    I used the light in my hvac system. It's a replacement bulb. There are 2 of these attached to the system I'm using. Seem to be working fine, we'll see how long they last.
Everyone is familiar with germs and what they are capable of doing to our immune systems. Germicidal UVC light bulbs are a perfect solution to this problem as they can not only kill germs but prevent them from multiplying in the future. This technology is revolutionary and constantly being improved to work against more and more bacteria.

We offer many options so you can be sure of finding what you are looking for!

What Are UVC Germicidal Lights?

There are three types of UV radiation (UVA, UVB, UVC) and they are classified according to their wavelength. The two ways they differ is in their biological activity and the extent to which they can penetrate the skin. The shorter the wavelength, the more harmful the UV radiation but it also makes it less able to penetrate the skin.

A germicidal light bulb is a special type of light that produces short-wave ultraviolet (UVC) light. Their wavelength is between 100 to 280 nanometers (nm). UVC light deactivates the DNA of bacteria, virus and other pathogens and thus ends their ability to multiply and cause disease. Specifically, the light causes damage to the nucleic acid of microorganisms by creating bonds between certain bases in the DNA. The formation of such bonds prevents the DNA from being unzipped for replication, and the organism is unable to multiply. In fact, when the organism tries to replicate it will die, effectively ending any further bacteria growth.

Differences Between UV Lights and Black Lights

A confusing point for many UV light bulb shoppers is trying to find the difference between black lights and UV lights. To put it simply there isn’t a difference, just a misunderstanding of each term. Black lights are a kind of UV light because they emit ultraviolet radiation. They are classified as UVA (long wave ultraviolet A) light which is the longest UV wavelength on the market right now.

Are UVC Lights Safe?

Unlike some other hazards, exposure to ultraviolet light doesn’t produce a natural avoidance response (i.e. squinting eyes in bright sunlight) or a physical trigger that protection is necessary (i.e. heat radiating from a hot pan). The physiological effects of UVC exposure are also delayed and can appear up to six hours later. It is important to remember that, though the effects may not be felt immediately, to still treat UVC light bulbs with the same caution that you would any other light bulb.

Can You See UVC Light?

Ultraviolet light is defined as “beyond violet light” and the visible spectrum is one that cannot be detected by the human eye. Detectors that are sensitive to UV light converts it into a form that we can see. A few reptiles, birds, and insects such as bumblebees can see UV light and bug zappers use it to lure them closer.

UVC Lighting Options

We currently offer three different options of germicidal light bulbs: Fluorescent tube, compact fluorescent and incandescent. They each come in two types, low pressure lamps and high pressure lamps.

Low pressure lamps are like the fluorescent lamps, with the most common germicidal lamp looking just like a fluorescent tube. Changes to the glass and the lack of fluorescent phosphor means the ultraviolet light passes through unmodified unlike fluorescents that produce visible light.

High pressure lamps are like the HID or incandescent lamps. They produce a broad-band UVC radiation and are used for industrial water treatment because they are an intense radiation source. They produce a very bright bluish white light.
