Really convenient light bulb that can be turned on and off automatically without you having to do it yourself. Will fit into most standard light bulb fistures such as E26 socket and has an equivalent brightness level equal to other LEDs if not, brighter. What is also great about it is that saves more energy compared to others thanks to its auto on/off mode. This definitely is its selling point since you you want light only when needed and not when you don't need it.
