Those incandescent lamps have Wolfram in them. That stuff certainly doesn't sound friendly.
Wolfram (a.k.a. Tungsten) is a largely inert material. If you want to poison yourself with it, a 200 lb. man needs to eat more than one pound of the metal.
To compare, mercury is poisonous in micrograms. Here is one report:
A 1987 report described a 23-month-old toddler who suffered anorexia, weight loss, irritability, profuse sweating, and peeling and redness of fingers and toes. This case of acrodynia was traced to exposure of mercury from a carton of 8-foot fluorescent light bulbs that had broken in a potting shed adjacent to the main nursery. The glass was cleaned up and discarded, but the child often used the area for play.
The same Wikipedia article contains a large list of other cases related to mercury.
Ah, you have seen through the clever disguise. The fluffy white pure light.
But all along it was wolfram in sheep's clothing!
You must be kidding!
