WebMar 8, 2024 · Blue Light Exposure from Fluorescent Lights. Different light sources can expose us to different amounts of blue light, and this amount can vary significantly … WebFor a fluorescent light to work there is a filament that heats or a high voltage that ignites an arc in the mercury vapor that then generates an ultraviolet light. The coating on the tube fluoresces and you now have visible light.

WebIncandescent: filament gets hot and emits light; Fluorescent: UV rays cause phosphors to emit visible light; Laser: excited atoms of a solid, liquid, or gas emit photons of coherent light; Neon: excited gas atoms emit light when they drop back down to a lower energy level; Sodium-vapor: a gas mixture ionizes, vaporizing sodium and producing … WebA study in 2011 also found evidence that the transition from incandescent to fluorescent lighting had a big impact on eye health (1). Fluorescent lighting above 4000K is dangerous for the eye, and at 6000K it can cause damage to the retina. Conventional LEDs that emit high-intensity blue light also have a major impact on eye health.
WebThe UV radiation found in fluorescent lighting is present in two forms: UVB and UVA. UV radiation has long been known to cause a myriad of health problems. In the 1992 edition of the American Journal of Epidemiology, it was found that fluorescent lights emit “10-30 times” more UVB radiation than the sun does.
