Abstract
An LED-based light can include a highly thermally conductive base having multiple radially outward projecting nodes. The nodes can be spaced apart in an axial and circumferential directions of the base. An electrical connector and at least one LED can be attached to the base, and a light transmitting bulb can be attached to the base and can cover the at least one LED. The geometry of the base can promote heat dissipation, which can allow the at least one LED to use enough power to produce an amount of luminosity that allows the LED-based light to replicate, for example, an incandescent light without overheating.
