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.
7 Myths About LEDs
The lumen’s limits: why old measures of light output don’t always work for LEDs, and what to do about it
On the “rebound effect” in energy efficient lighting or why LEDs aren't like other energy efficiency
The brightness you see versus the brightness you read about: on light levels, LEDs, and the shortcomings of the lumen
The industry uses a measure called the "lumen" to measure light volume across light sources. Based on our installations, we believe the better quality the light, the "brighter" a lumen appears. Here we'll explore why we think the lumen fails to indicate brightness properly where LEDs are concerned and what we do about it.
