Accent Lighting
Used to highlight design features, artwork, or specific architectural elements.
Ambient Lighting
General illumination that provides overall visibility and creates the foundation for lighting a space.
Beam Angle
The angle at which light is emitted from a fixture, affecting the spread of illumination.
Color Temperature
Measured in Kelvins (K), it describes the warmth or coolness of light emitted by a bulb.
CRI (Color Rendering Index)
A scale from 0 to 100 that rates a light source's ability to reveal colors accurately.
Diffuser
A translucent piece of glass or plastic sheet which shields the light source in a fixture. The light transmitted throughout the diffuser will be redirected and scattered.
Dimmable Lighting
Lighting systems or bulbs that allow brightness adjustment to suit preferences or energy-saving needs.
Downlighting
A lighting technique where fixtures are directed downward to focus light on specific areas, often used for task lighting.
Efficacy
A measure of how efficiently a light source converts energy into light, expressed in lumens per watt (lm/W).
Energy Star
Certification for energy-efficient lighting products that meet strict energy performance standards.
Glare
Uncomfortable brightness caused by excessive light or poorly positioned fixtures.
IP Rating (Ingress Protection)
A standard indicating the level of protection a light fixture has against dust and water. Example IP65 for outdoor use.
Kelvin (K)
A unit of measurement for the color temperature of light. Lower values (e.g., 2700K) are warm, while higher values (e.g., 5000K) are cool.
LED Driver
A device that regulates power to an LED light source, ensuring consistent performance.
Lifespan
The estimated operational life of a lighting product, often stated in hours.
Lumen
A measure of the total visible light emitted by a source. Higher lumens mean brighter light.
Lux
A unit of illuminance, measuring the amount of light that hits a surface.
Photometric Data
Information that describes a lighting fixture’s performance, including beam spread, lux levels, and efficiency.
Retrofit Lighting
Upgrading or replacing existing light fixtures with modern, energy-efficient alternatives.
RGB Lighting
Fixtures that use red, green, and blue LEDs to produce a spectrum of colors for decorative and dynamic effects.
Smart Lighting
Lighting systems that can be controlled through apps, sensors, or automation, offering advanced features like scheduling and dimming.
Task Lighting
Lighting focused on specific areas to assist with activities like reading, cooking, or working.
Tunable White
Lighting technology that allows color temperature adjustments between warm and cool light to suit different moods or tasks.
Uniformity Ratio
A measure of how evenly light is distributed across a space.
Uplighting
Lighting directed upwards to highlight ceilings, walls, or architectural features.
Warm Dim Technology
Advanced LED technology that mimics the dimming effect of incandescent lights by becoming warmer as brightness decreases.
