Radiometers, photometers, spectrometers and spectroradiometers are all used to measure light, but they operate in fundamentally different ways and have distinct advantages and disadvantages.
By Russell Bailey, June 2024 Abstract To properly characterise and
The solar reflectance and heat retention properties of materials are key factors that lead to increased temperatures in urban compared with rural environments. The metric developed to assess the performance of building materials is called the Solar Reflectance Index (SRI).
How do you determine the appropriate lighting in horticulture, and how do you validate its effectiveness—whether you’re a plant grower or a lighting product manufacturer?
In the realm of lighting, flicker isn’t just a mere oscillation of light; it’s the unsung hero dictating our visual comfort. Learn what flicker is and how to measure it.
Pro-Lite’s Robert Yeo reviews the metrology of displays and explains the problem of ambient light and sunlight readability.
