Question: What color is the light, is it the blue LED?
Document: I bought these lights about 2 years ago for our camping tent. I also use them under the umbrella that I put over the camp kitchen when we are cooking at night. The provide the perfect amount of light for me and I haven't had to change the batteries yet.
Put some batteries in. They work. Go back a few days later the light is dim. When you click the remote some lights go on, some don't. Same thing when you try to shut them off. Have put new batteries in several times,same thing. These are not worth it. I'm going to install electric lights. No more battery ones for me!
I bought a huge Moravian Star pendant candle holder that I plan to hang like a pendant light. I didn't want to have to climb up to light it. I bought these remote controlled puck lights to act as candles. They are bright enough to shine through dark amber glass. I would recommend this product because it functions very well.
The only thing that kept me from giving this 5 stars was the chunky convex design. The light is very thick and rounded in the middle so if you're using them underneath a cabinet, they may protrude a bit. The design needs to be slimmed down or possibly offered in different colors like grey or black to help them blend in. They work without the remote too (press center), which is great if you're kids or your animals misplace smaller items.
Answer: no
