I recently installed a 100W LED bulb in my backyard porch light. Last night I came home and was pretty confused because I thought that it was daylight in my backyard and dark in my front yard. The light bulb puts off such a bright natural light that it will confuse you at first glance as to whether its natural or not. The shadows cast are the same as during the day the colors are the same. I've used LED bulbs in other parts of my house but none that were as powerful and just the sheer power of that bulb and the brightness it displays is incredible. So my light experience yesterday was one of natural light confusion rather than straight natural light.
