Question by jeremiah: Will a magnifying glass in front of a solar panel increase the energy harnessed by the panel? I was just curious because if a solar panel was adequately cooled and more energy was produced maybe solar panels would become a more contender for cleaner energy. —————————————— Answer by N!ck > YouYa sort

Review: This lamp is good looking and easy to install, but I am not happy with the functioning of the sensor. It seems very sensitive straight on. It senses cars going by in the street about 50 feet away, but doesn’t sense me walking by the side, only 15 feet away. If I set it to high sensitivity to get nearby movements, the light goes on very frequently due to street activity. I plan to change lamps, since I want one that turns the light on when someone approaches the front door from the side where my driveway is, but doesn’t turn on every time a car goes by.

Review: I’ve only had this product installed for 3 weeks. It has a nice slick look, which will hopefully last much longer than our previous antique brass which tarnished in a few years. So far, it is working fine. I use it in the dusk to dawn mode, and really appreciate the test setting which allows me to verify my installation is correct and that new bulbs are working the one time I needed to replace one carried over from the old fixture. The base has very limited room to accomodate wiring and base plates that makes it impossible to install this unit on a flat surface. It needs to be installed over a recessed box that can hold the wiring and connections.

Review: I was having trouble finding motion sensing lights that weren’t obnoxiously large. These were the perfect size and, so far, they’re working well. They look good too. On the low sensitivity setting the light is tripped at about 30 feet. The high setting picks up passing cars (at 60+ feet).
