1. Please confirm the voltage first. If the voltage of a product is 12V-24V, then you must use a professional LED voltage converter. 2. Please check the specifications of the product carefully before ordering to insure a proper fit. 3. Do not disassemble any bulbs by yourself. 4. Be sure to cut the power off before beginning installation to avoid personal injury.
Good quality product, nice light colour : warm white, for an LED Corn Bulb. With 100lmn per Watt this is a good investment ! Some versions like the E27 4W 108x3528SMD 648LM 2800-3000K Warm White Light LED Corn Bulb (220V) provides the same quality light and brightness for less consumption than this one. Still a very nice looking recommendation.
