How long do germicidal bulbs last?
5,000 to 9,000 hours
The germicidal UV-C lamps have a useful average life of 5,000 to 9,000 hours. Useful life means that during this time the lamp is operating at an optimal output level for neutralizing mold, fungus, bacteria and viruses. Inherently, fluorescent technologies like UV germicidal lights depreciate in output over time.
At what wavelength is UV light germicidal?
260 to 265 nm
The most effective germicidal wavelength occurs at a peak of 260 to 265 nm at which DNA absorbs UV the most (5, 6), and LEDs can be designed to produce these specific wavelengths.
Does Philips UV-C lamp produce ozone?
This means that Philips TUV lamps do not produce ozone. There is a protective coating on the inside of the Philips TUV glass. This ensures that the UV-C radiation from a Philips TUV lamp barely decreases throughout the long lifetime.
How do a germicidal bulbs work?
In germicidal applications, they function by creating ultraviolet light in a specific range as a mutagen that is effective at killing bacteria by disrupting its DNA structure. High pressure lamps work the same way, but generally create a higher intensity output in a wider range of UV light.
How often should I change the bulbs in my UV lamp?
How often do I need to change my UV lamp? UV lamps should be replaced once every 12 months. UV lamps have a lifespan of approximately 9,000 hours. Calculated out, this means the lamp can operate for about 375 days before requiring a replacement.
How often should you use a UV light?
approximately every 12 months
The frequency of changing a UV lamp for effective indoor air quality improvement depends on how you are using the system. Typically, a UV lamp being used primarily to disinfect the air circulating through a home or small office should be replaced every 9000 hours or approximately every 12 months.
Which nm wavelength of ultraviolet light is used for sterilization?
For UV sterilization, only UVC (100-280nm) has high enough energy to effectively kill microorganisms. When you are shopping for a UV sterilization product to try in your home or business, make sure that its UV wavelength falls in the range of UVC (100-280 nm).
What is the smell after using UV light?
However, with the use of these devices it has been often noticed that there is a residual odor after disinfection, otherwise known as volatile organic compounds (VOCs). This odor has been described as a sulfuric smell similar to rotten eggs, garlic, or burning hair.
Which is better ozone or UV?
The short answer: Ozone is a more powerful oxidizer in swimming pool water than ultraviolet (UV-C). In fact, UV is not an oxidizer at all! We’ll also talk about how they work together to make the most powerful pool sanitizer on the market.
Can I put a UV light bulb in a regular lamp?
However, not every ballast can run every ultraviolet bulb. The more specialized the UV bulb, the more particular it is, and the more difficult it can be to find a compatible ballast. For a regular G4T5 lamp, many ballasts that run F4T5 bulbs will work.
