Buying Guide: Key Purchase Considerations
- Compatibility: Verify base type (Bi-pin vs single-pin), lamp type (T8/T10/T12), and whether the tombstone supports shunted or non-shunted configurations for your ballast type and tube choice.
- Electrical ratings: Match maximum wattage and voltage to your intended tubes. Common ranges include 660W and 600V–608V, but confirm with your fixture and tube specifications.
- UL listing and material safety: UL-listed tombstones with fireproof PC or similar materials offer enhanced safety for commercial settings and retrofit projects.
- Wiring and installation: Consider wire length (10″–21″ variants) and whether the unit is dual-end powered or single-end powered. Plug-and-play designs save time in installation.
- Bulk options vs smaller packs: For large projects, bulk packs reduce per-unit cost and simplify inventory management; smaller packs may be better for maintenance or limited fixtures.
- Durability and environment: Look for heat resistance and durable housings suitable for long-term operation in office, factory, or retail environments.
- Compatibility with LED retrofits: If replacing fluorescent tubes with LEDs, ensure the tombstones are designed for retrofit applications and won’t impede LED performance.
- Warranty and brand support: Choose brands with clear warranty terms and readily available replacement parts in case of wear or damage.
When selecting a tombstone, weigh installation ease against long-term maintenance needs. For facilities with frequent upgrades, bulk packs from JESLED or Hortsun offer cost-efficient options, while JACKYLED and EZONPINZV models provide flexible wiring configurations for diverse fixture layouts. Always confirm tube compatibility and ballast requirements before purchase to ensure a safe, compliant retrofit.
