LED PAR lamps dominate the ENERGY STAR qualified product list, so back in 2012 IEE to develop recommendations for top performing PAR38 and PAR30 LED lamps. The team developed an evaluation protocol that starts with the lamps found in ENERGY STAR's list, to which we applied product criteria screens and testing to a subset of lamps to determine the 10 top performers. Efficiency along with aesthetics, payback period, and dimming performance were key criteria to the ranking.
LED lighting products compete with traditional lighting technologies on the basis of the numerous benefits of LED lighting relative to such technology including greater energy efficiency, longer lifetime, improved durability, increased environmental friendliness, digital controllability, smaller size, directionality and lower heat output.
LED lighting products face competition in the general lighting market from both traditional lighting technologies provided by numerous vendors and from LED lighting products provided by a growing roster of industry specialized participants.
