Why Choose Our Power Cords + Accessories
Designed for controlled-environment agriculture, our electrical accessories are built to withstand humidity, temperature swings, and continuous cycles. Expect rock-solid connectivity, correct wire gauge for load, proper plug standards, and accessories that reduce failure points while improving energy efficiency.
Key Benefits
• Safer installs with correct voltage and plug types (120/240/277V)
• Optimized cable gauge to reduce voltage drop and heat
• Compatibility with common LED drivers, ballasts, and controls
• Ruggedized jackets and strain relief for high-duty environments
• Faster deployment with ready-to-use lengths and adapters
Uses in Greenhouses, Indoor Farms & Vertical Racks
Power LED grow lights, controllers, circulation fans, sensors, and irrigation controllers; daisy-chain compatible fixtures; extend runs safely from distribution to canopy rows; adapt regional or site-specific plug standards; and organize power distribution on benches, trusses, and racks.
Correctly matched cords and adapters prevent nuisance trips, reduce heat at connections, and protect fixtures and drivers. Using the right voltage and gauge improves efficiency and extends component life—so you maintain consistent light output, uptime, and harvest quality.
Types of Power Cords & Electrical Accessories
By Connector
• IEC C13/C14, C19/C20 for many LED fixtures and drivers
• NEMA straight-blade (5-15P, 6-15P/20P) for 120/240V circuits
• NEMA locking/twist-lock (L5/L6/L7) for secure, high-duty connections
• Waterproof/IP-rated and quick-disconnect connectors for wet zones
By Application
• Extension cords sized for continuous load
• Daisy-chain jumpers for compatible LED luminaires
• Plug adapters and pigtails to match facility standards
• Power strips, GFCI and surge-protected distribution
Frequently Asked Questions
What are the parts of a LED grow light?
Typically: LED boards/modules, heat sink, driver (power supply), housing, connectors (often IEC), mounting hardware, and controls/dimming leads (e.g., 0–10V or RJ connectors).
How many amps does an LED grow light use?
Amps ≈ Watts ÷ Volts (× 1 ÷ Power Factor). Example: 600 W at 120 V draws ~5.0 A (600/120) assuming PF ≈ 1. At 240 V the same light draws ~2.5 A.
How much power does a 600W LED grow light use?
If the fixture’s rated input power is 600 W, wall draw is ~600 W at full output. Actual draw can vary slightly by driver efficiency and dimming level.
What cable is needed for LED grow lights?
Use cords that match the fixture connector (e.g., IEC C13/C14) and circuit voltage (120/240/277 V), with proper gauge (14 AWG up to 15 A, 12 AWG up to 20 A, 10 AWG up to 30 A) and a jacket rated for your environment.
Do LED grow lights need a special power supply?
Most include an internal driver matched to 120/240/277 V input. Some systems use external drivers—always verify input range and connector type per the manufacturer.
Do you need special wiring for LED grow lights?
Use standard electrical wiring that meets local code and the fixture’s voltage/current. 277 V or three-phase work should be installed by a qualified electrician.
Different types of power cords for LED grow lights?
IEC (C13/C14, C19/C20), NEMA straight-blade (5-15P, 6-15P/20P), NEMA locking (L5/L6/L7), waterproof quick-connects, daisy-chain jumpers, and heavy-duty extensions.
Differences between 120, 240 and 277V power cord?
They differ in plug type, insulation and voltage rating. Higher voltage lowers current for the same wattage, which can reduce heat and voltage drop when properly sized.
Do the cable gauge matter?
Yes. Undersized wire overheats and causes voltage drop. Match AWG to current and run length (aim <3% drop): 14 AWG ≤15 A, 12 AWG ≤20 A, 10 AWG ≤30 A (check code).
