Review on [6-Pack] 7ft Starry String Lights, Fairy String Lights with 20 Micro LEDs on Copper Wire. Includes 2pcs CR2032 Batteries. Ideal for Wedding Centerpieces, Parties, Christmas, Table Decorations in Warm White. by Rick Booth

Very satisfied so far. They give off a yellow white light which is exactly what I was looking for in an outdoor dining room. I bought these to use in an old outdoor chandelier. They're easy to change if you want. I cut off the coin's battery compartment and soldered three bulbs in series with a 9 volt battery for power. Now I can turn on the two switches on the outside of the Mason jars and turn on all six lights, and it's also easier to change batteries without tiny screws. I'll update this once I see battery life with 9v batteries. UPDATE SEPTEMBER 09, 2019: As detailed above with the 9v mod, they become strong after five parties where we leave the lights on for 4-5 hours at a time. Time. So far it's very durable (the chandelier is always outside under a canopy) and guests always ask about the lighting.
