LED Reflector bulbs can significantly reduce your energy and maintenance costs in comparison to standard reflectors. Superior efficiency, longevity and versatility have all become hallmarks of LED technology and nowhere is this typified more than the new range of replacement LED Reflectors. Consuming approximately 90% less energy than incandescent versions, these LED spotlights can conceivably reduce your lighting bill by a similar amount. PAR bulbs get their name from the glass enclosure and a highly reflective aluminium coating (pressed aluminium reflector) and by the size of its diameter in 1/8th inch quantities. Available in PAR20, PAR30 and PAR38 sizes.
