OptiCore® LED Bulbs

Opticore® LED Christmas Bulbs

The story is simple. Christmas lighting enthusiasts wanted better C7 and C9 Christmas lights with better color, less hot spots, and more durability. They wanted LED bulbs that could withstand the weathering, be usable for multiple holiday seasons, and still look amazing. So Wintergreen Lighting created OptiCore LED bulbs using the latest SMD LED technology combined with a remarkable polycarbonate lens to make stunning C7 and C9 lights for Christmas, holidays, and events.
