I don't know about anyone else but 3 yrs ago I developped a horrid rash that couldn't be controlled. I was sent to a top specialist who took one look after reading my chart and immediately asked if I was using or working anywhere that I was exposed to these bulbs. So happens that one place where I had to work had these bulbs in the room. I was told to never go near them again, got a scrit for the rash and I changed the bulbs to regular bulbs after explaining why I had to . I think a month or so later the rash was gone.Seems it was affecting my immune system in the worst way. We have none in our home and we are buying all the regular bulbs we can find as they're really going off the shelves fast.
