C9 style bulbs bring back the traditional C9 look with the durability and cost savings of LED lighting. The lens is made from plastic for long life. The SMD LED is brighter than traditional 5-LED bulbs but uses less energy.
One year old LED Xmas light bulbs failed to work the second year I placed them on the house. Bulbs were replaced for free by the LED Warehouse, LLC. Thank you very much for backing up you product.
