The risk depends on what type of bulb you are dealing with. Compact fluorescent lights contain a small amount of mercury, which can be toxic if it enters your body (see References 1). LED lights have been found to contain arsenic and lead, also at very low but potentially toxic levels (see References 2).

The study found that exposure to light-emitting diode (LED) lights can cause irreparable harm to the retina of the human eye. Once the retina cells are destroyed by prolonged and continuous exposure to LED rays, they cannot be replaced and will not regrow, Think-Spain.com reported.
