Used lamps were still in service which only give off 2/3 to 1/4 of the illumination produced by new lamps. Rockface reflectance averages only 9-22% and therefore miners use their lamps set for narrow beam illumination, in order to obtain high enough luminances. However, this also produces luminance

✦ Synopsis
To provide readers of Applied Ergonomics with a selection of current ergonomics literature likely to be of direct practical value, abstracts are published selected from the collection held at the Ergonomics Information Analysis Centre. These abstracts are classified in a similar manner to the main articles in the journal; for easy reference, the code number at the head of each abstract (e g, 1.1.21) consists of the volume number, part or issue number and a sequential abstract number.
The published abstracts are only a selection of the Centre's material and readers concerned with specific areas are invited to contact the Centre for further information. Those readers unable to obtain copies of the original articles abstracted here through their usual sources, such as company librarian, may obtain photocopies from the Centre.
