This Crompton Lamps 5W dimmable LED golfball light bulb with a BC-B22d bayonet (22mm) fitting is a direct replacement for a traditional 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 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 40W to produce 470lm, this LED version uses just 5W equating to an energy-efficiency of 94lm/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 golfball 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. This dimmable lamp features DuoDim™ Technology making it compatible with most leading and trailing edge dimmers. 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. This LED golfball light bulb is a small round light bulb that will retrofit directly to any existing BC-B22d fixture; whether that be smaller domestic light fittings such as bedside lamps or fixtures with limited space or up to large-scale commercial installations.
