A direct LED replacement for long barrel halogen GU10 spotlight. This LED long barrel GU10 light bulb is constructed from a thermal plastic body to mimic the shape and size of long neck a halogen GU10 lamp. Features the latest LED SMD (surface-mounted diode) technology. It shares the same long necked spotlight body, GU10 cap and frosted lens as its predecessor, and even delivers the same cool white light within a 100° beam angle. Despite the similarities, this long barrel LED GU10 spotlight light bulb is much more efficient and much more durable than its compact fluorescent or halogen brother. Where the LED lasts upwards of 25,000 hours and requires just 4.9W to produce 280 useful lumens a halogen long-barrel GU10 would consume 50W to produce the same level of brightness. The light bulb's distinctive long-barrel design adds an additional 25mm to the length of its body, enabling it to fit deeper downlight fittings more comfortably than standard GU10 light bulbs. Suitable for use in fire-rated downlights. Compatible with both leading and trailing edge dimmers*. *This long barrel LED GU10 light bulb is compatible with most dimmer switches, but please refer to the manufacturers website for an up-to date list of compatible dimmer switches.This long barrel LED GU10 spotlight lamp is traditionally known as a PAR16 with a GU10 2-pin twist and lock (10mm apart) base.
