lighting
Let an agent explain lighting and its applications, relay design principles, standards and technologies from lighting engineering sources, describe specialised systems such as approach lighting, and distinguish lighting from light sources and from lighting in photography and film.
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 lighting and its applications, relay design principles, standards and technologies from lighting engineering sources, describe specialised systems such as approach lighting, and distinguish lighting from light sources and from lighting in photography and film.
The deliberate use of light to illuminate spaces, objects and routes, whether by daylight or artificial sources, for visibility, safety, work and effect, in applications from interior and architectural lighting to street lighting, bicycle and vehicle lighting, aircraft lights and airport approach lighting systems, mobile light towers for sites and events, stage lighting, and solar garden lights; lighting design balances quantity, quality, colour, glare and energy use, and is regulated for safety and efficiency.
What it is for: Illuminating for visibility, safety and effect.
It can be explain applications and principles; relay standards and technologies; describe specialised systems; distinguish related senses.
Distinguishing features
Illuminance and quality
Energy use
Safety function
Diverse applications
What it looks like
Not a visible object; lamps, luminaires and lit environments.
Physical character
share of global electricity for lighting: about 15 percent - IEA estimates, falling with LEDs
office illuminance: about 500 lux - EN 12464 typical
LED efficacy: over 150 lm/W - best products
How it is recognised
Deliberate illumination
Interior, street, bicycle, aircraft and approach lighting, light towers, solar garden lights
A light source is the lamp; lighting in film and photography is a specialised craft

What the second pass must settle
- Should street lighting and approach lighting system be separate primary entries?
- How should lighting standards be linked?
- The registry entry has merged aliases naming specialised systems and products; should they be split off?
