Question from YH
I plan to buy a heat lamp and put under the table where I usually seat (imitating the Japanese’s Kotatsu). Heat lamps emit infrared light. Is the light safe?
I was scared of the hydrogen lamp that I have been using for 4 years because it may emit radiation (even though the piece of glass is supposed to stop all the radiation). Is hydrogen lamp safe?
How about flourescent and incandescent light? I heard that fluorescent light also emits radiation, but I am not sure. Also it cannot be recycled…
Is incandescent light totally safe? I know that it uses 4 times more energy than flourescent lightbulbs… Thanks
