Question: Are these lights for 1 pillar? Would we need to order 4 for 4 pillars?
Document: I had several trees that i wanted to light up and these lights did a great job. I first bench tested the lights to see if any bulbs were out and found no bad bulbs. Ran them for about a month over Christmas and didn't loose any bulbs. They are now back in boxes and stored for next year. They are kind of expensive, but I am hoping they last me many seasons with no issues. The twinkle on the lights are very subtle, don't expect attention-grabbing, flashes of light.
I like them.
Answer: no
