Grow Light Cables & Power Leads
Replacement and extension cables for grow light fixtures, ballasts, and controllers, including power leads, interconnect cables, and driver extensions from LUMii, Telos, Photon, SANLight, DimLux, and Gavita. Essential for extending reach, daisy-chaining fixtures, or replacing a damaged original cable.
Common cable types you might need
Power leads connect your fixture or ballast directly to your mains supply. Interconnect/daisy-chain cables link multiple fixtures together so they can be controlled from a single point (useful for larger multi-light setups). Driver extension cables let you relocate an LED driver away from the fixture itself, helpful for reducing in-tent heat.
Matching connector types
Different manufacturers use different connector standards (IEC, RJ12, proprietary waterproof connectors), so always check that a replacement or extension cable matches your specific fixture or controller's connector type rather than assuming universal compatibility.
When to use an extension vs a replacement
If your original cable is too short to reach a power outlet or another fixture, an extension cable (rather than a full replacement) is usually the simpler, cheaper fix — provided the extension is rated for your equipment's power draw.
FAQ
Can I use a generic extension cable instead of a manufacturer-specific one?
For simple power leads, often yes, provided the rating (amperage, connector type) matches. For daisy-chain or driver-specific cables carrying control signals (not just power), always use the manufacturer-specified cable.
How do I know if my ballast is rated for an extended cable run?
Check your ballast's specification for maximum ignition distance — most HID ballasts have a rated maximum cable length between ballast and bulb, beyond which ignition reliability drops.
My cable feels warm during use — is that normal?
Slight warmth under load can be normal, but any cable that's hot to the touch, discoloured, or showing damage should be replaced immediately as a safety precaution.
