A lamp, and a method of assembling the lamp, includes a heat sink, a heat conductive post extended longitudinally from the heat sink where the post has longitudinal faces that each has a longitudinally extending slot therein, a metal clad circuit board slid into each slot so that each circuit board is in thermal communication with the post where each circuit board has an exterior surface with an LED thereon, and a cap on top of the post where the cap abuts lateral end surfaces of the circuit boards. The cap may hold the circuit boards in their respective slots.

A lamp includes a transparent envelope having a first region defining an enclosed interior volume and a closure region adjacent to the first region, a light source in the interior volume and electrically coupled through the closure region, an interference filter coating on the exterior of the first region, and a light absorbing coating that is 7&#x2013;40 nanometers thick on the exterior of the first region, except in a ring-shaped portion adjacent to the closure region that has a thickness of 50&#x2013;200 nanometers.
