I’ve always loved experimenting with lighting, and black lights have a special charm. They create a colorful and exciting atmosphere that’s perfect for impressing guests. Plus, with just a few simple supplies, you can easily create your own. LED lights, especially ultraviolet light types, are a popular choice because they’re accessible and energy-efficient.

The process is relatively straightforward. Once you understand the basics—like how ultraviolet light interacts with materials to make them glow—you’ll see why this DIY project is so rewarding. From preparation to building, each step is designed to be easy, even for beginners. So, if you’re looking to add a unique touch to your home decorating or want to explore the capabilities of black lights, this guide will walk you through everything you need to know.

Make UV Light with an LED Flashlight

Here’s what you’ll need:

• LED flashlight or standard flashlight as your base.
• Clear cellophane in purple and blue for filtering light.
• Yellow highlighter to create fluorescein for testing.
• LED strip lights with visible light-blocking paint.
• Power supply and transparent covers for protection.

Step-by-Step Instructions

Step 1: Choose a Light Source

Start with a standard LED flashlight or LED strip as your light source. Ensure the battery is fully charged and the device is functioning by turning it on briefly. If using LED strips, inspect for fraying or exposed wires, clean them thoroughly with an alcohol-based cleaner, and cut to size if needed.

Step 2: Adjust the Frame for LED Strip Lights

Before placing the LED strip, prepare the frame by ensuring it’s clean and free of dirt. Check the area where you’ll apply adhesive to guarantee a smooth and secure fit. A clean surface ensures the strip stays firmly in place.

Step 3: Attach LED’s to the Frame

Using your preferred adhesive, carefully attach the LED strip to the frame. If your strip has double-sided adhesive tape, it makes the job even easier. Ensure the strip is firmly secured for the best results.

Step 4: Position the Frame Under Light and Apply Epoxy

Place the contraption under a bright light to see clearly. Gently apply epoxy on the LED strip surface for a smooth finish. If using cellophane, lay it carefully to avoid air bubbles and ensure even coverage.

Step 5: Apply Blacklight Paint for a Glow Effect

Start by carefully applying blacklight paint in thin, even coats to make the frame absorbent and visible under UV light. Wait for each coat to dry before applying another, ensuring a safer and smoother finish. Follow this process until you’re satisfied with the glow!
