In-Depth Look at Photometric Reports

Understanding Luminous Flux

Luminous flux, measured in lumens, is the cornerstone of lighting design. For example, a residential living room might require fixtures with a total of 1,500-3,000 lumens, whereas an industrial warehouse may need 10,000 lumens per fixture for adequate illumination. Understanding lumens helps in selecting fixtures that are both efficient and suitable for the intended space.

Deciphering Spatial Light Distribution

Candela distribution plots can be daunting, but they're essential for visualizing how light emanates from a fixture. We'll walk you through interpreting these plots with examples, illustrating their implications in different settings like office spaces and corridors.

Assessing Illuminance Levels

Illuminance, measured in foot-candles, is crucial for task-specific lighting. For instance, a general office space might require 30-50 foot-candles, whereas more intricate tasks like drafting or sewing demand upwards of 100 foot-candles. We'll guide you in achieving the right balance for various applications.

Evaluating Color Characteristics

Color Rendering Index (CRI) and color temperature significantly affect how objects appear under artificial light. A high CRI is essential in spaces like art galleries where color accuracy is crucial. We'll show you how to choose lighting that enhances the ambiance of your space.
