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....

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...

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...

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...

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...

In celebration of International Woman’s Day, SunTracker congratulates Rebecca Thomson for receiving our 2020 Scholarship! Congratulations Rebecca!! We wish you the greatest success with your studies and your future! We are very happy we were able to assist you!...

Supplemental electric lighting for greenhouses may be essential for extending the growing season in northern climates, but it comes with a not-so-hidden cost: environmental light pollution. The consequences of this pollution may range from irate neighbours in rural...

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...

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...
