Lead paint isn't a big issue but asbestos is. My uncle never thought much about it till he found he had mesothelioma at 55. I would never screw around trying to deal with asbestos.

They never last that long. I replaced all the recessed lights in my house with LEDs that were supposed to last 10 years, within 1 year 2 of the 24 had died and the shipping and handling to get the replacements under warranty was more than buying a new bulb. LEDs are a fucking scam.
