The image here is showing a range of quality led high bay options for factory and warehouse. When considering factory and warehouse lighting upgrade, there are several important factors that need to be evaluated, light colour rendering index(CRI), brightness (light lux level), safety, glareness and energy consumption.
The lighting colour rendering index (CRI) will influence the quality assurance process in certain industries, such as food production, screen manufacturing and paint manufacturing etc. Higher CRI will have much truer colour of the object or product thus more reliable and more realistic review and testing results will be recorded or reported.
In regards to the brightness, it's really the essential goal of the lighting upgrade to increase the lux level at specific operating level (working bench height or ground level). According to several professional studies, lighting is influencing the worker's emotional aspects and thus varying the productivity. Higher brightness means higher lux level, which will enhance the efficiency of the whole working process.
There is no doubt that human resources are the most significant assets of the factory and company. However, the safety care for workers/employees have always been ignored. Actually, it's complicated to evaluate the light fitting’s safety of a factory and warehouse, to make things easier, these are some areas could be considered as the safety standard. The EMC Standard (radiation), Australia Electrical Safety Standard and light source cover for preventing components' dropping etc.
In addition to the light colour rendering index (CRI), brightness (light lux level) and safety, the glareness is another aspect the facilities manager or building manager should look into. For example, if the job requires a worker to look up and face to the direction of the light, a glare light will make their eyes sore and eventually results in some eye diseases. Then that would be a big problem for the worker himself/himself and the company.
Finally, another serious consideration for upgrading the existing lighting is to do with the energy reduction. For example, if the current light fitting installed is 400W metal halide, then a quality 200W LED high bay light should be able to meet the brightness requirements for that specific working task. The energy losses should also be taken into account. So, the existing energy consumption for an existing light fitting is 400W + 20% x400W = 480W. In this case, you will be saving (480W-200W)/480W = 58% on the energy consumption per fitting. In another word, this led lighting upgrade is actually bringing you a 58% saving on the electricity bill together with some other benefits from other aspects.
In conclusion, a lighting upgrade project for a factory or warehouse might be a difficult job if it's the first time you are doing it. Use the above summarized lighting guide as a reference might make your task easier and more logical. Lighting is an essential factor of a building especially for a production or work place, company will benefit from paying enough attentions to the lighting upgrade project.
