FlexFilament LED shatterproof string lights from Wintergreen Lighting combine everything you want in elegant Christmas lights. The visible curved filament is lined with LED diodes that produce a warm, natural light that looks just like the old-fashioned Christmas lights of days gone by. Yet because they are LED, they use only 0.8 watts per bulb, making them far more energy efficient than traditional C7 bulbs. And their PolyFlex PET lenses are lightweight yet shatterproof, so you don’t have to worry about breakage during setup, takedown, or during rough weather. These Edison string lights are an investment in your Christmas that will pay dividends for years to come.
