Factory Lighting - specs and measurement ? | 6 June, 2002

Hi Mates,

Here's another boggle question :

does anyone know how to measure the work environment "Factory Lighting"?

what is the measuring equipment to use?

what is the specifications-range to measure factory Lighting?

Thanks for your help.

This might be a good place to start...I'll let you read it and tell us how helpful it was. ;)

You need an illuminance meter. We used these on the set of the Spice Girl videos. Search Yahoo for dozens of manufacturers.

Use OSHA specs for setting up your factory - but aren't you in China? Not sure if they have an OSHA over there.

He's not in China. He wears a kilt. They wear those in Scotland.

In that case, one 40 watt bulb should do. Hung very high from the roof and no shine on the floor.

If I remember correctly the standard we used was something like 350 candlepower at the work surface, and it can be measured with a standard photographic lightmeter

Hi mates,

thanks for the input from everyone, that standard shared with us (courtesy from Steve Thomas), ties in with what the majority have to say. Cheers!

350 candlepower is fairly low for high detail work. I spent some time in the construction industry laying out electrical blueprints for schools, and such. It was desirable to have more in the order of 700 fc for the desk surface that kids would work at. I would think that is more the ballpark to shoot for and seems to be held up by that link posted earlier in the thread. Unless you provide every workstation with a good magnifying lamp.

J-STD-001 guideline of 1000 lm/m^2 [93 fc] seems high, but it is the minimum level of illumination that operators and inspectors should have to perform their tasks.

IESNA LPD Architectural Recommendations Type of Facility||General Area percent / fc / type||Task Area percent / fc / type||Weighted Avg. Footcandles Classroom||35%/30 fc||65%/50 fc||43 Manufacturing||35 %/35 fc/Metal Halide||65 %/75 fc/Metal Halide||61 Manufacturing - Detail||80 %/75 fc/Metal Halide||20 %/300 fc/Metal Halide||120

I think I had my units wrong in my previous post - that blueprint job was 6 years ago and fading fast. My level of 700 would have the same units as Dave's level of 1000. This is the metric measurement of lux, vs the imperial footcandles. fc to lux is fc*10.76. 1000 lux is not out of line for inspectors. This gives good definition for the items under inspection. Most people would feel a little uncomfortable working under those conditions in all the tasks they do, so this brightness is not needed in all areas of the plant, and is expensive to achieve.

The 350 level mentioned is adequate, or on the high side of the recommended level for computer work.

That link posted previously is a very good document with a lot of information in it.
