Tips

  • The big pad on the bottom side is a dead pad. No any circuit network on it.
  • Solder the positive wires as close as possible to both sides of the current sensing resistor.
  • 2 ears for mounting can be cut off if you don’t need it.
  • If the CAN wires are too long, bridge the “120R” jumper.

Quality metal enclosure. Look great. Two color levels. Charge even in indirect sunlight just fine. I have now bought 12 of these lights.

Very durable and designed to last a long time
Number of Items: 2
I've had a pair of these lights for 7-8 years and would still be using them with no issues if a naughty racoon hadn't taken an interest in them and broken the glass on one of them. I was delighted to find that the identical looking ones (operate slightly differently) were still available. They are extremely simple to put together (just screw together the durable metal pieces) and turn them on to the chosen brightness. It couldn't be much simpler. I also have other Gama Sonic solar lights and they are every bit as good.

Gama Sonic Solar Lights: Built to Last and Guaranteed
Number of Items: 2
These lights are nice and bright and stay on all night. I have other Gama Sonic solar lights also. One of them, which I didn't buy from Amazon, had a problem so I contacted Gama Sonic directly because they have a 2-year warranty. They responded immediately and I got it fixed and now I'm happy with it. I will keep buying their solar lights because they make good quality solar lights and have a 2-year warranty.

Very strong construction--no plastic
Number of Items: 2
Expensive, but appears to be very well made. The lights are made of aluminum, so the support is sturdier than the usual plastic. The poles are in two parts, so you have a choice of heights the light is above the surface. Battery replacements are expensive, but you should get two years or more from a battery. You have a choice of a quite bright white light or a less bright yellow light.
