Cerise365 and DAYSIM
Cerise365™ and DAYSIM are daylighting analysis software programs that perform climate-based annual daylight simulations, including the calculation of annual daylight metrics. This white paper compares their performance in terms of accuracy and calculation times....
Specifying LED Colors for Horticultural Lighting
When the first high-pressure sodium (HPS) lamps were introduced in the late 1960s, they were quickly adopted by commercial greenhouse operators as a means of providing supplemental electric lighting. This made it economically possible to grow vegetables and flowers...
Filtered LEDs and Light Pollution
The problem is astronomical — the blue light emitted by LED roadway luminaires has been shown to contribute to light pollution, especially when cool white LEDs are used. Blue light is preferentially scattered by air molecules, and so the higher the correlated color...
Ultraviolet Radiation Terminology
In Ultraviolet Radiation Terminology, SunTracker Technologies' Senior Scientist, Ian Ashdown dares to get pedantic about how we describe ultraviolet radiation. Do the terms we use really mean what we think they mean? Could we be describing them more accurately?...

We are proud of Ian Ashdown, our Senior Scientist, for sharing the wealth of knowledge he has with the University of British Columbia Computer Science students. SunTracker believes it is important to share knowledge and mentor young minds contributing to a brighter...
Climate-based Annual Daylight Modelling for Greenhouses with Supplemental Electric Lighting
Recent advances in LED-based luminaire design have enabled greenhouse operators to temporally control both the photon flux density (PFD) and spectral irradiance incident upon the plant canopy. However, it is difficult to predict the performance and benefits of these...
