The MASTER LEDspot range of LED GU10 spotlights from Philips is designed to provide a viable and cost effective alternative to the outgoing halogen spotlights that are due to be phased out by the European Union next year. They are more efficient, more reliable and longer-lasting than those they are designed to replace, yielding a raft of savings throughout their lifetime, from instantaneous energy savings to reduced maintenance costs further down the line. The mains voltage GU10 pictured here uses just 3.7W but delivers the same light quality and brightness as a 35W light bulb. Additionally, the 2,000 hours rated lifetime of comparable halogen spotlights pales into insignificance when compared to the 25,000 hours of this LED version. LED technology is inherently more efficient than halogen light bulbs and ultimately gives off less heat, UV and IR, meaning that LED spotlights are much better suited to heat-sensitive applications related to food, organic materials and paintings. This particular version retrofits directly to existing GU10 fixtures and diffuses its light within a 36° beam angle. This spotlight lamp is traditionally known as a PAR16 with a GU10 2-pin twist and lock (10mm apart) base.
