Quick answers to the questions we hear most from electricians, inspectors and facilities teams.

Emergency lighting testing verifies that your building's emergency lights provide adequate illumination during a power failure, enabling safe evacuation. BS 5266-1 requires monthly function tests and annual full-duration tests. Lux Meter Pro automates the timing, logging and certification so you stay compliant with minimal effort.
The lighting grid lets you map out a room and take lux readings at each grid point. The app calculates average, minimum and maximum illuminance across the space and generates a professional grid report. This is ideal for verifying uniformity in offices, warehouses, classrooms and retail spaces to BS EN 12464-1 standards.
Yes. You can upload your company logo, set your business name, address, accreditation details and contact information. All PDF certificates and reports are then branded with your details automatically, giving a professional finish for every job you complete.
