In a massive study of more than 80,000 adults, scientists have found a link between bright artificial light in the evenings ...

Pregnant individuals who sit for more than 10 hours daily face higher risks for adverse pregnancy outcomes, whereas about 7 hours of light-intensity activity daily is linked to a lower risk.

Accurate measurements of light intensity provide vital data for scientists and everyday applications. For example, precise values help optimize microscopy signals, trigger physiological processes in ...

Most people probably don’t think of everyday activities – such as hanging out the washing or putting away the groceries – as having an effect on their long-term health. But new research suggests that ...

Researchers have developed the first standard LED covering the full visible light, in collaboration with Nichia Corporation. LED and OLED lighting, which is generally called solid-state lighting (SSL) ...

The light intensity curves for LEDs, regardless of whether they are collimated with a lens or reflectors, follow a bell shaped curve (often referred to as a “Lambertian“ curve). The 50% intensity ...
