About this product
This Crompton Lamps 4W LED GLS light bulb with a ES-E27 Edison screw (27mm) cap is a retrofit replacement for a incandescent 40W 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 has superior energy efficiency than traditional incandescent or halogen light bulbs which helps you save on your energy bills and helps the environment too.Whereas a traditional light bulb would use 40W to produce 470lm, this LED version uses just 4W equating to an excellent energy-efficiency of 118lm/W.This high-performance LED light bulb sports a thermal plastic body that is specifically designed to dissipate heat 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 dont need to be replaced as often which results in less money spent on replacement bulbs, less time spent replacing them, and less old light bulbs going to landfill too.Combine this superior longevity, negligible maintenance and replacement costs with the LED light bulbs notable energy efficiency; then the savings from each light bulb has the potential to reduce your lighting costs by up to 90%.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.
