A portable light bulb system includes a bulb that is removably coupled to a mounting bracket affixed to a support surface. The bulb includes an internal battery power supply and a LED light engine. A base of the bulb has a diameter sized to prevent the base from being inadvertently inserted into a conventional 110 volt electrical light bulb socket. The system also includes a wireless module communication device configured to wirelessly communicate with the bulb. In a first use position, operation of the bulb provides illumination to a region proximate the mounting bracket affixed to the support surface. An operator can disconnect the bulb from the bracket and bring the bulb to a second use position where operation of the bulb provides illumination to the second region. The operator can then return the bulb to the bracket at the first use position, or bring the bulb to yet another location for illumination.
