The pumpkins lights were a success. They have 4 LED's with a subtle flicker effect. They looked bright for 2 weeks at 6 hours a night. I changed most of the batteries a few days before Halloween so they would show up in photos. They would have made it 3 weeks only much dimmer.
The down side is they do take 3 AAA batteries. Even with recycling that is a lot of batteries used. I bought them in mega packs of 72 on Amazon. Most of the lights came from Amazon. Tried to pay $4 each only as Halloween got closer the price kept going up. The light pucks come in a solid white case or orange. Both colors are the same lights and the white ones are cheaper at Halloween. They measure 3 3/4 inches. Search for Pumpkin Lights and they come up under multiple sellers on Amazon.
The lights worked well and looked good. Bright light for at least 2 weeks. The pucks are being used year round in candle holders and lanterns. The remote control is the biggest selling point. Turning 20 lights on and off instantly is such a time saver. The lights are not water proof. A ZipLoc bag worked to keep them dry.
