How to paint a light bulb with acrylic paint

If a bulb is intended only for decoration and will never be energized, paint it after cleaning; working bulbs should not be coated unless the manufacturer explicitly permits it.

Step 2: take any kind of tape and cover all bulb metal surfaces. Tape protects the bulb metal from paint. But if you want to paint metal, you can do it. It is not harmful to your bulb.

Heat, smooth glass, and repeated thermal cycling can cause ordinary acrylic to discolor, soften, or peel, which is another reason not to coat working bulbs casually.

For an energized bulb, use only a coating specifically approved by the bulb manufacturer for that bulb type and operating temperature; otherwise leave the glass unpainted.

Glass paint: This paint is recommended to paint glass-related surfaces. This type of paint adheres very well on a glass and long-lasting life. And not peel off from the surface. For glass paint, choose heat-resistant glass paint.

Enamels paint: This is a good type of paint for painting glass. This paint is also the least long on bulb glass. Take one coat on glass, it will survive easily.

Engine paint: You also can use car engine paint on the bulb. It can survive on bulb heat. This paint sticks like glue. You can paint multiple coats to make your painting brighter.
