Lighting, Displays & Radiometry
Light measurement plays an important role in understanding how lighting and optical technologies perform. StellarNet spectrometers and radiometers capture detailed spectral information from LEDs, displays, lasers, and other light sources. This data can be used to evaluate color, spectral irradiance, intensity, and changes in light output. Solar irradiance measurements can also help researchers study natural and simulated sunlight. Whether testing a new display or characterizing an LED, StellarNet provides flexible tools for collecting reliable optical measurements in the lab and in the field.

Lighting the Way to Better Welfare: Spectrometer Use in Zoos
Light is the essence of life, shaping the evolution of every living creature on this planet. By better understanding light, we better understand life itself — a crucial mission for zoos, whose primary role is not just to care for animals but to ensure their well-being. Animals rely on sunlight for a multitude of reasons, from birds using UVA rays to judge mate quality to reptiles absorbing Infrared A and B to regulate their body temperature.
Why Turtle Safe Lighting Matters for Sea Turtle Survival + An Interview with FWC Experts
Artificial lighting along coastlines is a well-documented threat to sea turtle populations. Species such as the loggerhead sea turtle and green sea turtle rely on natural light cues for nesting and hatchling orientation. Disruptions to the spectral composition and intensity of coastal lighting can lead to disorientation, reduced nesting success, and increased mortality.
