Buying Guide
What should you check before buying tombstone sockets? First, verify the base type (T8, T10, T12) and pin count (Bi-pin vs FA8) to match your tubes. Consider whether your fixture will be dual-end powered or single-end powered, as some sockets are designed specifically for one configuration. Look for UL or other safety certifications and fireproof materials like PBT to minimize risk in long-term use. If you’re retrofitting to LED tubes, ensure the socket supports up to 600V and 660W to handle typical LED and fluorescent loads. For large projects, buying in bulk can reduce per-unit costs and simplify inventory management. Finally, check if wiring is included; some models require you to supply 18 AWG or 18- or 21-gauge wires depending on the kit.
Key Considerations
- Compatibility: Ensure the socket matches your tube type (T8/T10/T12) and pin configuration (Bi-pin or FA8).
- Safety: Prioritize UL-listed, fireproof materials for long-term reliability.
- Wiring: Consider whether wires are included and if the gauge fits your fixture’s wiring plan.
- Durability: Fireproof plastics and robust construction extend fixture life in commercial use.
- Installation: Choose sockets that align with your installation skill level and fixture design.
FAQ
- What is a tombstone socket? A tombstone socket is the electrical connector that accepts a fluorescent or LED tube with a Bi-pin or FA8 base and provides dual- or single-end power to the tube.
- Can tombstone sockets be used with LED tubes? Yes, most are designed for LED retrofit tubes and fluorescent replacements, with safety certifications and compatible voltage ratings.
- Do I need wires with tombstone sockets? Some packs include wires, while others require you to provide 18 AWG or similar wires; check product details.
