I purchased this outdoor wall motion sensor light with a high efficiency lens by #Neporal for the outside corner of my home. Seems my older one went out after several months of use that was hard wired in. I went to buy a bulb and it was so expensive to replace and a new hardwired one would be too much work for my son to do. I decided to go with this option as #1 it was easy to install. #2- it wouldn't add anything to my electric bill since it runs on solar power and #3- it asthetically looked very nice along the lines of my home. After sitting in the sun most of the day I put it to the test. I went out near the light and wham.. it came on . I love the brightness of this light...Much brighter than my old hardwired light. I also love that this is waterproof. It definitely lit up the back corner of my home and for only $15.99 without adding any additional cost to my electric bill. At this price I'm going to be buying a few more for the garage door, and the carport since my carport has alight that's extremely hard to reach to change the lightbulb . At this price you're really going to want to buy several for around the outside of the home.
