Guides
Lighting survey guides.
These guides cover how to take the readings and how to record them so someone else can check them. They apply whatever you record the survey with, including Luxwork, our lighting survey app.
The guides
- What is an illuminance survey? What a lux level or light level survey measures, what the law asks for, when you need one, what the report contains, and who can do it.
- HSG38 lighting levels, and how to measure against them HSE's table of average and minimum lux for five kinds of work, and what the two columns mean.
- Lux levels by area HSE's figures for offices, warehouses, corridors, stairs, kitchens, loading bays and car parks, and when a higher figure applies.
- How to do a lux survey The method in the order you do it: the figure you're measuring against, the instrument, conditions, the plane, the grid, and what to record.
- Emergency lighting lux levels: how to check them What the emergency lighting code covers, how to take readings with the normal supply off, what to record, and why a lux check isn't the duration test.
- What a lighting survey report should contain The list a report needs so someone else can check it, shown on a specimen report, with questions to ask of any survey you receive.
- Are lux meter apps accurate enough for a lighting survey? What a phone app measures, what independent tests found, and what a survey needs from its instrument instead.
