Most people with ES are sensitive to chemicals, so beware of this issue. I just found out after getting a batch of terribly smelling bulbs, but potentially even bulbs that don't smell are offgassing pretty bad stuff that you can't even smell!
For GU10 bulbs there are glass body bulbs that I believe should be quite good.. but no idea for normal bulbs. Incandescent is glass/metal, so no problems like this.
