I was thinking since my Aero Garden has LED's and I am growing fresh Herbs on the counter do the LED's produce UV Light? So seems like they do. But you wouldn't want to use them for heating as it will not really work well.
Some in the lighting business have stated that LEDs do not produce UV radiation. However studies have shown that standard LEDs do create a small amount of UV. That said, the amount of UV they actually emit is even less. This is due to the phosphors within an LED lamp that convert the Ultraviolet light to white light.Jun 21, 2016

So basically, are you saying that LEDs do not matter much unless you would have them on all of the time near your DIY supplies?
