Typically, when you are looking for germicidal light bulbs, you're using a device that has been carefully designed to clean water, air, or other beneficial substance from harmful germs and other pollutants. As we advance more and more in medical knowledge and research, people realize the benefits of making sure the things we put in our bodies really should be as clean as possible. This type of cleaning device is really becoming popular!
The fluorescent style germicidal light bulbs are the most popular right now. You can find them in lots of sizes, but the most popular sizes are G8T5, G15T8, and G30T8. Each of these, along with all the other models can often be found by knowing the length and diameter of your germicidal bulb. You might have to use this method if your bulb doesn't have any printing on it.
Germicidal CFL bulbs are a newer phenomena, but can be preferred by fixture makers depending on the size and use of the fixture. Our compact fluorescent choice are currently offered by Sylvania, GE, and Philips. All of these brands are considered major manufacturers and should be considered as the top-notch options for any type of light bulbs, really.
Because of the way these bulbs will kill bacteria, the most common locations they can be found would be places like hospitals & clinics or in food preparation areas in restaurants. Other places to find them would be swimming pool filtration systems and food processing plants like bottling facilities, dairy processing, and liquid sweetener plants.
