This is a Bright Source 30w LED corn light with an ES (E27) cap, ideal for replacing Metal Halide and SON lamps. This lamp is an ideal alternative to a 50w SON/MH, offering energy savings of 40% and a lumen output of 3900 lumens. These lamps are often used in warehouses and factories as well as being used to light outdoor spaces in applications such as street lighting or in car parks and other outdoor areas. The 30w corn lamp has a colour temperature of 6000k meaning they are great for use in areas with CCTV coverage as this gives off a crisp white colour rather than the yellow glow of a SON lamp. They have an average life of 50,000 hours, over three times longer than a SON or Metal Halide lamp, significantly reducing maintenance costs. This product comes with a 3-year warranty for peace of mind. Please Note: If replacing SON/Metal Halide lamps, you will need to bypass the control gear and wire like a standard pendant fitting General Characteristics Wattage [W] 30 Voltage [V] AC96-AC265 Lumens [lm] 3900 Cap/Base ES/E27 Internal Fan No Lamp Diameter [mm] 85 Lamp Length [mm] 173 Colour temperature [K] 6000 Colour Rendering Index (CRI) [Ra] >70 Average Lamp Life [h] 50000 Working Temperature[°] 20-50 Beam Angle[°] 360 Working Frequency [Hz] 50-60 Equivalent MH/SON Wattage [W] 50 Wattage Reduction [%] 40
