Angle at which light is emitted from a lamp or fixture, affecting how spread out or focused the light is.

Unit of luminous intensity, measuring the intensity of light emitted in a specific direction.

Major improvements or additions to a property that increase its value, as opposed to routine maintenance.

Measure used in the income approach, calculating the ratio between the annual net income and the value of a property.

LED type utlizing lower power LED chips connected in series in parallel to eliminate the packaging of individual semiconductors. COB process reduces costs, weight and size. Chips can be mounted directly to lamp heat sinks, providing direct thermal dissipation. While not optimal for high intensity applications like street lights, COBs are ideal for filament style lamps.

Scale (0-100) that measures how accurately a light source displays colors in comparison to natural daylight.

Property used for business purposes, including office buildings, retail spaces, and industrial properties.

Smaller version of the standard fluorescent light, more energy-efficient than incandescent bulbs.
