Dimensions exactly as described. Perfect for my c9 wires. The top ones are the bulbs I bought on this list (the bottom ones are elsewhere). Although the ones on this list don't appear as bright as the others **in the photos**, the ones on the list are much brighter than the others **in real life**. They can be lighter because they are faceted. The lower ones are smooth. An added bonus is that the lamps on this list are not hot at all, while with the other lamps I could feel the heat radiating into my face immediately. The ones on this list are also taller (slightly taller but slimmer). Very happy with my purchase. Very important!
