Company Profile
Terminology & Definitions: Welded Leads for Lighting
Terminology of Lamp Leads Length Measurement Criteria
The Inner Section
Some of the standard materials used are: Copper, Nickel, Nickel-Plated Steel & Nickel-Plated Copper. Temper is soft, half-hard or hard depending on the application.
The length is measured from the end of the press section to the end of the inner section. It includes the weld knot at the end of the press section.
The Press Section
By far the most common material is Dumet wire: Tungsten, Molybdenum and Nickel-Iron alloy wire are also used.
The length excludes the weld knots.
The Outer Section
Metals for this portion may be Monel, Nickel D, Copper, Copper-Plated Steel.
The length is measured from the end of the press section to the end of the outer section.
Four-Part Leads
Sections adjacent to the press section include the weld knots of the press section.
