Light is an essential part of our daily lives and plays a crucial role in many applications. In work lighting, it is not only important to have sufficient light but also to consider the properties of light that affect efficiency, safety, and comfort.

The Key Properties of Light

1. Light Output (Lumen)

Light output, expressed in lumens (lm), indicates how much visible light a light source emits. The higher the number of lumens, the brighter the light source. In work lighting, high light output is often necessary to clearly see details and work safely.

2. Light Color (Kelvin)

The color temperature of light, measured in Kelvin (K), determines whether the light feels warm (low Kelvin value) or cool (high Kelvin value). For work lighting, neutral white or cool white (4000K - 6000K) is often preferred, as it enhances concentration and reduces fatigue.

3. Light Distribution and Beam Angle

The way light is distributed is crucial for an efficient workspace. A narrow beam angle creates a focused light beam, ideal for precise tasks. A wider beam angle provides uniform illumination over a larger area.

4. Light Intensity and Contrast

A proper balance between light intensity and contrast reduces shadows and glare. Excessively bright light can cause discomfort, while insufficient lighting can lead to fatigue and reduced productivity.

5. Color Rendering Index (CRI)

The Color Rendering Index (CRI) indicates how accurately colors appear under a light source. A high CRI value (>80) is important for work lighting where color differentiation is essential, such as in industrial or medical environments.
