Yes. Lux Meter Pro generates legally compliant PDF certificates for emergency lighting tests, workplace assessments, and minor electrical works.These include all required data, timestamps, and GPS coordinates for audit trails.
Lumens measure total light output from a source, while lux measures illuminance - how much light reaches a surface.1 lux = 1 lumen per square metre. Lux matters for compliance as it measures the light people experience.
BS 5266-1 requires daily visual checks, monthly function tests (30 seconds), and annual duration tests (full battery discharge).Our app automates scheduling and documentation for all required tests.
For professional use, calibration should be checked annually against certified reference equipment. Lux Meter Pro includes calibration features and allows custom correction factors based on your reference equipment.
