Steiner now offers disinfectant lighting solutions from industry-leading manufacturers designed to supplement the disinfection of high-touch and high-traffic spaces by inactivating certain viruses and pathogenic bacteria (*see disclaimer below).
These technologies—including UV, 405nm, and 222nm wavelength options—are engineered to safely and efficiently reduce a broad range of harmful pathogens such as bacteria, mold, yeast, and fungi. When applied correctly, and in accordance with each manufacturer’s guidelines, disinfectant lighting can eliminate up to 99.9% of certain viruses and bacteria in occupied or unoccupied spaces. Featured solutions are available from trusted manufacturers like PURO Lighting, Current Lighting (Hubbell Lighting), Kenall, and Acuity Brands.
It’s essential to understand the differences between disinfection lighting spectrums to ensure safe and appropriate application. Some technologies are safe for use in occupied spaces, while others require the area to be vacant during operation. Common applications include hospitals, nursing homes, schools, fitness centers, restaurants, grocery stores, retail spaces, hotels, offices, public restrooms, and mass transit facilities.
Choosing the right disinfectant lighting solution requires consideration of your environment and usage needs. Steiner’s Lighting Technology Specialists are available to help you assess your space and recommend the most appropriate technology.

Featured Disinfectant Lighting Technology Solutions
PURO™ Lighting UV Disinfection Lighting
PURO™ Lighting’s Helo and Sentry products, powered by Violet Defense™ technology, use broad-spectrum UV light—including UV-C, UV-B, and UV-A—for fast, effective disinfection. Clinically tested and EPA guideline-aligned, these fixtures are proven to inactivate up to 99.9%† of bacteria, viruses, and fungi—including Norovirus, MRSA, and C. diff. PURO UV lights also demonstrate efficacy against Class 2 and 3 viruses such as coronaviruses, Influenza, and Ebola.
†Effectiveness is based on proper installation and runtime per manufacturer guidelines.
Helo™ Series: The Helo Series is the first known ceiling-mounted, high-intensity, full-spectrum UV disinfection fixture. Designed to deliver whole-room, clinical-level disinfection, Helo provides powerful, on-demand cleaning in a single cycle—ideal for spaces of any size.
Sentry™ Series: The Sentry Mobile Series delivers powerful, broad-spectrum UV disinfection in a highly portable format—ideal for reducing harmful pathogens wherever needed. Designed for easy mobility, positioning, and operation, Sentry products help eliminate up to 99.9%1 of bacteria and viruses in the space, while also limiting the growth of fungi2.
Kenall Indigo-Clean® Continuous Disinfection Lighting
Kenall’s Indigo-Clean® is a patented, clinically proven continuous disinfection technology designed to reduce surgical site infections (SSIs) and healthcare-associated infections (HAIs). It works by killing harmful bacteria and reducing their intraoperative transmission in real time.
Indigo-Clean combines 405nm indigo and white LEDs to emit narrow-spectrum visible light that provides both ambient illumination and disinfection. Unlike UV-based solutions, Indigo-Clean uses safe, visible light to continuously and automatically kill bacteria in the air and on both hard and soft surfaces—making it ideal for occupied healthcare environments.
405 Nanometer Antimicrobial Lighting
Hubbell Lighting’s SpectraClean™ luminaires provide continuous environmental disinfection by integrating antimicrobial technology directly into the lighting system. These fixtures automatically treat harmful microorganisms in the air, on surfaces, and on objects—without disrupting daily operations.
SpectraClean™ combines general illumination with narrowband 405nm visible light, leveraging advancements in lighting science and microbiology. This visible light technology continuously suppresses bacteria, mold, fungi, and yeast by inducing reactive oxygen species that accelerate cell inactivation—all while meeting ambient and task lighting requirements.
Available in a variety of form factors—including Contemporary Architectural Troffers, Lensed Troffers, Striplights, and Linear Vaportites—SpectraClean™ supports four customizable application modes. When paired with occupancy sensors and room controllers, the system can be automated based on room usage or pre-set schedules, offering an adaptable, low-maintenance disinfection solution for commercial environments.
222 Nanometer Far-UVC Lighting
Acuity Brands’ commercial luminaires featuring Care222® technology from Ushio America, Inc. offer a breakthrough method for reducing pathogens on surfaces throughout the day using filtered 222nm far-UVC light.
This advanced disinfection solution meets current ACGIH® safety guidelines for exposure to far-UVC light when used within defined parameters. Laboratory and clinical studies indicate that 222nm light can inactivate viruses and bacteria rapidly, at energy levels that are safe for use in occupied spaces—without harming eyes or skin.
Care222® modules are integrated into general illumination luminaires and operate using independently modulated pulses of disinfection light. Designed for both occupied and unoccupied environments, these fixtures require no special training to use and provide continuous, low-maintenance surface disinfection throughout the day.
All references to "disinfection" refer generally to the reduction of pathogenic bioburden and are not intended to align with any specific definition of the term as used by the U.S. Food and Drug Administration (FDA) or the U.S. Environmental Protection Agency (EPA). The Care222® disinfection technology integrated into Acuity Brands luminaires is not intended for use as, or as part of, a medical device.
