors and Effects

Now that you have your black light app installed and your screen brightness adjusted, it’s time to have some fun and explore the various colors and effects that you can create with your mobile phone.

One of the exciting features of black light apps is the ability to customize the color of the light emitted from your phone. You can choose from a wide array of colors, ranging from vibrant neon shades to more subtle hues. Try selecting different colors and see how they affect the objects around you.

As you experiment with different colors, you’ll notice that certain items will react more prominently to the black light. For example, white or fluorescent clothing, certain types of paints, and materials with phosphorescent properties will glow brightly under the black light. This can create a mesmerizing effect and add an extra level of interest to your surroundings.

Aside from colors, many black light apps also offer various effects that you can apply to enhance your experience. These effects can transform your phone screen into a mesmerizing light show. From pulsating patterns and swirling waves to flashing strobes and psychedelic visuals, there are countless options to explore.

Take your time to experiment with different effects and find the ones that captivate you the most. Whether you want a soothing and calming atmosphere or a lively and energetic ambiance, there is an effect to suit every mood and preference.

Don’t forget to involve your friends and family in the fun! Turn off the lights in a room, turn on your black light app, and watch as everyone is amazed by the illuminating effects on their clothes and the environment. It’s a great way to create unforgettable memories and entertain your loved ones.

Remember, the key to truly enjoying the black light experience is to let your creativity soar and have fun with it. There are no limits to the different colors and effects you can try, so feel free to experiment and see what unique creations you can come up with using your mobile phone.


Creating a black light on your phone is a fun and easy way to add a unique touch to your mobile device. With the use of a simple app or by making slight adjustments in your phone’s settings, you can transform your screen into a glowing, vibrant display.

Whether you want to enhance your gaming experience, create a mesmerizing ambiance, or simply impress your friends, having a black light on your phone can be a great way to add some excitement to your day-to-day activities.

Remember to exercise caution when using a black light for extended periods, as prolonged exposure may have adverse effects on your eyes. If you experience any discomfort while using a black light, it is advisable to discontinue usage and consult with a medical professional.
