Certified Data Centre Professional (CDCP) Practice Exam

The minimum light level considered appropriate for service areas in a data center is 150 Lux. This level ensures that personnel can perform routine maintenance, equipment checks, and other operational tasks safely and efficiently. Adequate lighting is crucial for reducing the risk of accidents, such as trips and falls, and also for ensuring that technicians can see equipment clearly to monitor operations and troubleshoot issues effectively.

In data centers, service areas frequently require the use of technical diagnostic tools and reading of equipment displays, which necessitates sufficient illumination. A light level of 150 Lux strikes a balance between visibility and energy consumption, making it an established standard in environments where precision and safety are paramount.

Other light levels provided in the options, while potentially suitable for various applications, may not meet the specific requirements for adequate visibility and safety in data centers. Lower levels, like 100 Lux, may be insufficient for the detailed work technicians need to undertake, while higher levels, such as 200 or 250 Lux, could increase energy use without a significant benefit for the tasks performed in those areas.
