We got the A-shaped CFLs that have the cover over them and put them in our ceiling fan lights (fan is never on, only lights). Today my lovely DH found a cover on the sofa and him being so intelligent doesn't bother to worry about where it came from and sets it on the table. I find it a few mins ago and it turns out it broke off of on of the CFLs, which is still in the fan and still working. So only the cover broke off, does that make sense. I'm freaking out here....do I have to worry about mercury contamination. I've looked up n:vision (brand we got) and I know they use the least amount of mercury and use it in the form of solid amalgram pieces to decrease contamination but they only tell you about bulb breakage, not cover breaking off...the bulb itself is intact. Anyone have any useful info here? TIA!!!
