Interactive Lighting Concepts
Discover key lighting principles through sleek, interactive visualizations.
Illuminance and Lux
Illuminance measures the amount of light falling on a surface, expressed in lux (lumens per square meter). Adjust the number of lights and their brightness to see how they increase the illuminance on the table below, simulating a workspace.
Optimize Your Space
Aim for 300-500 lux for tasks like reading or working, adjusting light quantity and intensity.
Current Lux: 150
UGR (Unified Glare Rating)
UGR quantifies glare from light sources, affecting visual comfort. Move the light to see how its position relative to the viewer’s eyes changes glare levels—lower UGR means less discomfort.
Reduce Glare
Keep UGR below 19 for offices to ensure a comfortable environment.
Current UGR: 12.5
CRI (Colour Rendering Index)
CRI measures how accurately a light source renders colors compared to natural light (0-100). Adjust the slider to see how higher CRI values enhance colour vibrancy.
Better Colours
Aim for CRI above 80 for accurate colour representation in homes or retail.
Colour Temperature
Colour temperature (in Kelvin) defines the warmth or coolness of light. Lower values (e.g., 2700K) are warm and cozy, while higher values (e.g., 6500K) are cool and energizing. Adjust to see the effect.
Set the Mood
Use 2700-3000K for relaxation, 4000-6500K for focus.
