• a reflector having at least one aperture for the attachment of a ballasted-socket assembly;
• said reflector having four hinged panels;
• each of the hinged panels being connected to a different edge of a common rectangular panel via a hinge;
• said reflector having a certain height immediately prior to being installed into the suspended ceiling;
• said certain height being substantially greater than the height of the reflector during shipment;
• a ballasted-socket assembly comprising:
• a power input connection, ballasting circuitry to properly power a gas-discharge lamp, a gas-discharge lamp socket, and an enclosure that contains and completely encloses:
• said ballasting circuitry, the connections to said gas-discharge lamp socket, and the interconnection between the output of said ballasting circuitry and said gas-discharge lamp socket;
• and
• a gas-discharge lamp.
