Embodiments of a lamp that distributes light from one or more light emitting diode (LED) devices with an intensity distribution having a batwing appearance. These embodiments can comprise a lens having a lens body with different types of optics to achieve the preferred distribution. In one example, the lens body has a first section with optics that embody a plurality of prismatic facets and a second section with optics that form a convex shape, curving outward relative to the LED device.
