Products

Light Sources and LightTech offer high-quality standard germicidal lamps in both ozone free and ozone generating solutions. The type of fused quartz used to make the body of the germicidal lamp determines the emission of the wavelength of the UV energy.

 "L" or “Low ozone” generating lamps transmit up to 90% of their energy at the 254nm wavelength and typically utilize a doped fused quartz that blocks the emission of 185nm energy.

 "VH" or “Very high ozone” generating lamps are produced using clear fused quartz which allows for the  transmission of energy at both 185nm and 254nm wavelengths. The 185nm energy reacts with the oxygen in the air to produce ozone. In applications where moderate amounts of ozone may be required, we can splice the two types of quartz together to form a custom "L" to "VH" ratio according to the customer's specific requirements.

UV-Action
 LightSources & LightTech's low-pressure, mercury-arc germicidal lamps are specially designed to produce the highest amounts of uv radiation - where 90% of energy is typically generated at 254nm. This radiation is very close to the peak of the germicidal effectiveness curve of 265nm, the most lethal wavelength to microorganisms. (see graph).
Our germicidal lamps are used extensively in the
air and water purification markets and have been utilized in applications such as food and beverage, medical, HVAC  (Heating, Ventilation and
Air Conditioning), pharmaceutical and the semiconductor sterilization industries.

Our germicidal lamps are essential components
in the drinking water, wastewater and ground
water remediation industries as well.

Ozone Action 

• "VH" (or Very High ozone producing lamps) generate energy at 185nm in addition to the 254nm wavelength.
• The UV emission at 185nm produces abundant amounts of ozone in air. Ozone is an extremely active and effective oxidizer, destroying microorganisms as well as acting as a deodorizer.
• A primary advantage of the ozone generated by our UV germicidal lamps is that it can be carried through the air into places not easily reachable by direct UV exposure.
