Vitamin D lamp: It doesn't seem to have any encyclopedic value as currently presented.  Bensci54 ( talk ) 17:21, 12 May 2023 (UTC) [ reply ] Speedy Delete , no sources and to provide any meaningful content would need to be nuked .  UV-B lamps pretty much covers all of it anyway.  PalauanLibertarian 🗣️ 17:46, 12 May 2023 (UTC) [ reply ] UVB lamps are lamps that emit wavelength of 280-320 nanometer.  Until few years ago there were no UVB LED lamps.  The only lamps in the market were fluorescent uvb lamps.  They were limited by the phosphore inside the glass.  There is no phosphore that can emit 297 nanometer, that is the most suitable for vitamin D3.  Lately LED lamps were developed, and with the new technology it is possible to reach any wavenegth.  Experimenting with them found that they are much better than the fluresncent UVB lamps.  The most known one is the fluorscent lamp of sperti.  It was found that the upper part of the UVB, 310-320 nanometer, reduces the vitamin D3.  Thus a full spectrum 280-320nm UVB lamp is not suitable for Vitamin D increase.

This is in order to educate that the fluoresent UVB lamps are simply not suitable for vitamin D3.  Just like if you tune the FM radio to the wrong frequency.

In 2023, everyone knows that we are not a web host .  That LED lamps used to facilitated Vitamin D production are "newly developed", "lately", and didn't exist "a few years ago" is a combination of neologism , promotion , and original research .
