Eco-Par Reflector Halogen light bulbs are an excellent energy-saving alternative to popular compact fluorescent light bulbs and expensive LED light bulbs. These light bulbs provide all the benefits of halogen lighting while offering superior light quality and reduced wattage. Energy savings range from 16%-24% versus standard PAR light bulbs with similar light output.
