UVC Germicidal Hand Lamp

Kill bacteria and viruses on surfaces in seconds, without the need for chemicals

High output UVC germicidal lamp for disinfection of surfaces and areas difficult to reach with fixed mount UV lamps.

  • A 2-second exposure provides a 99% reduction of SARS-CoV-19
  • High UVC output at 254 nm
  • Rapid disinfection of surfaces and equipment
  • Contains UV 400W Mercury (Hg) bulb
  • Includes power supply

Current uses include disinfection of hospitals, care homes, surgeries, schools, nurseries, transport, equipment, incoming packaging and more.

Please note: UVC is extremely harmful to the skin and eyes. The operator must wear a full UV protective face shield (supplied) along with gloves and full protective clothing. It should be used when no other persons are present unless also wearing PPE.

UV exposure calculations

The following information is only applicable to the UVC Germicidal Hand Lamp, manufactured by UV Light Technology Limited. All UV-C irradiance measurements were taken at 200 mm distance from the lamp.

When comparing to independent research, conducted between Signify and Boston University, we can calculate the exposure time required to achieve a particular kill rate of SARS-CoV-19 by dividing the UV-C irradiance measurements taken into the UV-C dose levels stated in the Press Release from June 16, 2020.

UV-C irradiance values

Maximum Centre of beam: 50 W/m2
Average A4 area: 37.5 W/m2

UV-C dose requirements

UV-C dose required to kill 99% of SARS-CoV-19: 50 J/m2
UV-C dose required to kill 99.9999% of SARS-CoV-19: 220 J/m2

UV-C exposure times

Exposure time required to kill 99% of SARS-CoV-19: 1.33 seconds
Exposure time required to kill 99.9999% of SARS-CoV-19: 5.87 seconds

Excerpt from Press Release, June 16, 2020 (units converted from mJ/cm2 to J/m2)

Since the start of the SARS CoV-2 pandemic, Dr. Anthony Griffiths, Associate Professor of Microbiology at Boston University School of Medicine and his team have been working on developing tools to support scientific advancement in this field.

During their research, they have treated inoculated material with different doses of UV-C radiation coming from a Signify light source and assessed the inactivation capacity under various conditions. The team applied a dose of 50 J/m2, resulting in a reduction of the SARS-CoV-2 virus of 99%. Based on the data, it was determined that a dose of 220 J/m2 will result in a reduction of 99.9999%.

“Our test results show that above a specific dose of UV-C radiation, viruses were completely inactivated: in a matter of seconds we could no longer detect any virus,” said Dr. Anthony Griffiths. “We’re very excited about these findings and hope that this will accelerate the development of products that can help limit the spread of COVID-19.”
