I love these lights. However, when I use my fire stick remote to turn down the volume of my sound bar, these lights turn on. In these instances, I have to be mindful to turn them off so that the batteries are not drained.My grandson wanted a sea themed decoration for his mommy's birthday and these fit the bill!These are truly beautiful lights with real stones this is my second set now ! I’m returning the first set because they didn’t stay lit even with new batteries in them they did not stay lit for more than three days.I just received another set I put brand new batteries in this set and I am not exaggerating they stayed lit for exactly 2 minutes and now they will not light again no matter how many times I change the batteries they’re just not working I don’t understand what’s going on I really would like the seller to explain to me what could possibly be wrongLight is more cool white than warm white and it’s so bright it’s hard to tell they’re crystals.I absolutely love these lights. The stones on the blue strand are actually a blueish-green "beach glass" color. The stones are also all different shapes and colors, so they're obviously not man-made. The bulbs inside the stones are a light blue, which is what shows when they're lit. When you select the light pattern you want, the lights will come on at that same time every day, and stay on for several hours. I really haven't timed them to see exactly when they go off. I've also had these for several months, and I still haven't had to replace the batteries.Quality lights, they are perfect for what I bought them for. Cant wait to try them at night, they were plenty bright in daylight. love the labeled settings and very high quality battery box. Would buy from this seller again.How charming and beautiful. I put them around my tub. No candles needed. It lights up the room with a beautiful blue ambiance. Even my husband likes them. No smoke from a blown out candle - these are perfect and little girls love these pretty things.....yay!!
