Since I work overtime late, I installed it because I can not see anything because it is pitch black when locking, but the capacity lasted longer with a decky battery? bright! I chose it, but I was very satisfied with the brightness. (Actual battery holding time is still unknown)
Installation was easier than I thought. Adjustment of sensing range and so on can be done easily. 3W kLED is bright and you can expect expectation for crime prevention. The price was also cheap compared with products with equivalent performance in the neighborhood home center and I'm very satisfied. It is recommended.
