Spherical Irradiance and Aerosols

Lighting designers will be familiar with the illuminance of a planar surface, which is measured in lumens per square meter (or foot). The irradiance of a planar surface by a germicidal radiation source is conceptually the same, except that it is measured in watts per...

Designing an Ultraviolet-C Disinfection System

Designing an Ultraviolet-C Disinfection System

There is a newcomer on the block that has gained considerable media attention: far-ultraviolet excimer lamps. Recent medical studies have indicated that, unlike 254 nm radiation, the 207 nm and 222-nm “far-UV” radiation emitted by excimer lamps is likely harmless...

Our Food Security:

Recent public health events have highlighted the need for food security in local communities. In northern (and less hospitable) climates like Canada long term, year round food growth will depend on indoor facilities such as greenhouses, vertical farms (plant factories), and hybrid facilities. Proper lighting is critical for these facilities to successfully produce the necessary quality and quantity of food to sustain the population at a reasonable cost. SunTracker has developed CAD modelling tools to allow the horticultural industry to assess and specify the most efficient and effective commercial lighting for the horticulture industry, lighting that is critical for the sustainability of food security.
