These are nice lights that give off good light, no shadows but bright enough to see if someone is standing near your home, and the sensor's work extremely well! Cars pass by my house and they pop on without any problems. I purchased 4 (2 were regular and 2 were 2x brighter)and they were installed into brick in about 45 minutes. They are worth purchasing if you do not want to pay for electrical wiring. The reason I gave it a 4 instead of a 5 is because they are slightly small in comparison to my house windows (1 story).

LOVE It, Works great and is easy to install
