I purchased one of these PAR38 LED flood lights back in April of 2011 to test it out in my back yard. It worked great, and I purchased two more to install out front over my driveway. Those two lights out front are like mini-suns, and light up my whole driveway, as well as part of the adjacent yard. I live on a pretty dark street, and those lights can be seen all the way down the block. What is so great is that they provide as much light as two standard 90-watt PAR38 halogen flood lights, while only consuming 32 watts of power, combined. That is an 83% power savings. The lights also burn much cooler than the halogen lights, so they will last much longer. I expect to recover the money I paid for the bulbs from power savings within about 2-years, and they will continue to deliver savings for several more years after that. I intend to soon replace four other exterior halogen spotlights with the PAR38 LED flood lights, in my quest to change all of the lights in my house (those used more than 2-3 hours per day) to LED lighting. Overall, this is a very solid product, and I highly recommend it.
