Their compact size enables them to be used in applications where space is limited and provides a consistent, even light appearance in fixtures. To help you find the right bulb for the right application, see Westinghouse's full offering of circular fluorescent light bulbs. Circular fluorescent bulbs are perfect for use in tabletop magnifying lamps, table lamps, floor lamps and ceiling fixtures, as well as, some ceiling fans where applicable. These light bulbs contain mercury. Dispose of according to local, state or federal laws.
