Lights were received promptly and left for 2 days in the sun to charge. The lights have three operating modes but only one push button switch so it took some trial and error to work out which mode was correct. Luckily I haven’t yet erected the lights as this would have been most annoying post installation. May I suggest a 4-way switch - off and each of the three modes. When set in sensor modes the two lights I bought display a variation in sensitivity of about 2 metres, which in practice is ok.
Nice light! I got one to place above the garage door. It comes in handy to adjust the direction of the light as you need. Not sure exactly how long does it keep the charge, but came home after midnight few time and it is still worked. Good purchase
