This type of bulb -a 2 prong - isn't the most common type of bulb in our home , but a 2 prong was what our entry, ceiling fixture came with. These new bulbs were purchased to replace the 2-prong florescent bulbs that I purchased when I originally purchased the fixture. Boy, what an improvement! With the old florescent bulbs it was difficult to see into the nearby closet. With these bulbs it is like having a light in the closet! A great and inexpensive upgrade!
