LED downlights use about 85% less energy than halogen or incandescent light and approximately 30% less energy than CFL lights. By reducing your energy consumption, they save you money on your power bills! LED downlights have a long lifespan (between 30,000-50,000 hours depending on the type of LED product) and reach full brightness instantly. LED downlights are also safer than halogen because LED downlights run at a lower temperature and contain no mercury or lead. They emit no UV rays or infrared radiation and are environmentally friendly – cuts greenhouse gas emissions and reduces landfill.
