Features & Benefits

  • First UL-Certified direct LED UVC luminaire for occupied spaces
  • Helps in the inactivation of aerosolized viruses as an additive measure in a total disinfection plan
  • Low dosage UVC device is designed for continuous 24 operation in areas where people are present and operates without the need for controls
  • Complies with human exposure limits per IEC 62471 Photobiological Safety of Lamps and Lamp Systems standards and American Conference of Governmental Industrial Hygienists (ACGIH®) TLVs® guidelines when installed as directed
  • Compact size (5” diameter x 2.1” width) is similar in appearance to a smoke detector and allows integration into the existing ceiling infrastructure for minimum ceiling height of 8.5’
  • UVC is invisible to the human eye and the distributed UVC pattern covers approx. 50 sq ft at typical mounting height of 10’

Current is certified through UL’s Data Acceptance Program (DAP) to perform testing to the IEC 62471 safety standard with products meeting IEC 62471 Photobiological Safety for Lamps and Lamp Systems standard and American Conference of Governmental Industrial Hygienists (ACGIH®) TLVs® for human exposure to UV. The LPU UVC device is the first UL-Certified direct LED UVC luminaire for occupied spaces. In addition, Current conducts third party testing to substantiate our claims and validate our predictive models. *See Test Results for supporting detail.


Flexible LED solutions for 24-hour occupancy with UV dosage designed to operate below human health exposure limits providing an added layer of protection along with masks, hygiene and social distancing.

Ease of Operation

The LPU is compact in size (5” diameter x 2.1” width) and similar in appearance to a standard smoke detector. Simple operation does not require additional controls and includes user friendly indicator lights showing operation status.

Make an Informed Decision

  • UV radiation can pose a risk of personal injury. Overexposure can result in damage to eyes and bare skin. To reduce risk of overexposure, equipment must be installed in accordance with manufacturer's site planning and application recommendations, including minimum ceiling height restrictions.
  • UV solutions are intended for common high traffic spaces and not recommended for dwellings or home use.
  • Installation of the devices should be performed by qualified professionals as detailed in Current's installation guide.
  • To allow for occupancy during use, Current products comply with UL 8802 Outline of Investigation for UV Germicidal Equipment and Systems, IEC 62471 Photobiological Safety of Lamps and Lamp Systems standards, and American Conference of Governmental Industrial Hygienists (ACGIH®) TLVs® guidelines over an 8-hour period when installed as directed.
  • Current's UV products are meant to be used in conjunction with other protective measures like manual cleaning and the use of proper PPE. They are not a substitute for other measures.
  • Current products are not intended for use as a medical device.
  • If combining two or more UV solutions, whether from Current and/or other manufacturers, please consult a trained product application representative to ensure the total irradiance (UV dose) does not exceed recommended human exposure limits. To the extent UV solutions are combined, it may impact inactivation rates.

UVC Testing, Lab Results & Notes

GE Current, a Daintree company, has completed room-scale tests of its 365DisInFx® UVC disinfection technology LPU series devices that show reduction of the aerosolized viruses SARS-CoV-21 (the virus that causes COVID-19), and bacteriophage MS22.

Applying photobiological science and mathematical modeling to the results of device testing and published literature, continuous operation of a properly installed array of 365DisInFx® LPU Gen 2 devices is predicted to provide 90% (1-log10) inactivation of aerosolized SARS-CoV-2 in the first hour1 or less of exposure and 99% inactivation (2-log10) in 2 hours or less of exposure in most spaces when configured for an 8-hour or greater Permissible Exposure Time (PET) as defined in IEC 62471 – Photobiological Safety of Lamps and Lamp Systems standards. Current continues to conduct additional supporting experiments.

1Testing with the SARS-CoV-2 using LPU devices with prototype refractive optics resulted in 90% inactivation of the aerosolized virus within 2 hours. This testing was then used as the basis for photobiological science and mathematical modeling. The test was conducted in an 8-by-20-by-8-foot room equipped with twelve LPU devices using prototype refractive optics, configured for 8-hour Permissible Exposure Time (PET) at head height (7 feet). SARS-CoV-2 Isolate USA-CA1/2020 was used in this testing, and results are expected to be applicable to other SARS-CoV-2 isolates or strains, including B.1.617.2 (Delta) or other Variants of Concern or Interest, as well as to seasonal human coronaviruses.

2Testing with the bacteriophage MS2 resulted in 88% inactivation of the aerosolized virus within 4 hours. The test was conducted in a 10-by-10-by-8-foot room equipped with seven LPU prototype devices, configured for a 4-hour Permissible Exposure Time (PET) at head height. Bacteriophage MS2 is a nonenveloped virus that is commonly used as a surrogate in testing for viruses that are pathogenic to humans. It is particularly useful as a surrogate whereas published scientific testing and literature supports that bacteriophage MS2 is more resistant to UVC than certain enveloped viruses such as coronaviruses and influenza.
