Alexey Yurasov, a Doctor of Physical and Mathematical Sciences and Professor at the Nanoelectronics Department of RTU MIREA, highlighted the potential dangers associated with certain popular lamp types, offering a comparative analysis.
Professor Yurasov explained that LED lamps stand out due to the absence of toxic components. In stark contrast, fluorescent lamps contain mercury vapor, necessitating strict adherence to disposal regulations because their breakage is potentially hazardous to health. While fluorescent lamp bulbs are generally more robust, the mercury content remains a concern.
Incandescent and halogen lamps, however, are prone to breaking easily from falls of even a meter or light mechanical impact; their filaments can also be damaged by vibration, leading to premature failure.
He further emphasized that LED lighting provides illumination that most closely mimics natural light, contributing to better visual comfort and potentially reducing eye strain.
Yurasov also shared a simple method for assessing a lamp`s color rendering quality: hold a sheet of white paper and a vivid red marker under the light. If the red color appears grayish or yellowish, it indicates poor color rendering, and such a lamp should ideally be avoided for tasks requiring accurate color perception.
