AR111 lamps are kick ass. They are a niche product, generally speaking, but if you need a high quality beam from long throws at relatively low wattage, AR111's are the lamp of choice for many designers. An LED version of the lamp with reliable color would be excellent. Unfortunately this report didn't have much good to say.Â
Given their overall performance characteristics, most—if not all—of the Series 17 LED AR111 lamps are unlikely to be effective replacements for halogen AR111 or PAR36 lamps. This is mostly a result of color quality and luminous intensity distribution characteristics. In some applications, they may perform acceptably—and could provide some energy savings—but continued improvement in this market category is warranted.
