Make a bold statement this holiday season with C9, transparent purple, Christmas light bulbs. Double-dipped with color for added depth, these intermediate base bulbs are fade resistant yet still let the incandescent filament shine. Using only 7 watts, the 130-volt bulb burns cooler and uses less energy. They even last longer to give you 3,000 hours of trouble free warm lighting. They are UL listed for indoor/outdoor use and come economically packed, 25 to a box. Let these colorful lights make your holiday lighting come alive.
