How to Put Led Lights in Epoxy Resin

One of the benefits of using led lights in epoxy resin is that it creates a unique and eye-catching effect. Adding light to an epoxy resin project can also benefit visibility, safety, and decorative purposes. Additionally, LED lighting is energy efficient and long-lasting, meaning your project will look great for years. In this blog post, You will learn how to put led lights in epoxy resin.

Step-by-Step Processes for How to Put Led Lights in Epoxy Resin

Step 1: Inspect the LED Lights

Before you start, ensure the LED lights are in good working condition. Check for any broken or corroded components and replace them if necessary. Mix the resin according to the manufacturer’s instructions. Ensure it is properly mixed before pouring it into a mold or container.

Step 2: Place LED Lights in the Resin

Once you have your resin prepared, carefully insert the LED lights into the mixture. Make sure they are properly submerged and spaced out evenly. Once the lights are in place, pour more resin over them to cover them completely. Make sure there is enough resin to fill up the mold or container.

Step 3: Remove any Air Bubbles

Using a craft stick or stirrer, gently move the resin around to remove any air bubbles that may have formed. Now it’s time for the resin mixture to cure and harden. Depending on the type of resin used, this can take anywhere from a few hours to several days.

Step 4: Remove the Mould or Container

Once the resin has cured, remove it from the mold or container. Take care not to damage any of the LED lights in the process. Clean up and sand down any rough edges around the resin piece with fine-grit sandpaper. This will help give it a more professional and polished look.

Step 5: Test the LED Lights

Before you use your new resin piece, turn on the lights to ensure they are working properly. Now that your LED lights are safely set in resin, you can enjoy their brilliant illumination. In addition to the steps outlined above, it’s important to be mindful of safety precautions when working with epoxy resin and LED lights.

When handling these materials, wear proper protective gear, such as gloves and goggles. Additionally, ensure that your work area is well-ventilated to prevent fumes or odors from accumulating.

Safety Precautions for How to Put Led Lights in Epoxy Resin

  1. Wear protective gear such as gloves and safety glasses when handling resin, LED lights, and other materials involved in the project.
  2. Read and follow instructions for each resin product for proper mixing ratios and curing times; failing to do so may result in a weakened or ineffective bond between the resin and embedded items.
  3. Work in a well-ventilated area to prevent exposure to fumes and odors caused by the resin.
  4. Avoid spilling or splashing resin on your skin, as it may irritate.
  5. Test an LED light before embedding it in resin, ensuring the connection is secure and the lights turn on properly.
  6. Place LED lights in the resin before it hardens, ensuring they are secure and firmly embedded.
  7. Dispose of unused epoxy resin properly to avoid potential hazards due to incorrect storage, exposure, or contact with other materials.

By following these safety precautions for putting LED lights in Epoxy Resin, you can ensure that your project will be successful and safe. Additionally, it is important to do research ahead of time to find the right materials and tools for putting LED lights in epoxy resin.

What Kind of Power Source Should You Use for Your Led Lights?

When powering your LED lights in an epoxy resin project, you have two main options: battery power and a USB connection. Battery powered LEDs are suitable for projects that do not require a lot of light or will be used infrequently. A USB connection is recommended if you need more light output or want to use the lights frequently.

Battery Powered LEDs Are Suitable

When choosing the type of battery for powering your LEDs, you’ll want to select one rated for at least 3 volts and has an amperage output of at least 500 mAh. A higher voltage battery will help ensure that your LED lights stay lit for longer. However, be sure not to use batteries with an amperage output that is higher than what your LED lights require, as this could cause damage or overheating.

How Do You Make Sure That Your Project is Fireproof and Safe?

When working with any kind of electronics, it is important to ensure your project is fireproof and safe. This means ensuring the power source you use is rated for the electricity needed to operate the LED lights in resin. It also involves ensuring that all electrical connections are properly insulated and grounded. 

Finally, you should take other steps to protect your project, such as not using too much resin or working in a well-ventilated area. You should also be careful to avoid direct contact with the LED lights while they are on, as this could cause serious harm. Taking these precautions will ensure you create a beautiful, safe, and enjoyable piece for years.

What Kind of Maintenance Should You Take Into Account While Working With Epoxy Resin and Leads?

When working with epoxy resin and led lights, it is important to consider the proper maintenance of the epoxy resin. This includes ensuring no air bubbles or any other imperfections in the mix when adding the LED lights. Additionally, it is important to monitor the temperature and humidity levels while you are working, as these can affect the curing process of the resin.

Monitor the Temperature and Humidity

Furthermore, it is important to keep the epoxy resin mixture dry when adding LED lights, as this could weaken structure. After you have finished working with your LED lights and epoxy resin, store it away from direct sunlight and extreme temperatures. This will help ensure that the resin and lights remain in good condition for longer.

Additionally, keeping an eye on the LED’s battery life and replacing them when necessary is important. This will prevent any damage to the epoxy resin and LED lights from occurring due to a weak or dead battery.

How Can You Avoid Getting Air Bubbles in Your Epoxy Resin?

When using epoxy resin with LED lights, it is important to avoid getting air bubbles in the mixture. This can hamper the light from shining through and cause your project to look unfinished. Here are some tips on how to avoid air bubbles when putting LEDs in epoxy resin:

  1. Ensure all your materials, including the Flux, LEDs, and epoxy resin mixture, are at room temperature before beginning.
  2. Work in a well-ventilated area, as this will help reduce the chances of getting air bubbles in the mixture.
  3. If possible, use a vacuum chamber to remove pre-existing air bubbles from the epoxy resin mixture before adding the LEDs.
  4. Stir the mixture slowly and continuously until all ingredients are well combined.
  5. Pour the epoxy resin mixture into your mold or container as quickly as possible to ensure that any air bubbles will be released during this process rather than later when the LEDs are inserted.
  6. Once poured, gently shake or tap the bottom of the container to help remove any air bubbles that may have been trapped in the mixture.
  7. Insert your LEDs into the epoxy resin before it hardens completely, ensuring they are securely held.
  8. Apply a few drops of flux around each LED and use a heat gun to help expel any remaining air bubbles from the mixture.
  9. Allow your project to cure at room temperature before using the LED lights.
Use a Heat Gun to Help Expel

By following these steps, you can ensure that your project looks professional and vibrant with the help of LEDs in epoxy resin.


There are a few disadvantages to consider when using led lights in epoxy resin. Firstly, the light’s heat can cause the epoxy to degrade over time. Secondly, depending on where and how you place your LED lights in the epoxy, it can be difficult or impossible to remove them if needed.

In conclusion, if you want to add LED lights to your epoxy resin projects, it’s important to know how to do it properly. First, ensure the power source is powerful enough for the LEDs. Then, use heat-resistant electrical tape or silicone wire and seal all connections.

Finally, use a drill bit designed for plastic to create holes and insert the LEDs. This article has been beneficial for learning how to put led lights in epoxy resin. Make Sure the preventive measures are followed chronologically.
