About a month ago I was found these two wireless LED puck lights with remote. We have a travel trailer and go to parks that do not have electricity on occasion and wanted to have some battery lights. These two puck lights are bright enough to light up our most the area we wanted lite up. What is nice is they can be mounted with screws to be permanent or with adhesive tape and moved around. Also, they take only 3 AA batteries and last over 100 hours of use. Another thing I like is that I can use the remote and set the timer to turn the lights off in increments of 15, 30, 60 or 120 minutes. This comes in handy when we take the little ones with us. We can dim the brightness and use it like a nightlight and then have it go off at a specific time. No more climbing out of bed to turn off the light or running the generator to power the lights. I will be buying another set of these for home use too.
