With a built-in microchip, the LED Ball Bulb will always work in harmony with other LED Ball Bulbs, making controller circuits unnecessary. With features such as low energy requirements and low heat production, the LED Ball Bulb has a life span of over 80,000 hours. Built-in effects include seven colors that gradually change, flash, chase, and flow, with the option of customizing upon customer request. Because each LED Ball Bulb consists of a programmed microchip, they are widely used to decorate buildings, plazas, advertisement boards, etc. to create special effects which would otherwise be non-existent.
