Lamp Holders (Fluorescent Tube Tombstones)

These lamp holders (also known as fluorescent tube lampholders / tombstones) are electrical socket components used to mount and power linear fluorescent or LED tube lamps in luminaires. They are designed to securely hold the lamp pins and provide reliable electrical contact, ensuring stable operation in fixtures such as battens, troffers, vapor-tight luminaires, and industrial lighting housings.

The models shown represent a range of common lampholder styles and mounting options used for different tube bases and fixture designs—typically including G13 (T8/T12) and G5 (T5) pin configurations (depending on the exact part number), with variations for surface mounting, snap-in mounting, screw mounting, and bracket mounting. Some versions are rotary lock types (quarter-turn) for improved pin retention, while others are fixed-entry types for fast assembly.

Key Features

• Compatible tube bases (model dependent):
  • G13 (T8 / T12 fluorescent & LED tubes)
  • G5 (T5 fluorescent & LED tubes)
• Secure pin contact: spring/pressure contact system for stable electrical connection
• Multiple mounting formats: snap-in, screw mount, bracket mount, and panel mount options
• Rotary lock options: quarter-turn locking types available for improved retention (model dependent)
• Heat-resistant housing: made from durable insulating plastic suitable for luminaire operating conditions
• Fast installation: designed for quick fixture assembly in production or maintenance replacement

Technical Specifications (Typical / Series-Dependent)

Exact ratings depend on the specific model number (1–17). Values below represent common lampholder specifications.

• Rated Voltage: typically 250V AC (some series may be rated higher)
• Rated Current: typically 2A–4A (higher ratings available in some models)
• Base Type: G13 or G5 (depending on model)
• Contact Material: copper alloy / brass contact springs (model dependent)
• Body Material: flame-retardant insulating plastic (commonly PBT or PC; model dependent)
• Wire Connection: push-in or screw terminal (depending on model), suitable for standard luminaire wiring
• Mounting Options:
  • snap-in panel mount
  • screw mount base
  • bracket/bridge mount for dual holders
• Operating Temperature: suitable for typical luminaire internal temperatures (series dependent)

Common Applications

• T8/T12 tube luminaires (G13 holders): battens, troffers, industrial fixtures, vapor-tight fittings
• T5 tube luminaires (G5 holders): slim battens, office troffers, continuous row systems
• Replacement parts for damaged, cracked, or loose lampholders in existing fixtures
• New luminaire manufacturing and assembly
