A light guide () for a lamp includes a proximal end () configured to receive light from at least one LED. The received light forms an internal beam inside the light guide. The light guide angularly redistributes the LED light to have a specified angular output distribution. The light guide includes a distal end () having a peripheral portion (). The light guide has a longitudinal axis (A) extending from the proximal end to the distal end. The light guide includes a lateral side () extending from the proximal end () to the peripheral portion () of the distal end (). In a cross-section that includes the longitudinal axis, the lateral side of the light guide includes both a convex region and a concave region.
