Imagine that you need a yard light, maybe for the driveway, maybe for your campsite, maybe in a corral or maybe at the cabin. Well, the first thing you need to do is contact an electrician to see how much is it going to cost to get power to your desired location. Well a few hundred dollars later you can now buy a regular sodium yard light and start paying power bills.
Now you can simply put a ladder up and mount your light. No wires to run, no power bills to pay. Turn it on and off using the supplied remote control or set it for any of the 5 pre-programmed functions.
