How does Far-UVC light compare to UVC?

How does Far-UVC light compare to UVC?

The use of UVC light as a disinfection method has gained a lot of traction over the past few months since the start of the Coronavirus/COVID-19 pandemic. And, more recently, “Far-UVC” light has garnered attention as a safer alternative to traditional germicidal UVC light. The difference between Far-UVC and UVC lies in where each sits on the electromagnetic spectrum—and how much we know about it.

What you should know before purchasing germicidal UVC equipment

What you should know before purchasing germicidal UVC equipment

Whether or not a product will be effective against Coronavirus is dependent on a few factors: the length of time the virus is exposed to UV, the intensity of the irradiation, and the wavelength of the UV radiation. With that in mind, here are a few things to look out for when purchasing germicidal UVC equipment.

Anti-Covid Air: Bipolar Ionization vs. UVC for Coronavirus Disinfection

We've done a lot of research into options for the sanitation of air and surfaces, and here we'll try to distinguish between the two most popular pathways to battle the Coronavirus with technology: UV-C light, also known as germicidal UV light (GUV) and bipolar ionization (BPI).

Popular Disinfection Methods Used Against Covid-19

There are various types of disinfection/sanitation methods that can be used to help stop the spread of Coronavirus, with varying levels of safety and effectiveness. Here we'll review three: bipolar ionization, fogging, and germicidal ultraviolet radiation, or UVC light.

CDC Guidelines and UV light

CDC Guidelines and UV light

The CDC recommends a few solutions to lower the likelihood of transmission:

  • Increasing airflow by using portable high-efficiency particulate air filtration systems

  • Using natural ventilation when possible

  • Using ultraviolet germicidal irradiation as a supplement to help inactivate the virus

How UVC Light Kills the Coronavirus

How UVC Light Kills the Coronavirus

The kind of ultraviolet light that's used in germicidal light fixtures is UVC. UVC is one of three types of rays produced by the sun (visible light, ultraviolet rays, and infrared), but is blocked from reaching us by the Earth’s ozone. The wavelength of UVC is between 200 and 280 nm, and only UV lamps of this wavelength have been proven to inactivate the Coronavirus.

What's New in the 2020 energy code

The 2020 code is similar to the 2016 code of the same name, but every piece is a bit more stringent, all adding up to a better, more efficient building. The code includes things like insulation and fenestration requirements, whole building energy monitoring, more efficient lighting power requirements, and additional lighting controls.

First steps for LL97 Compliance

How do we push forward? For business and building owners, it’s solutions that make business sense. The crux of LL97 is reducing building emissions. The most effective way of reducing emissions is by saving energy across all areas of your building's consumption. This includes everything from heating and cooling to HVAC, building envelope, and lighting.

Lighting the way to workplace wellness in your office

Lighting the way to workplace wellness in your office

Lighting can often be overlooked as an area to incorporate wellness into a workplace, but it has way more to do with your health than you might expect. So what is it about lighting that is so crucial for creating a productive work environment? Well for one, poor lighting isn’t just uncomfortable, it’s unhealthy.

The ABCs of re-lamping: what "type" of LED is right for you?

The ABCs of re-lamping: what "type" of LED is right for you?

In the early days of your LED re-lamp project, you’ll need to determine whether you’ll be using a Type A, B, or C replacement. The differences in each stem from whether a ballast or driver is being used and how the LED is connected to the power source. How that power gets to your lamp depends on the type of fixtures and ballasts you already have in place.

The lumen’s limits: why old measures of light output don’t always work for LEDs, and what to do about it

The lumen’s limits: why old measures of light output don’t always work for LEDs, and what to do about it

When replacing one light source with another, you need a medium of exchange, and lumens exist to serve as that medium. However, LEDs may be the end for the old faithful lumen. In practice we’ve found it to be a significantly inaccurate indicator of brightness where LEDs are concerned.
