ANSI/IES RP-1-12 provides Table B1 for recommended maintained illuminance targets for the horizontal plane. Table B1h recommends a target value of 100 lux for casual dining and 200 lux for fast food dining.

The Dining Services Ergonomic Design Guidelines recommends lighting levels between 70 and 100 foot candles in warewashing areas for the safety and wellbeing of foodservice employees.

ANSI/IES RP-1-12 provides Table B1 for recommended maintained illuminance targets for the horizontal plane. Table B1h recommends a target value of 150 lux for cafeterias.

The Ontario Ministry of Labour's "Computer Ergonomics: Workstation Layout and Lighting" provides a checklist for computer workstations, which includes checking that light levels fall within 300-500 lux, and also that task lights are provided if required.

Adequate light levels are needed for a broad variety of activities, including reading various qualities and types of print, and working on detail-oriented tasks. Brightness levels also contribute to the perception of spaciousness, as well as to the overall visual appeal of illuminated spaces. Targeted task lighting can provide the necessary amount of light at workspaces without over-illuminating ancillary spaces; ambient light levels of 300 lux are sufficient for most tasks. Pairing adjustable direct task lighting with indirect or diffuse ambient lighting allows user customization and good visual acuity while providing more suitable background light. Light intensity for visual acuity is measured in lux (or foot candles), which is a measure of the way the eye responds to light weighted to the response of the cone cells—the main photoreceptors for daytime vision, located on the retina of the human eye.
