The Huge Difference Between Indoor & Outdoor Light Bulbs | LED PHANTOM


When it comes time to replace your light bulbs, it can be confusing trying to figure out which type you need. Do you buy an indoor light bulb or an outdoor light bulb? What's the difference, anyway? In this blog post, we will discuss the differences between indoor and outdoor light bulbs and how to choose the right one for your needs.

When you read the online description or look at the box for a light bulb, you will see a UL listing. This rating is representative of the bulb’s ability to withstand damp or wet conditions. If the light bulb is only for use indoors, it will have a “D” rating. If it is for outdoor use, it will be labeled as an “OD” light bulb. These ratings are important to take note of because using the wrong type of light bulb in the wrong environment can be dangerous.



Indoor light bulbs are not made to withstand exposure to the elements like outdoor light bulbs are. Outdoor light bulbs need to be able to withstand extreme temperatures, humidity, and even direct contact with water. That’s why they cost a little bit more - they are built to last longer and perform better in difficult

Standard incandescent light bulbs can be used outdoors so long as they are not directly exposed to rain. These bulbs are not as durable as outdoor light bulbs, so they will need to be replaced more often. If you choose to use standard incandescent light bulbs outdoors, we recommend using an outdoor retrofit kit or an outdoor light fixture to protect the bulb from the elements.


Compact fluorescent light bulbs (CFLs) can also be used indoors and outdoors. However, CFLs contain mercury, so if they break, you will need to take special care in cleaning up the area. We recommend using CFLs only in enclosed fixtures where they will not be exposed to the elements.

LED light bulbs are available in all UL rating levels. That means they can be used both indoors and outdoors. LED light bulbs are also more energy-efficient than incandescent or CFL light bulbs, so you’ll save money on your energy bill in the long run.


So, which type of light bulb should you choose? If you need an outdoor light bulb, make sure to choose one that is UL rated for outdoor use. If you need an indoor light bulb, any type of light bulb will do. Just be aware that CFLs contain mercury and should be used with caution. And if you want to save money on your energy bill, we recommend choosing an LED light bulb.
