Hi Lightbulbman I was just checking back on your address. When I was checking zipcodes with the USPS, it did not find it. I decided to do the Google Map on my Iphone. I found it there, The #2 Lafayette St. said 01608-2160. You have 01608-2159. I found out you are 3142 km ( 1952 miles)from here. Is that Apartment #41. If you live in an apt, where do you keep all your bulbs? :-) Didn't get any mercury vapors but the guy from the electrical business did have 3 smaller size but 175 W Metal Halide ones. Those do look like neat light bulbs. So I have them in the box anyways. The one I wanted to give to you from the hospital was a larger size. Perhaps that will have to go in another parcel if I send more sometime.
