Lumacept
What is Lumacept™?
Lumacept™ is a coatings technology developed for use with UV-C disinfection devices. Standard paint and wall coverings absorb 93-97% of the invisible germicidal UV-C light. Surfaces not in direct “line-of-sight” of the UV-C device are shadowed, resulting in less disinfection and very long disinfection times. The UV-C light that reaches shadowed areas has to reflect off surfaces like walls and ceilings, and with each bounce most of the remaining UV-C light is absorbed, leaving almost nothing for the shadows. With patented Lumacept™ germicidal UV-C remains, even after multiple bounces, to reach the nooks and crannies where germs can hide.
The Benefits of Lumacept™
Rapid Disinfection: In a patient room with walls painted with Lumacept™ where UV-C disinfection times were based on the time needed to treat the shadowed areas**, Lumacept™ has been shown* to reduce disinfection times by 80% without any loss in disinfection effectiveness! Adding Lumacept™ to the ceiling and other surfaces further reduced disinfection times.
Better Disinfection: In rooms painted with Lumacept™ where UV-C disinfection times are not reduced, the surfaces not in line-of-site of the UV-C device will see an average of 14 times more UV-C light as the same shadowed surfaces in a room without Lumacept™.

** Some UV devices have recommended treatment times which are calculated for only the direct line-of-sight surfaces and do not take into account the necessary time to treat the shadows.
The Benefits of Lumacept™
-Jelden, et al. J Occup Environ Hyg.
Coating hospital room walls with UV-reflective paint enhanced UVGI disinfection of nosocomial bacteria on various surfaces compared to standard paint, particularly at a surface placement site indirectly exposed to UVC light.
-Tande, et al. Infection Control & Hospital Epidemiology
The use of UV reflective paint led to greater uniformity in the intensity because significantly more light reaches indirect surfaces.
-Rutala, et al. Infection Control and Hospital Epidemiology
The use of the reflective coating significantly improved microbial reduction. This allows UV-C disinfection technology to be more easily integrated into healthcare facilities where occupancy is high and fast patient room turnaround time is critical.
UVC-Max
UVC-Max can achieve more than 10X the UV-C reflectivity of standard paint. It is intended for those customers who want the most UV-C reflective formulation available in order to maximize effectiveness or minimize treatment time.
UVC-Bright
UVC-Bright can achieve more than 7X the UV-C reflectivity of standard paint. It is intended for those customers looking to balance cost and performance. For many applications, including the disinfection of hospital rooms using a sensor-based UV-C device, UVC-Bright is our most frequently recommended option.
We can easily match both UVC-Max and UVC-Bright to your existing colors.
Lumacept looks and feels just like traditional interior water-based paints. It can be rolled, brushed, or sprayed. Thinning with water is fine. However, other additives must be avoided as they may affect the UV-reflective properties.
Lumacept is shipped directly from our facilities. The ordering process is simple:
1. You specify a color, often a standard color from a national paint manufacturer, or you send us a color sample to match.
2. We match the color and send you a sample to approve.
3. After you approve, we produce and ship your order. Contact us for more details or to discuss your application.
Our simulation technology designed to take the guesswork out of establishing UV-C treatment protocols.
-Visualize how well your UV device is getting light into the areas that need to be disinfected
-Quantify the effect of device placement and room configuration on the UV dose received by surfaces of interest
-Optimize your protocol to achieve the most effective disinfection in the shortest time To learn more about LumaSim, please contact us.
The images above are renderings produced from a LumaSim 3D model of a patient room. The image on the right is of a room modeled using UV-reflective walls, while the image on the left is of a room with traditional paint. LumaSim can be used to create these visualizations of UV intensity and also to quantify the intensity for prediction and optimization.
