6.5′ Dunhill Fir Christmas Tree 600 Dual Color LED Lights National Tree Company. This fantastically festive tree is strung with 600 Dual Color LED lights prior to packaging and includes a sturdy, metal base for a more convenient setup. The Dual Color LED bulbs can alternate between white and multicolor lights and includes a switch to control ten different light functions, allowing the bulbs to twinkle, flash or fade on either color setting. The lights operate individually, so if the bulb lens has not been cracked or broken, the light set will continue to illuminate except for any individual bulbs that are not working. This tree also includes PowerConnect, an additional feature where the wires run through the middle pole of the tree, eliminating the need for extension cords and plugs in the branches.
