Lock & Seal 5′ Extension

The Lock & Seal 5’ Extension is a 5-foot lamp cord extension designed to give growers additional reach between a ballast and a reflector in their lighting setup. It supports cross-brand configurations through the use of adapters, allowing you to pair Hydrofarm ballasts with third-party reflectors, or Hydrofarm reflectors with third-party ballasts. Keep in mind that high-intensity discharge (HID) systems have ignitor range limits, so longer cord runs may not work reliably with all ballasts.

Lock & Seal 5’ Extension Specifications

The following table summarizes the key specifications for the Lock & Seal 5’ Extension based on available product documentation.

Why Choose the Lock & Seal 5’ Extension

When your ballast and reflector are further apart than a standard lamp cord allows, you need a reliable cord extension rated for grow-room use. The Lock & Seal 5’ Extension addresses that need directly:

• Extends your existing cord run by 5 feet — adds reach between a ballast and reflector without requiring new wiring or a full cable replacement.
• Supports cross-brand setups via adapters — the Lock & Seal range includes adapters that let you connect Hydrofarm ballasts to non-Hydrofarm reflectors, or Hydrofarm reflectors to non-Hydrofarm ballasts, giving you flexibility when mixing equipment brands.
• Part of a complete cord range — Lock & Seal offers a full selection of power supply cords and adapters, so you can source matching components from a single product family if you need additional extensions or different configurations.
• Straightforward installation — connects between the ballast output and the reflector socket using standard lamp cord connectors. No tools required for the connection itself.

One thing to be aware of before purchasing: high-intensity discharge (HID) lighting systems with magnetic or electronic ballasts include an ignitor that fires the lamp at startup. The ignitor has a maximum operating range, and adding cord length can place the lamp beyond that range. If you are running HID lights (HPS, MH, or CMH), verify your ballast’s ignitor range before adding a 5-foot extension. LED grow lights are not affected by this limitation.

Best Uses for the Lock & Seal 5’ Extension

This cord extension is best suited to growers who need modest additional cord length in an existing HID or compatible grow-room lighting setup:

• Repositioning a ballast remotely — mounting a ballast on a wall or shelf outside the canopy footprint while keeping the reflector centered over the plants. A 5-foot extension provides enough additional reach for most standard tent and room configurations.
• Mixed-brand lighting configurations — pairing a Hydrofarm ballast with a third-party DE or single-ended reflector (or vice versa) using the appropriate adapter alongside this extension.
• Reducing heat in the canopy zone — moving a hot-running ballast further from the canopy by extending the lamp cord rather than relocating the entire fixture.
• Replacement in existing setups — replacing a damaged or short lamp cord extension in a working system where the ballast and reflector are already at a fixed distance.
• LED driver positioning — where the driver unit needs to sit away from the fixture head; verify connector compatibility with your specific LED fixture before purchasing.

For a full-featured LED lighting solution that eliminates HID lamp cord concerns entirely, see the Gavita Pro 1700e LED. If you need power cords rather than lamp cord extensions, the Faven Chroma Power Cords 120V are worth considering.

Compatibility & Operating Range

The Lock & Seal 5’ Extension is designed for use in grow-room lighting circuits connecting ballasts to reflectors. Key compatibility points:

• HID lighting (HPS, MH, CMH): Compatible with systems where the ballast’s ignitor range permits the added cord length. This varies by ballast manufacturer and model. Check the ballast specification sheet for maximum lamp cord length before installing any extension.
• Hydrofarm equipment: The Lock & Seal range is designed to work with Hydrofarm ballasts and reflectors. Adapters in the same product line allow cross-brand connections.
• Non-Hydrofarm equipment: Use the appropriate Lock & Seal adapter (sold separately) when connecting Hydrofarm components to other brands.
• LED systems: LED fixtures and drivers do not use ignitors, so ignitor-range restrictions do not apply. However, verify that your LED fixture uses the same cord connector type as this extension before purchasing, as connector standards vary by manufacturer.

If you have a question about whether this extension is compatible with your specific ballast model, consult your ballast documentation or contact your sales representative as noted in the product description.

Usage Guidelines

Follow these guidelines when installing a lamp cord extension in a grow-room lighting circuit:

1. Power off the circuit completely before connecting or disconnecting any lamp cord components. Do not work on a live circuit.
2. Check the ballast ignitor range in your ballast’s specification sheet. Add up all cord lengths in the circuit (ballast output cord + extension) and confirm the total is within the manufacturer’s stated maximum.
3. Connect the extension between the ballast output and the reflector socket. Lock & Seal connectors are designed to seat securely; ensure each connection is fully seated and locked before powering on.
4. Route the cord safely — avoid pinching, sharp bends, or routing near heat sources. Keep the cord clear of drip irrigation lines and standing water.
5. Power on and verify — the lamp should strike and reach full brightness on the normal warm-up cycle. If the lamp fails to strike or flickers, the cord extension may exceed the ballast’s ignitor range; remove the extension and consult your ballast documentation.
6. Inspect regularly — check connectors and cord insulation for heat damage, cracking, or discoloration at each grow cycle.
