Medium Base Screw-In Interface Limits

The medium screw base determines which fixtures accept this bulb; appliances with candelabra, bi-pin or proprietary sockets cannot use it. Compact fluorescent technology requires a short warm-up period before reaching full brightness and may not operate reliably in very cold compartments. The 19W rating fixes the light output and power draw, so fixtures rated for lower wattage should be avoided. Dimming circuits and electronic controls not rated for CFL loads can cause flicker or premature failure.
