Review on 🌟 15 Pack of SmilingTown Starry Fairy String Lights - Battery Powered LED Firefly Silver Wire Lights with 20 LEDs and 7.2FT Length. Ideal for DIY Wedding Party Jar Centerpiece, Christmas Decorations, and more. (Cool White) by Brenda Young

I wanted these because the battery pack is very thin and small and fits perfectly under the lid of a small jar. I used this removable sticky material to stick it to the bottom of the lid to keep it hidden. Then he unwound the light thread and put it in the wall jar. They are used on outdoor tables and shelves for parties. It's a little cooler than "Warm White" but not the sterile blue-white I hate. I would say they are in the 3000K range (Kelvin range). I would have liked even warmer (yellow) light, but these are still very good. You don't look very sterile. A tip: pull the plastic tab that separates the battery from the metal connector and turn them all on to see if they're broken. ONE out of 15 units didn't work for me. I tried all of the company's offers, but since they don't sell or ship individual devices, they refunded me $1.30 per device. Your customer service was great. Very attentive and fixed the problem. I have 14 units left, but that's okay. I didn't need that much anyway.
