Eiko 15356 - H39KB-175 Mercury Vapor Light Bulb

 (1 customer review)

Great! service, but the bulbs don't seem to last as long as expected. I had other brands that would light my flag pole for a year or more. These seem to have an average of 6-7 months. I had a bought a box and consistently have change them within that period frame. I probabbly will buy again, simply because of the price. It outweights the high priced ones and at the end it is a better value - but not by much.
