Buying Guide: Key Purchase Considerations
Which tombstone type should you choose for LED tube retrofits?
- Non-shunted vs. shunted: Non-shunted tombstones are compatible with single-ended and certain dual-ended configurations, while shunted designs can simplify some ballast replacements. Consider your ballast type and wiring plan.
- Base compatibility: Most options support T8, T10, and T12 with medium Bi-pin bases. Verify your tube type before buying to ensure proper fit.
- Wattage and voltage: Look for a rating up to 660W and at least 600V to cover common LED tube and ballast combinations. This helps prevent overloading the socket.
- Material and fire safety: Many models use heat-resistant PC or PBT, with UL listing. This affects safety in retrofit environments and long-term reliability.
- Pack size: Choose based on project scope. Bulk packs save time for large facilities, while small packs suit one-off replacements.
- Wiring requirements: Some tombstones include wires, others require additional wiring. Plan for wire gauge (18 AWG typically) and the number of conductors needed.
- Installation complexity: Screw-type versus plug-and-twist designs impact ease of installation and the risk of wiring mistakes. Assess tool access and helper availability.
