Litetronics LED PARFECTION series light bulbs save up to 85 percent on energy costs, and they are RoHS compliant with mercury-free and leadfree construction, making them the greenest replacement for halogen lighting. Their elegant style maintains the look and shape of an ordinary halogen PAR bulb, and they have the ability to throw a crisp, white beam of light to illuminate brilliant merchandise displays just like halogen bulbs. LED PARFECTION bulbs use a patent pending Eco-Clear optics lens that generates high center beam candle power. Unlike halogen, LED PARFECTION bulbs do not generate ultraviolet, infrared light, or as much heat. This protects displayed items from fading colors and spoiling perishable items that are sensitive to heat.
