Ushio CF18DE/835 18W 3500K 1200lm 10000h Dimmable Fluorescent Bulb

Ushio 18W Dimmable Fluorescent Bulb

This 18 watt compact fluorescent lamp delivers 1200 lumens at a 3500K colour temperature. It is designed for fixtures that use electronic ballasts and supports dimming operation. The double tube design suits commercial and residential lighting where consistent output is required. A colour rendering index of 82 provides acceptable colour fidelity for general tasks.

Four-Pin Base for Electronic Ballasts

The 4-pin base connects directly to compatible electronic ballasts without a separate starter. This interface enables the dimmable function when paired with a suitable dimming ballast. The double tube construction keeps the lamp length compact for recessed or surface-mounted fittings. Installation is a simple push-and-twist action into the matching socket.

Check Ballast Compatibility Before Ordering

Verify that the existing fixture uses an electronic ballast rated for 18W 4-pin compact fluorescent lamps. Magnetic ballasts or 2-pin sockets will not operate this bulb correctly. Dimming requires a ballast specifically designed for dimming control. Buyers who need a different wattage, pin configuration, or non-dimmable lamp should select an alternative model.
