The MINIMUM recommended lighting requirement in a telecommunications room (TR) at the point of cable terminations is:

150 lux is far below the minimum required for detailed termination work and does not meet the standard specified for TR cable termination points.

300 lux falls short of the 500 lux minimum required at termination points and would not provide adequate visibility for precise cabling tasks.

BICSI TDMM and ANSI/TIA-569 specify a minimum of 500 lux measured at the point of cable terminations within a TR, reflecting the visual precision required for reading color codes and small labels. This measurement applies at the actual work surface or termination panel, not just the general room average. Adequate lighting at this level directly reduces installation errors and supports safe ongoing maintenance.

750 lux exceeds the specified minimum; while higher illumination is permissible, it is not the minimum threshold defined by the standard.

1000 lux significantly exceeds the minimum requirement and is more representative of surgical or precision manufacturing environments, not the TR lighting standard.
