Is it normal for LED lightbulbs to hiss?
I put a "Utilitech Pro #0382623" 75W equivalent LED bulb from Lowes Hardware in the light by my bed and it hisses. It makes a soft "white noise" type of hiss that I can hear when my head is ear it. The sound isn't unpleasant. However, on the web one finds reports of accidents such as: http://www.saferproducts.gov/ViewIncident/1222032
