The importance of lighting to work productivity is unknown to many people or just neglected even if they know how important workplace lighting becomes. In modern offices or workshops, the proper workplace lighting fixtures are described to be one of the most important factor leading to the improvement or decrease of employees' work performance. There 're some common factors of lighting that get involved in affecting work productivity including light levels (dim or sharp, for example), color temperatures , as well as lighting quality itself.
Use the proper workplace light level
The right light level at workplace is one of key element measuring whether lighting design in workspace is successful or not. If lighting is dim, it easily leads to daytime sleepiness and reduced motivation from employees, which is detrimental to work productivity. Some studies conducted by professional lighting associations also state that dim lighting can cause eye strain and headaches to workers. In contrast, the space with much too sharp lighting is also not the good lighting idea as workers will find it difficult to focus on work and even have sense of discomfort and anxiety under harsh lighting environments.
Choose the right color temperatures
The color temperature of light source is one of significant factor to be considered for workplace lighting design as it can directly influence our eyesight as well as physical and mental well-being. There're three types of color temperatures which include Warm Light(2700K-3000K),Cool White(3000k-5000K), Daylight colors from 5000K-6500K. The higher the color temperatures, the more blue the light will be. In workplace where people need to stay focused and motivated, the lighting source of warm color temperature is apparently not the good choice. People working under the warm lighting atmosphere tend to doze and fall asleep. Comparably, a workplace with crisp, clean and dynamic lighting makes workers feel invigorated and excited, helpful to improve work productivity. In general, the proper range of color temperature for workplace illumination is 3300-5300K according to specific workplace illumination requirements and standards.
The lighting quality itself matters
As employees are exposed to illumination in workplace for a long periods of time, the quality of lighting can influence how they work to a certain extent. Some common factors that's taken into consideration for selection of light fixtures include lighting uniformity, color rendering index, glare control capability or UGR level, heat dissipation performance, lighting safety, eco-friendliness ,etc. The light fittings of low quality come with bad experience of lighting use and short lifespan, as well as potential harm to people. For example, the lighting with high glare & flicker and UV radiation not only causes discomfort and anxiety but also pose potential health threats to workers.
