Abstract
A reflector lamp has a glass reflector body and a separate neck body which mates with the reflector body. A light-source capsule is insertable into a bore of the reflector body from its base end. A positioning member holds the light-source capsule and is clamped between the neck and reflector bodies to secure the light-source capsule in the reflector body. The reflector and neck bodies have surfaces which cooperate with the positioning member to position the light source capsule at the focus of the reflector when the reflector body, capsule and positioning member, and neck body are stacked together.
