Lock & Seal 5' Extension

Secure 5-Foot Cord Extension for HID Ballast-to-Reflector Wiring

The Hydrofarm Lock & Seal 5-Foot Lamp Cord Extension adds reach between an HID grow light ballast and reflector without introducing a loose or failure-prone connection point. Its locking connector keeps the ballast-to-reflector link secure, so the cord resists accidental disconnection during normal handling around a grow space.

Hydrofarm sells a complete range of power cords, adapters, and extensions built around this same Lock & Seal connector, so growers can standardize their lighting wiring on one system. Adapters let a Hydrofarm ballast connect to a third-party reflector, or a Hydrofarm reflector connect to a third-party ballast, when a setup mixes brands.

Key Features & Benefits

• Lock & Seal Connector — Locking design keeps the ballast-to-reflector connection secure during routine handling.
• 5-Foot Length — Adds 5 feet of usable reach in the lamp cord run between ballast and reflector.
• HID Compatible — Built for HID grow light systems, including HPS and MH setups.
• Cross-Brand Adapters Available — Hydrofarm sells adapters that connect its cords to other brands' ballasts or reflectors.
• Part of a Full Cord Line — Fits into Hydrofarm's broader lineup of grow light cords, extensions, and adapters.

When to Use This Extension

This extension is for growers who need extra lamp cord length between a ballast and reflector in an HID setup — for example, when a ballast has to sit further from the fixture than the stock cord allows, or when a remote ballast mounting layout calls for it. It fits both single-fixture home setups and multi-light commercial rooms running Hydrofarm ballasts.

About Hydrofarm and Lock & Seal Cord Length Limits

Hydrofarm has manufactured grow room equipment, including HID lighting components, for close to five decades. Its Lock & Seal cord system is built specifically for ballast-to-reflector wiring, but growers should check ignitor range before extending any HID cord, since some capacitive-ignitor ballasts have a rated maximum cord length beyond which the lamp will not strike reliably.

Frequently Asked Questions

What connector type does this extension use?

The Lock & Seal extension uses Hydrofarm's locking connector design, which secures the ballast-to-reflector connection. That locking action reduces the risk of the cord working loose during setup or normal grow-room movement.

Is it compatible with all HID ballasts?

The extension is built for Hydrofarm ballasts and reflectors. Hydrofarm also sells adapters for connecting to other brands, so a mixed-brand lighting setup isn't ruled out.

How do I know if my HID system supports this extension?

Check your ballast manufacturer's documentation for a maximum rated cord length before adding this extension. Some capacitive-ignitor ballasts have specific ignitor range restrictions, and exceeding that range can cause the lamp to strike unreliably or not at all.

Can I use this with MH and HPS bulbs?

Yes. The extension is compatible with HID systems running either metal halide (MH) or high-pressure sodium (HPS) lamps, since it extends the ballast-to-reflector power connection rather than the lamp circuit itself.

What adapters are available?

Hydrofarm offers adapters that let a Hydrofarm ballast connect to a third-party reflector, or a Hydrofarm reflector connect to a third-party ballast. That flexibility is useful for growers running mixed-brand lighting equipment.
