Numbering System
Purpose
The purpose of the system is to provide an immediate and positive identification of a catalogue number in relation to range and description
of the lantern.
Basic Principle
1. All items of streetlighting equipment are catalogued with prefix Q. This automatically locates the whole range in the same section of the
Comprehensive Price List for easier location. It also gives an immediate statement of equipment type.
2. Second and third digits are initial letter and number of the lantern in the range description:
A3 = Alpha 3
B4 = Beta 4
G3 = Gamma 3 etc.
3. A standard vocabulary of suffix letters, indicative of type detail, with or without gear, accessories or attachments etc., are included as
appropiate with the catalogue number:
S = Semi-cut-off
V = Anti-vandal bowl
B = With gear
4. A system of four digit number indicating no. of lamps and maximum wattages.
5. Where components making up a lantern are supplied as separate packages, each package has a catalogue number:
Alpha 3 Canopy SCO with gear - QA3 B1400
Alpha 3 Gear Tray 400W Kolorlux 240V 50Hz - QA3 B1400.4
Alpha 3 Lampholder bracket for 250/400W SCO - QA3 SL
Alpha 3 bowl assembly 250/400W SCO - QA3 D
6. When producing a complete fitting catalogue number, separate packages are indciated by an oblique stroke /.
The complete lantern Alpha 3 SCO with 400W Kolorlux becomes: QA3/SL/D/B1400.4 - indicating four packages.
A further example would be:
QB4 U1200 = Open Beta 4 canopy with lug
B22 = 2 Pin BC lampholder
QB4 Y = Beta 4 refractor dome
The complete Beta 4 open lantern for GLS lamp then becomes QB4U/Y/1200B22 - indicating the entire package.
