Received on April 23, 2014. Installed at 01:05:14. Every day about 3 hours as garden lights in operation. Defective On May 22, 14 !!! Ie., A service life of only 63 hours at normal ambient temperatures. Coincidence? Material error? Or is the built-in electronics in the lamp too vulnerable? I have specially chosen a proprietary brand .... Therefore, unfortunately, only one star (for the first time in my reviews)
