This step-by-step guide will focus on best practices for low-voltage landscape lighting, guiding you through the installation process to make sure your lamps are not only aesthetically pleasing and durable, but more importantly, safe and reliable.

Understanding Your Corten Lights
Before commencing any wiring work, you must understand the specific requirements of your Corten steel lights. Our products are engineered for enduring durability, making them the cornerstone of resilient outdoor landscape lighting.
Pre-Wire Check: Identifying Terminals and Seals
Corten steel lightings (such as our popular bollard lights or street lamps) are specifically engineered to withstand harsh weather conditions.
• Terminals: Most low-voltage Corten steel lamps feature two unmarked simple cables (positive and negative) for direct connection to low-voltage cable circuits. They operate at 12V or 24V AC/DC.
• Seals: Inspect the lamp head and cable entry points. The integrity of waterproof seals (at IP-rated connection points) is critical for long-term luminaire performance, particularly for weathering steel lighting exposed to humid environments.
Choosing the Right Bulb: LED is Essential
For any modern Corten steel pathway light or spotlight, LED bulbs have become an essential choice for the following reasons:
• Low Heat Output: LEDs generate minimal heat, safeguarding internal circuitry and the luminaire's delicate surface finish.
• Energy Efficiency: Their power consumption is exceptionally low, enabling a single standard low-voltage transformer to drive multiple fixtures.
• Extended Lifespan: LED design longevity matches that of the weather-resistant steel housing, significantly reducing maintenance requirements.
Tools and Materials You Will Need
To successfully install a DIY Corten steel light, the appropriate equipment must be provided.
Essential Tools: Shovel, Wire Strippers, Screwdrivers
• Trenching /Digging Tool: Used for excavating shallow trenches for cable laying (typically 6-8 inches deep).
• Wire Strippers / Wire Cutters: Used for neatly connecting wires and trimming cable ends.
• Screwdrivers (Flathead and Phillips): Used for securing terminal blocks inside transformers.
Required Materials: Low-Voltage Cable, Transformer, Connectors
• Low-voltage Cable: Employ direct-buried cable suitable for outdoor environments (typically 12 or 14 gauge). Thicker wire diameter (lower gauge number) permits longer power transmission distances with reduced voltage drop.
• Power Supply: A dedicated low-voltage landscape lighting transformer must be fitted to convert standard domestic AC power into safe 12V AC/DC. Ensure its capacity exceeds the combined wattage of all luminaires during the selection process.
• Waterproof Connectors: Used for reliable connections between luminaire cables and the main cable. Gel-filled twist connectors or crimp connectors are strongly recommended to achieve a permanent waterproof seal.

Step-by-Step Wiring and Installation of Corten Lighting
This section guides you through the complete process of wiring Corten steel outdoor lights, from start to finish.
Step 1: Plan Lighting Layout and Cable Routing
Before excavation, draw a layout diagram of required luminaire positions and measure the total distance to the transformer location. This ensures procurement of the correct cable length and determines the required wire gauge specification to prevent voltage drop.
Step 2: Install and Position the Transformer
The transformer must:
• Be Securely Fixed: Mount firmly to a wall, fence, or post near an outdoor RCD socket.
• Be Protected: Avoid direct sunlight and rain exposure; installation under eaves or a porch is recommended.
• Be Powered: Plug into the RCD socket, but keep it switched off until all wiring is complete.
Step 3: Landscape Cable Laying and Burial
• Trenching: Dig a shallow trench (6-8 inches deep) along the planned route.
• Wiring: Lay low-voltage cables with ample slack to ensure tension-free connections for each luminaire.
• Safety Note: Do not bury cables until Step Six. Maintain an accessible space for subsequent connection work.
Step 4: Prepare Wiring for Corten Steel Lights
Position the Corten steel light at its final installation location. For ground-mounted lights, drive the light post into the ground. Ensure the light's wiring is accessible for connection.
Step 5: Electrical Connection
This step is critical for ensuring a safe and effective power supply.
• Stripping: Using wire strippers, expose approximately 1/2 inch (1.27 cm) of bare copper wire at both ends of the main cable and the luminaire wires.
• Connection: Connect the light wires to the main cable. Polarity is generally not a concern in low-voltage systems, unless the luminaire uses specific DC LED bulbs. Connect one lamp wire to one conductor of the main cable and the other lamp wire to the second conductor.
• Sealing: Fit a waterproof cable gland over the connection and tighten securely. This sealing step is vital to prevent moisture ingress, causing short circuits, particularly critical for outdoor installations using Corten steel lights.
Step 6: Lights Fixing and System Testing
Upon completing all lighting wiring and sealing:
• Connect the Transformer: Terminate the main cable at both ends to the 12V or 24V terminals within the transformer housing.
• Testing: Activate the transformer by switching on the power supply. If the lights illuminate, the wiring is successful.
• Backfilling: Carefully re-bury the cable within the trench, taking care to avoid damaging the wiring or connectors.

Safety Tips and Best Practices
When installing heavy-duty landscape lighting systems, the importance of safety cannot be overemphasised.
Ensure Leakage Protection Sockets Are Used
Ground Fault Circuit Interrupters (GFCI) are designed to immediately cut off power upon detecting abnormal currents, preventing electric shock incidents. Never connect low-voltage transformers to non-GFCI sockets.
Ensure Waterproof Connections
The most common failure point in outdoor lighting systems is moisture ingress at connection points. Always use marine-grade or silicone-filled connectors to achieve permanent waterproof seals, particularly in harsh environments.
When to Contact a Licensed Electrician
While low-voltage wiring poses no safety risk to most homeowners, a licensed electrician must be engaged in the following circumstances:
• Installation of a dedicated 120V GFCI socket for the transformer
• Installation of complex systems involving higher voltages or specialised control devices
Maintaining Your Corten Steel Lights
The advantage of Corten steel is its low maintenance requirements, though basic upkeep ensures it performs at its optimum.
Clean Glass and Inspect for Debris
Regularly wipe the glass lenses of Corten lamps to remove dust, pollen, and debris, which can significantly reduce light output. Ensure drainage holes remain unobstructed to prevent water accumulation.
Seasonal Electrical Integrity Check
Conduct a quick inspection each spring: examine the main cable for any exposed sections due to corrosion, and verify all waterproof joints remain securely sealed and buried underground.
