This Crompton Lamps 11W LED GLS light bulb with a ES-E27 Edison screw (27mm) fitting is a direct replacement for a traditional 75W light bulb, but has the potential to reduce your home lighting bills and reduce the frequency of needing to replace your light bulbs. LED technology is much more energy efficient than traditional light bulb technologies such as incandescent bulbs. This not only helps you save on your energy bills but also helps the environment too. Whereas a traditional light bulb would use 75W to produce 1055lm, this LED version uses just 11W equating to an energy-efficiency of 96lm/W. This high-performance LED light bulb sports a lightweight thermal plastic shell that is specifically designed to dissipate heat very effectively. This reduces the light bulb's running temperature and places less strain on its components resulting in a longer life span. With a long life of 15,000-hours, this LED GLS light bulb boasts an incredible 8.2-year lifespan if used for 5-hours a day. These light bulbs don’t need to be replaced as often which results in less money spent on replacement bulbs, and less time spent replacing them, too. Combine this superior longevity, negligible maintenance and replacement costs with the LED light bulb’s notable energy efficiency then the savings gleaned from each light bulb has the potential to reduce your lighting costs by up to 85%. Daylight (6500K) bulbs replicate the natural light seen on an overcast day. This colour can be used for areas where accurate colour reproduction is required, such as task lighting, retail display and workplaces and displays colours naturally as if they were outside. Unlike older other energy-saving technologies, LED bulbs light up instantly, with no waiting time to warm up to full brightness. This LED GLS light bulb will retrofit directly to any existing ES-E27 fixture; whether that be smaller domestic light fittings such as ceiling lights or floor lamps or up to large-scale commercial installations.
