This is a Prolite 6w LED 110v-240v R7s 78mm in a 3000k warm white colour, ideal for replacing 60w halogen R7s lamps within floodlights. The Linear R7s has dual voltage capabilities running from 110v - 240v, commonly used in construction sites at 110v within floodlights to applications using mains 240v such as corridors and gardens. Boasting also a lumen output of 800 lumens and an average lamp life of 40,000 hours. These lamps are slightly larger in diameter than the older style linear halogen lamps, although most fittings which would have taken linear halogen lamps would also have a shatter proof casing to offer protection if the halogen lamp shattered. The 78mm lamp is also non dimmable and if they are dimmed it will cause damaged to the lamps and would not be covered under the manufacturers 1 year guarantee. Dimensions: 78mm x 20mm
