Amy Clarke says in her InstaBrite review – “I bought four InstaBrite units but none of them work half the time. One of the units died a week later and does not switch on. The units randomly work for only a few hours and only one of the four works like it is meant to.”
Another user Alexa Snow says in her review – “The InstaBrite worked fine the first day but did nothing the next two nights. One of the units worked well but the second solar light flickered once and stopped working. It didn’t switch on even after pressing the On/Off button.”
Nicolas Sweeney complains in his review – “he InstaBrite cannot be turned off. So sundown time and the light turns on at about 1/2 brightness to unnecessarily illuminate an area and wasting the battery. It would have been better if the light actually stayed Off till it detected motion.”
One reviewer Derek mentions in his InstaBrite review –”I put the InstaBrite light inside the house but the unit needs direct sunlight to charge. I placed it outside and charged it for a day but it did not work for one night. The sensor malfunctioned at times.”
Another user Lara Smith says in her InstaBrite review – “I needed the light for an area outside the back door to let the dogs out early in the mornings and late at night. But though I placed it in full sun for more than a month it does not hold the charge for more than 4 hours. When it works, it lights up a large area.”
According to another reviewer Frank Tillman – “InstaBrite was great for seven months but then the motion sensor stopped registering anything. The light is installed outdoors but does not receive direct rain.”
Brianna Lopez says in her review – “The InstaBrite unit needs a sensitivity adjuster. There’s a distance of 31’ between the curb and where we have installed the light. But, the light is so sensitive that it glows every time a car passes in either direction. The battery drains by 8 PM. I accept that the light is bright and nice.”
Another InstaBrite customer Marcus Foley states in his review – “The InstaBrite light needs a really sunny day to provide it enough charge to last until 10 pm.”
One user Selena Case rues that – “There is no Off mode till motion is detected and the light keeps glowing dimly through the night.”
Shawn Maddox complains in his review – “The Instability light did not provide illumination like I expected. It isn’t very bright and only lasts for less than five hours. I wanted to use it on the camper door and bought it for the motion sensor feature. But I now use it as a night light for the kids. The battery dies before I go to bed after it charges all day in full sun.”
