The disclosed invention relates to a bidirectional shelf assembly which may be used in a single door or double door cabinet. The cabinet may comprise the decontamination chamber of a decontamination unit. The cabinet may comprise a sterilizer and/or washer.

Shelf assembly

An apparatus is provided for a lighthead which allows the lamp to be serviced without removing any components of the lighthead. The invention includes a lamp socket connected to the handle of the lighthead. The handle can be displaced from an operative position to expose the lamp for maintenance while remaining attached to the lighthead to prevent damage or loss of the components.

Lamp change mechanism

A pattern change mechanism is provided for use with a lighting fixture. The mechanism includes a plurality of blocking members for blocking light directed by the reflector of the lighting fixture toward a target surface, means for moving the blocking members to achieve small, medium and large patterns of light on the target surface. The moving means includes a rotation member, drive means, actuator means linked to the blocking members and a handle for rotating the rotation member to thereby effect movement of the blocking members through the drive means and actuator means.
