Painting a light bulb blue is an easy way to add some pop to your room. It can be done in less than ten minutes and will only use one drop of paint!


This blog post will give you tips on painting a light bulb blue and provide pictures for easy understanding.

This easy project can be done in your home and doesn’t require any special skills or tools. The only required materials are water-based paint, a brush, and a glass jar to mix the paint in. So let’s get started!

  1. Light Bulb
  2. Acrylic paints of different colors
  3. Paint Stirrer for Acrylic Paints
  4. Water
  5. Glossy or Matte Spray Paint

7 Steps to Follow: How to Paint a Light Bulb Blue

Step 1: Prepare Your Work Area

Lay down some plastic wrap to protect surfaces and closets from excess paint. Also, put on protective gloves and eyewear.

Step 2: Remove the Light Bulb from the Socket

Unscrew the light bulb, and place it in a place where nothing can break or touch it. It’s important to make sure that no foreign objects interrupt the drying process of your paint job, so keep it safe!

Although you will need to be careful when removing the light bulb from its socket, make sure to avoid touching any glass with your hands. The oils on your fingers will cause the paint to not properly adhesive.

Step 3: Clean the Bulb

If your light bulb is a little dirty, don’t fear! First, wipe it down with a clean cloth until the glass is spotless. If you’re using a new light bulb, make sure to keep the protective cover on it for now.


Step 4: Prime Your Light Bulb

Use a primer before painting your light bulb to give the paint a clean surface to adhere to. Make sure the primer is dry before moving on!

Step 5: Paint Your Bulb Blue

You’ll need to use at least two coats of blue paint. Let the bulb dry between each coat for increased adhesion and even coloration.

Step 6: Add a Sealer Coat

Use a sealer before you hang your painted light bulb back up in its socket! This will prevent any damage from occurring and ensure that a single bump doesn’t ruin your hard work.

Step 7: Reattach the Bulb to Its Socket

Make sure your painted light bulb is in a safe place while it dries and preferably out of the way so that no one bumps into it accidentally!


Then, gently screw it back in when you think it’s dry enough. Of course, you can always keep the protective cover off to make sure it’s dry if you’d like.

Tips and Tricks:

1. Start with a clean, adequately lit work area. (Ideally, this would be outside or in a place where you’re not worried about small paint spills and drips.)

2. Make sure the light bulb is cool to the touch. You should test it by touching it first; if too hot for your fingers, let it sit for a while until it’s cool.

3. Take off any stickers or labels on the glass part of the bulb; they will be tough to paint over later if you don’t.

4. Put on latex or other disposable gloves to keep the oil from your skin off of the glass. You can also do this after you’re done and don’t want to paint fingerprints anymore.

5. Remove any screws and carefully take apart the metal pieces of your light bulb; lay them out flat so that they won’t get paint on them.

6. If there are any wires or small metal attachments, you can either remove them completely or lay down some thick masking tape to cover the ends of them, so they don’t poke through your fabric later.

What Type of Paint Should You Use for a Light Bulb?

You should use paint that can handle the high temperature of a lightbulb. This means it must be low-odor, low-VOC (volatile organic compounds), and any paint containing chemicals like ammonium hydroxide.


You can use regular acrylic paint or any kind of spray paint – you don’t need to buy speciality paints.

I used about half an inch in diameter of matte blue craft paint with a glossy finish (the same one they used for my New Year’s Eve Ball).

It was good quality but very thin and required several coats to look blue for the bulb.

Some Advantages of Painting a Light Bulb Blue

1. It Makes the room look cooler in summer because the heat from the lightbulb is trapped inside and turns into infrared light, heating your body instead of just making light for you to see by. (note that it doesn’t make much difference, the lightbulb will emit more infrared light)

2. Creates an illusion of a larger space. As lightbulbs are often the only source of light in an otherwise dark room, it makes the space look much larger.


3. If you want to make a room look like a highly pure light source lights it (and not by four 5 Watt bulbs), painting the bulb blue certainly helps.

4. Painting a lightbulb blue can be cheap. All you need is an empty spray bottle and some blue paint, both of which should be available at your local hardware store.

5. A lightbulb painted blue can be used as a night light for kids afraid of the dark. The blue light makes the room look more friendly.


You’ve probably seen a lot of different light bulbs in your day. There are incandescent, fluorescent, LED, and even halogen types that can be found at the store.

But what you may not know is how to paint a light bulb blue! That’s why we’re here today to show you how it’s done; it’s quite easy! 

You first need to find an empty paint bottle with liquid inside (we used blue). Then unscrew the bulb from where it sits on the ceiling or wall socket and pour some liquid into said hole.

Next, screw back onto the lamp base/socket and wait for about twenty minutes before switching on again! Your new blue light will now illuminate any room with a very soothing glow.
