1. Overview

LED explosion-proof lamps are known for their brightness, but sometimes they can be too glaring. Why does this happen, and how can it be improved? Traditionally, glare is reduced by optimizing light distribution or lowering luminous flux. However, an often-overlooked factor is the choice of color temperature. Selecting the right color temperature can significantly impact the overall lighting experience and reduce discomfort in work environments.

2. Technical Indicators

Color temperature is a critical parameter in determining the visual effect of lighting. The bluer the light, the higher the color temperature, while warmer tones have lower values. For example, color temperatures below 3300K create a warm, cozy feel, while those between 3000K and 5000K offer a balanced, refreshing look. Above 5000K, the light becomes cooler, brighter, and more likely to cause glare.

In industrial settings where LED explosion-proof lamps are commonly used, it's advisable to avoid high color temperatures. A middle range of 4000–5000K is typically recommended. This range mimics natural daylight in the afternoon, providing comfortable illumination without causing eye strain or discomfort to workers. It also helps improve mood and productivity in the field.
