Ultraviolet germicidal lamps can destroy bacteria, molds, yeast, and viruses.
Ultraviolet energy cannot be detected by the human eye. A bluish light will be visible through the filter of your lamp. This is due to the emission of visible light from the tube. The special filter eliminates most of the visible light interference.
What is ultraviolet light?
Ultraviolet light (UV) is the part of the electromagnetic spectrum that is adjacent to and greater in energy than visible light. The ultraviolet spectrum extends from 180 to 400 nm and is divided into three general categories: shortwave, midrange, and longwave. Ultraviolet energy is just shorter in wavelength than visible light and can be divided into three groups:
The ultraviolet energy nearest to the visible light range (commonly called black light), activates fluorescence in numerous natural substances and manufactured materials
The ultraviolet energy representing the shortest wavelengths found in sunlight, causing sunburn and used to fluoresce certain substances more effectively than shortwave or longwave ultraviolet light.
The ultraviolet energy farthest from visible light, shorter than rays in sunlight, and primarily noted for its ability to fluoresce minerals for chemical analysis, and for its germicidal effects. A shortwave ultraviolet light in the range of 280 to 100 nm can help kill mold and prevent its growth.
Stuart ™ handheld ultraviolet lamps
The Stuart series of lightweight, handheld lamps offer UV wavelengths of 365 and 254 nm, or a combination of the two. They’re cordless and use 12 VDC rechargeable batteries. They can sustain three hours of continuous use or about 500 intermittent uses when fully charged. The models equipped with an automatic safety switch prevent harmful exposure to UV radiation if the lamp is turned upside down.
Compact short/long-wave lamp
This compact, short/long-wave lamp comes with two 4-watt tubes (254 and 365 nm). Each tube produces a distinct wavelength; no mixing of primary UV ranges occurs. Lamp includes a 2″ x 3″ filter with up to 5000 hours filter life and a 7-ft, two-wire cord with on/off switch (115 VAC model has a plug).
UV germicidal lamp
This UV germicidal lamp prevent contamination in your research laboratories, food factories, and white rooms with these germicidal lamps. They emit 254 nm UV light that is efficient in the destruction of bacteria, molds, yeast, and viruses. Tube life is approximately 2000 hours. Replace starter every time you replace tubes.
