Decreasing UV exposure from fluorescent lights
Since CFLs are designed to provide general illumination, the majority of the light emitted by CFLs is localized to the visible region of the spectrum (approximately 400-700 nm in wavelength). In addition, typical CFLs emit a small amount of UVB (280-315 nm), UVA (315-400 nm) and infrared (> 700 nm) radiation. See more CFLs are a type of fluorescent lamp. Many models of CFLs are available that are designed to replace traditional incandescent bulbs.

WebApr 12, 2024 · Here, we propose and experimentally realize a photon-recycling incandescent lighting device (PRILD) with a luminous efficacy of 173.6 lumens per watt (efficiency of 25.4%) at a power density of 277 watts per square centimeter, a color rendering index (CRI) of 96, and a LT70-rated lifetime of >60,000 hours. WebUltraviolet (UV) radiation is a form of non-ionizing radiation that is emitted by the sun and artificial sources, such as tanning beds. The beneficial effects of UV radiation include the production of a vital nutrient, vitamin D; however, overexposure may present risks. Sunburn, premature aging, and skin cancer are all risks to overexposure. WebIncandescent bulbs do emit UV rays but in very small amounts and therefore are impossible to have any negative consequences to one’s health.
