Even if the lights are effective, I am skeptical enough of LED quality control that I don't exactly jump to trust that the ones I get aren't leaking out the side bands (off-color basically) and sending adjacent more harmful wavelengths into my eyes. Especially if those LEDs start to be sold on Ebay and come from who-knows-what factories (which there already are).
- ciphol 5y ago1) Doesn't an LED have only a single band gap, determined by its main materials, thus no "side bands"? 2) Even if other wavelengths are produced, they just need to be produced in lesser quantities than in say sunlight. 3) #2 will require regulation and enforcement, but so do numerous other consumer devices - did you worry about your CFL leaking mercury?
- supernova87a 5y ago1. Not if it relies on phosphors or dopants to achieve the desired emission profile. 2. I don't think that the standard for a safe environment at home or at work is that you are exposed to the wavelengths and intensities equal to direct sunlight?
- quantum_magpie 5y agoThe lamps aren't LED and you can't get to UV-C wavelengths in LEDs. Also 222nm is deep into the DNA damage spectrum so they aren't safe for living organisms anyway.
