What Are a Lighting Designer's Objectives?

A lighting designer has four major objectives:

  1. Provide the visibility required based on the task to be performed and the economic objectives.
  2. Furnish high quality lighting by providing a uniform illuminance level and by minimizing the negative effects of direct and reflected glare.
  3. Choose luminaires aesthetically complimentary to the installation with mechanical, electrical and maintenance characteristics designed to minimize operational expense.
  4. Minimize energy usage while achieving the visibility, quality and aesthetic objectives.
