Revolutionizing Germicidal Light UV-C Technology

PURO Lighting’s Helo and Sentry product lines, powered by Violet Defense® technology, represent a significant breakthrough in germicidal protection. PURO Lighting products use a powerful, broad-spectrum light, including germicidal UV-C Technology, UV-B and bactericidal UV-A to optimize their efficiency. UV-C is most traditionally referred to as germicidal UV light with the ability to kill bacteria, viruses, mold, and fungi.

UV-A and UV-B light causes oxidation of proteins and lipids causing cell death.

Broadband UV lamps have also been shown to inhibit photoreactivation, the process that can result in self-repair of damaged microbes.

Is UV-C Technology Light New?

Not at all. Over 140 years ago, scientists Downes and Blunt discovered the antibacterial effects of sunlight. They determined that shorter wavelengths of the solar spectrum were more effective at neutralizing bacteria. It is now widely known that there are substantial germicidal and bactericidal effects from UV-C, UV-B, and UV-A light spectrums.

What’s New About PURO UV Lighting Products?

PURO Lighting, with patented Violet Defense technology, uses a pulsed xenon light engine that sends out a high-intensity beam of UV along with visible light when it flashes. It’s a full-spectrum UV, so it produces UV-C and UV-B, which are germicidal, and UV-A, which is bactericidal. It even produces bacteria-killing violet blue light. The lenses, made of a UV transmissive polymer, are in direct and immediate contact with a Xenon lamp, allowing significant UV energy transmission, without the fouling that occurs over time with non-UV transmissive lens materials.

PURO UV Lighting products kill today’s Coronavirus.

How Does UV Light Kill Germs and Viruses?

Ultraviolet germicidal irradiation (UVGI) is a disinfection method using short-wavelength ultraviolet C and B to kill microorganisms, germs, pathogens and viruses by destroying nucleic acids and disrupting their DNA. UVGI is used in a variety of applications such as food, air, surface and water purification.

Disinfection On Demand.
Any Room. Any Size. Any Time.

We’ve packed innovative, patented and powerful UV light technology into all PURO Lighting products to disinfect your spaces on demand — whether it’s protection from above or flexible, mobile protection to fit any space.

This powerful, groundbreaking design has enabled miniaturization of high intensity, broad-spectrum UV, enabling us to offer a fixture small and lightweight enough to mount in a ceiling or wall, and allowing us to create one of the most affordable and maneuverable mobile units available.

Independent labs have certified that PURO Lighting UV Disinfecting fixtures work. Powered by Violet Defense technology, PURO Lighting products have been independently and thoroughly tested by an ISO 17025 Accredited Testing Laboratory.

Proven to Inactivate SARS-CoV-2

In November 2020, two independent studies have conclusively confirmed that PURO UV Disinfection Lighting’s Helo F2 pulsed Xenon light unit effectively inactivates up to 99.99% live SARS-CoV-2 virus on glass, stainless steel, plastic and N95 respirator mask material.

Clinical Summary

Clinical lab testing showed that our fixtures kill up to 99.9% of MRSA, E. coli, Salmonella, and Norovirus at distances as far away as 3 meters.
