The Vista Professional Outdoor Lighting LN16-5.5-W-15-LED MR-16 is a LED Lamp with 15 Degree Beam Spread that runs at 5.5W. Vista has developed a new LED lamp concept “from the ground up” that incorporates revolutionary patent-pending features that provide innovative performance advantages in outdoor environments. Outdoor applications have temperature and humidity extremes rarely encountered in indoors. Vista’s engineers tested hundreds of “indoor” lamps being offered to the landscape market and concluded that very few would offer the lifespan and long-term performance demanded by professionals. Vista’s new LED lamps will enable you to upgrade any existing landscape lighting installation to the energy-saving benefits of LED without sacrificing performance, longevity or quality of light.
