What Is a Commercial Lighting Survey?

A simple condition inventory is different from a lighting design assessment. Agree the scope before the visit: which areas are included, the measurements required and the proposals expected. Identify emergency lighting separately so the survey does not confuse normal illumination with the arrangements needed when normal lighting fails.

Identify fittings by area and record their type, condition, mounting position and controls. Note failed lamps, damaged equipment and fittings that are difficult to maintain. Keep photographs and measurements connected to their locations.

Record operating hours, switching arrangements and any use of presence or daylight controls. A fitting's rated power does not explain the energy used by a room without knowing how long it operates and how it is controlled.

HSE's workplace lighting guidance addresses lighting assessment in the workplace. Lighting needs to support the actual activities. Desk work, circulation, storage and detailed production tasks place different demands on the assessment. Include the people using the area when identifying glare, shadows and recurring difficulties.

Where measurements are included, record the position, conditions and method. Daylight, furniture layout and the operating state of the fittings affect the result. A single reading without context is a weak basis for a building-wide decision.

Separate immediate defects, maintenance tasks and design changes. A repair restores an existing fitting; an upgrade can change the layout, controls or type of equipment. Check compatibility, access and associated electrical work before treating new fittings as a direct replacement.

The proposal should explain the intended outcome and the checks needed after installation. Where savings are modelled, show the existing baseline, operating hours and assumptions. Describe them as estimates tied to those assumptions rather than established savings at the site.

Confirm access, working hours, protection of the area and any shutdown. Coordinate high-level work with the activities below it. Include removal of old equipment, reinstatement and information for the people who operate the new controls.

At completion, compare the installation with the agreed design and handover requirements. Keep updated layouts, product information and relevant test records with the building information.

No. The findings can support repairs, cleaning, control adjustments or a defined upgrade. The recommendation should follow the problem and evidence.

Include them explicitly in the survey scope. Their purpose and checks differ from normal lighting, even where equipment is physically combined.

Send layouts, operating hours, previous lighting work and a list of problem areas. Explain planned changes to the use of the space.
