Indoor Furnishings User Manual

The lamp industry strives continuously to meet customers’ needs.Its innovative power has led to a tremendous variety of different light
sources.To enable customers and experts to find their way within the diversity of products,a general system for the coding of lamps has
been developed (see IEC Publication 61231).
The code does not replace specific markings used by individual manufacturers on their lamps or in their catalogues,but is promoted for
cross-referencing purposes and,in due course,to replace national and regional lamp coding systems which already exist.
The object of the international lamp coding system is:
- to improve communication about the different types of lamps
- to help in discussions concerning interchangeability and compatibility of products;
- to create a closer relationship between international standards and manufacturers’ literature (the code is given on all lamp data sheets
in IEC 60901);
- to enable correct replacements of lamps;
- to be used as a complementary marking on the luminaire;
- to replace national and regional coding systems.
Below a short description is given of the structure of the ILCOS code for ‘TL’5 lamps.
Example:FDH-14/27/1B-L/P-G5-16/550
• FDH: Fluorescent lamp Double-capped for High-frequency operation only
• 14: wattage
• 27: colour temperature (divided by 100)
• 1B: colour rendering group according to CIE (R
a
= 80 - 90)
• L/P: starting details (starterless/pre-heated)
• G5: lamp cap
• 16/550: nominal lamp diameter/length in mm
