Buying Guide
When choosing a light socket filler, there are a few important factors to consider. Here are some key features to look for:
Compatibility
One of the most important things to consider is compatibility. Make sure the filler you choose is compatible with the light sockets you have. Some fillers are designed to fit specific types of sockets, such as E26 or E27, while others are more universal.
Wattage
Another important factor to consider is wattage. Make sure the filler you choose is rated for the wattage of the bulb you plan to use. Using a filler with a lower wattage rating can be a fire hazard.
Material

Ease of Installation
Finally, consider how easy the filler is to install. Some fillers require tools and can be difficult to install, while others can be installed without tools and are much easier to use.
By considering these factors, you can choose a light socket filler that is safe, durable, and easy to use.
