Fluorescent bulbs contain mercury, a toxic substance. The United States Environmental Protection Agency (EPA) provides safety guidelines for how to clean up a broken fluorescent bulb. [17] Mercury can be harmful to children and developing fetuses, so children and pregnant women should avoid being in the area whilst a broken bulb is cleaned up. [18]
There is evidence that compact fluorescent light can worsen the condition. With the autoimmune disease lupus, exposure to compact fluorescent lamps will induce disease activity in photosensitive SLE patients. There is evidence that actinic prurigo is worsened by compact fluorescent light. This disease affects 3.3% of the general population.
Fluorescent light bulbs and tubes internally produce ultraviolet light. Normally this is converted to visible light by the phosphor film inside a protective coating. When the film is cracked by mishandling or faulty manufacturing then UV may escape at levels that could cause sunburn or even skin cancer. [53] [54]
A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, to produce ultraviolet and make a phosphor coating in the lamp glow.
However, a faulty fluorescent lamp can flicker at a much lower rate and trigger seizures. [medical citation needed] Newer high-efficiency compact fluorescent lamps (CFL) with electronic ballast circuits operate at much higher frequencies (10–20 kHz) not normally perceivable by the human eye, though defective lights can still cause problems.
Visible light (what’s emitted by a fluorescent lightbulb or one of those trendy LED face masks you may be seeing all over social media) can be important for some people—we’ll get to who in a ...
A broken fluorescent tube will release its mercury content. Safe cleanup of broken fluorescent bulbs differs from cleanup of conventional broken glass or incandescent bulbs, avoiding the use of vacuum cleaners, in favour of sticky tape to recover small particles, and ensuring that fans and air conditioning are turned off.
"The potential dangers of using at-home LED masks include headaches, eye strain, sleep disturbances, insomnia and mild visual side effects," she explained.
