How To Make Black Led Lights

Do you want to see if LEDs can be used to create a blacklight? This tutorial will show you how to create a blacklight using LED light strips. You should be able to make your own black lights utilizing LED strips using locally available resources by the end of this guide.

Before learning how to construct one with an LED light strip, let’s talk about why you’ll need a black light before learning how to construct one. People prefer to use black lights mainly for parties.

Black lights are frequently used to illuminate gloomy parties. There are occasions when neon-colored items, props, decorations, or face paint are desired. You can’t use a regular light for this party type because the items will only glow in the dark. So, the black lights are the main requirement to make any event a little bit dreamier.

Black Lights: An Overview

Black lights use a filter or coating over a bulb to block out the most visible light to produce ultraviolet light. The fluorescent glow created by phosphors that react to light can be seen under a black light.

If you don’t have access to a black light and require one, a flashlight, a smartphone, or a tablet with a built-in flash can simply be used to simulate one. Please be aware that some light sources may become too hot and melt the plastic we’ll utilize in our projects.

UV light, which is beyond the visible light range on the spectrum and more to the violet side, is the main component of black lights. This is why, although feeling its energy as heat, you can’t see it. Black lights, in particular, emit UVA light that is less hazardous.

Phosphors come in a variety of neon colors, including orange, green, and pink. In blacklight, white also glows naturally. You can test your DIY black light with any phosphor you have on hand to see whether it works.

Methods To Make Black LED Lights

You may make a dark light with LEDs in a variety of ways. We’ll look at two standard methods you can utilize from the convenience of your own home.

Use A Remote Controller

If you wish to use this option, you’ll need a high-quality strip light with a remote controller included in the package. We bring this up since all strip lights on the market do not include remote controls.

If you wish to utilize your strip lights as black light, make sure the package includes a remote controller before buying. For this process, the needed supplies are:


  • The light strip must first be installed.
  • Make sure it’s correctly connected to the power source.
  • To change the colour, press the DIY button on the remote.
  • Press the red button a total of 25 times.
  • Now press the blue button for a total of 25 times.

If you already have the LED strips installed, you have to push the remote control. Your LED light strips will begin changing color as you push the buttons on your remote control until you achieve the ideal blacklight effect. While this isn’t quite as good as commercial blacklight, it’s as near as LED light strips will get you.

Use A Transparent Tape

There is a manual technique to manipulate each LED light in the strip to give you similar results if you don’t have a remote or break along the route. To keep UV light, you’ll need this strategy, which involves manually suppressing visible light.

If you don’t have the time, this strategy isn’t for you. It’s most commonly used to convert smartphone LED flashes to blacklights. As a result, we only advocate this strategy if you’re simply using a few LED strips to create a blacklight. The needed supplies for this method are a LED light strip, transparent tape and a blue marker.


  • Count how many separate LEDs there are in the strip.
  • Cut small pieces of transparent tape in groups of three, equal to the number of LEDs.
  • Place the first piece of tape on each LED and use the marker to paint them blue.
  • Layer it all around with the second piece of tape and colour it blue as well.
  • Color the third piece purple and place it on each.
  • Make sure each light is completely covered.
  • Try it out by turning on your white LED light strip.

Instead of using tape, you may use colorful cellophane. To keep the parts in place, though, you’ll need to use clear tape. You don’t have to set the layers in this exact order as long as you have three color layers. You’ll have your own DIY blacklight if you follow the same steps as above.

Using the remote technique is still the most convenient option. When it comes to quality, this DIY blacklight pales in comparison to a legitimate commercial blacklight. Nonetheless, it works well in a pinch and aids in creating UV lighting in a room.

Final Thoughts

To begin, blacklight is a form of UV light. The main difference is that a black light emits very little visible light, whereas UV does not. As you already know how to make a black light with LED light strips, feel free to explore both ways indicated above.

It’s a quick and straightforward solution to use the next time you require a black light. Remember to link or connect the strips with care and care to avoid voltage dips and other electrical difficulties.
