Yep. These do get hotter than you'd think though. Even at 12volts they get pretty warm. Maybe because of the rubber covering/smothering them? I tested and they will run up to 17 volts or more, then they start blinking and shut off due to over volt. They will come back on though, which is a good thing.
I believe each 4 foot piece is 0.5 amps @ 12 volts. They would run forever on a large sized battery. And, they do run on a 10 - 15 watt solar panel. So in theory, you can run the wires from a solar panel into the house and run the LED's during the day or in a dark basement/room. (panic room?) etc.
Being LED, they do not Cast like a regular bulb, so lighting a room with them is difficult. (the other one below does a better job)
Various colors available too I think on amazon.
The other LED Light that works great is:

I've got one on the mobility scooter and one for the emergency kit/camper. Worked great with a nearly dead battery in the camper. .4 amps, runs on voltage from 7 beyond 12. I test them on a variable power supply and mark them with the amp rating for future reference in the field.![]()
