How to Darken a Light Bulb for Night Heat for a Pet
- 1). Hold the light bulb's base with your non-dominant hand. Place it on a painting surface such as newspaper spread on a table. Paint the half you can reach, and then allow it to dry.
- 2). Turn over the bulb, and paint the other side. Allow it to finish drying.
- 3). Follow the manufacturer's directions on your glass paint. This will indicate the desired baking temperature and time. The heat will help the paint spread out evenly, giving your bulb a consistent color.
