Westinghouse T6 40 Watt Warm White (3000K) GU10Q Base Light Bulb 3734000

Circular Fluorescent light bulbs operate on preheat or instant start systems. These circular tubes will provide the same amount of light as an incandescent bulb while using 3 to 4 times less energy. 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 table-top 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. For more on clean up and safe disposal, visit epa.gov/CFL.
