Review on Transform Your Kitchen And More With MYPLUS LED Under Cabinet Lighting - 6 Piece Kit With 1260 Lumen, Warm White Glow And Easy Plug-In Installation by Stuart Sugden

So after having these for over a year now, I finally (by accident) figured out why they randomly turn on/off on their own. It's my cellphone! When I work with my cell phone on the desk where I have my light mounted, the light will turn off at random intervals. But, if I don't have my phone nearby, the light is rock solid. It fails especially if I am holding the phone in my hand, just underneath where it is mounted above my work desk and I am texting or browsing a website or taking a call. Could be this is your issue too. Otherwise, a good purchase.
