How Often Should You Replace Your UV Light Bulb?

Most lamp manufacturers, such as Phillips, GE, and Sylvania, produce quality lamps that emit at least 80% of their original UV-C emission within a year. However, it is recommended to replace all UV bulbs every three years regardless of how often they are used. This is because the performance of UV lamps deteriorates over time. According to an expert, they should be replaced every 9 to 12 months for maximum effectiveness.

The reason for this is the build-up of scale and solorization, a condition in which quartz discolors and decreases the intensity of UV light. This affects both the material of the lamp and the quartz cover. The effective intensity of UV rays decreases by approximately 40 to 60 percent during 9000 hours (just over a year) of operation. If your UV lamp has reached the three-year mark, it is important to turn off the system until the UV bulb is replaced.

The small seams or openings in the ducts that surround the lamp will allow you to see how the blue light works. It is best to leave the UV water filter system turned on, even when water doesn't pass through it as it requires a very low amount of electricity. The hard glass is pure molten quartz and maintains its ability to transmit UV light for a longer period of time than the soft glass lamp. For example, if the UV lamp is installed in the air conditioning system of a vacation home or other secondary residence where it is not used regularly, you can wait up to two years before replacing the UV bulbs.

UV light purifiers are a great addition to your air conditioning system because they offer many clean air benefits in your home. This means that they gradually lose the intensity of their light waves until they reach approximately 60% of what a new UV bulb provides. The specific lifespan of a UV bulb will depend on the type of system and the manufacturer's recommendations. Research indicates that 99.9% of viruses and bacteria found in air ducts can be destroyed using ultraviolet light technology to improve air quality.

They emit UV-C rays, which represent the wavelength of UV light, which is perfect for killing microorganisms.
