light fixture
Let an agent explain light fixtures, relay types, components, standards and efficiency from lighting and electrical sources, describe the named forms and flag unverified aliases, route electrical safety, and distinguish fixtures from lamps or bulbs as the light source, lighting design and portable torches.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain light fixtures, relay types, components, standards and efficiency from lighting and electrical sources, describe the named forms and flag unverified aliases, route electrical safety, and distinguish fixtures from lamps or bulbs as the light source, lighting design and portable torches.
A device that holds one or more electric lamps and connects them to power, also called a luminaire or light fitting, ranging from portable lamps to ceiling fixtures, with forms the registry aliases name such as the gooseneck lamp with a flexible neck, church chandeliers, and marine bulkhead lanterns, while Lampette, fifo and lantern coche could not be clearly verified and should be reviewed; fixtures house lamps such as LED, fluorescent and incandescent sources and include reflectors, diffusers and control gear. Mains fixtures must meet electrical safety and, increasingly, energy efficiency rules, and installation of hard-wired fixtures should be done by qualified electricians.
What it is for: Holding and directing electric lighting.
It can be explain types and components; relay standards and efficiency; describe named forms; flag unverified aliases.
Distinguishing features
Holds lamps
Connects to power
Includes optics and gear
Regulated for safety
What it looks like
Ceiling, wall, floor and portable fittings holding bulbs, often with shades or diffusers.
Physical character
luminaire safety standard: IEC 60598 standard
EU incandescent phase-out: from 2009 note - progressive
registry parents: utensil, manufactured good note
How it is recognised
Device holding electric lamps
Lampette, gooseneck lamp, church chandelier, fifo, lantern bulkhead, lantern coche
A lamp or bulb is the light source; lighting design plans illumination; torches are handheld and battery-powered
