LED Measurement at DelphiTech – Customer Spotlight
A StellarNet SpectroRadiometer enables DelphiTech to ensure quality, quantify new products and analyze competitive products. Rodney McInnis, CEO of DelphiTech, has been manufacturing high-end LED lighting for the outdoor home lighting industry for over 15 years.
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.
