A: Hello, DiamondGirl. This lamp should fit into a standard fixture. This A19 bulbs are 4.4 inches in length and the A21 lamps are 5.16 inches in length. Thank You GE Lighting a Savant Company.
A: Yes. The bulb is approximately the same size as a 60 watt incandescent bulb so it will fit. The purpose of the original rating takes the heat and power requirements into consideration. An LED bulb uses substantially less power and generates far less heat (almost none) than a 60 watt bulb, so you will be fine.
A: Hello, Jessenia. Unfortunately, the E12 size is different than the medium size that is on these bulbs. You will want to look for E12 or Candelabra in the description/specifications of the bulb to use for the fan you have. Thank you. Scott GE Customer Service
