This string of lights has large bulbs made of plastic (dropped them a few times and they still work, oops!) that give off a nice soft light. The cord is VERY heavy and looks like it could withstand a lot of wear and tear. I wanted something to throw some light up into the high ceiling of my screened in porch and one string did the trick. Very well made set of lights. Had to add to this review! These lights were PERFECT for a COVID-19 Barn Prom!!!!
