Landscape post lights are mostly made of aluminum, iron, and steel. These three are different in how they are made, how long it takes to make them, how hard they are to make, and how they work.
1. Picking materials based on how long they last:
Aluminum has a low boiling point and is very flexible, so it can change shape when it gets too hot. It doesn’t last as long as steel and is not usually a good idea to use in windy places. On the other hand, steel lets you build walls that are thicker, which makes them stronger and more stable.
2. Picking materials based on how well they are made:
The material also affects how good the garden post lights are. Making cast iron and cast aluminum is a lot more complicated than making steel. For example, to make aluminum landscape post lights, the metal is first melted and then shaped with a special mold. The aluminum rod has different patterns carved into it. After it dries, it is galvanized and powder-coated. To make steel post lights, you just cut steel plates into tapered pieces and then use a rolling machine to roll them into post poles. Galvanizing and powder coating are the last steps after welding and polishing.
3. Choosing materials based on price:
The price of garden post lights varies a lot depending on the material. Post lights made of cast aluminum are 3 to 6 times more expensive than those made of steel because they are made in a complicated way, cost a lot of money, and come in unique shapes.
How to Install a Landscape Post Light:
Before you can put up a garden post light, you need to weld a foundation cage with M16 or M20 (common standard) bolts that meet the manufacturer’s flange specifications. After that, they dig a hole at the installation site that is just the right size. Put the foundation cage inside and pour cement concrete around it to keep it in place. You can put up the landscape post light after it has been fully set for 3 to 7 days. (Note: You need to lead out pre-buried pipelines while the foundation is being poured.)
The flange is an important part that connects the garden light pole to the ground. When you put up garden post lights, take the packaging off and look for any problems. For putting together and wiring, see the product manual. The basic steps are as follows: To put together the lamp, open the housing, add the light source and other electrical parts (see the electrical wiring manual), run the lead wire through the wiring hole to the bottom of the light pole, and then connect the lamp head to the light pole, making sure to tighten the screws carefully. Check that the commercial garden light flange is level with the bolts that are already in the foundation. After that, use shims or nuts to level the surface before tightening the installation nuts.
Wiring a Garden Post Light Circuit:
After you put it together, use the instructions and electrical specs to connect the wires. Please remember that the wiring needs to be grounded. To keep people safe, most landscape post lights already have a grounding terminal built in. Pick lights that spread light out evenly. Based on the purpose and shape of the lighting area, you should choose the type of light distribution for the luminaire. Select high-efficiency luminaires. For lighting that only satisfies visual function requirements, direct-distribution luminaires and open-type luminaires are recommended, provided glare control requirements are met.
Choose lighting fixtures that are easy to maintain and have low operating costs. In special locations with fire or explosion hazards, or environments with dust, humidity, vibration, or corrosion, lighting fixtures that meet the requirements of that environment should be selected. When high-temperature parts of the lighting fixture and its accessories are near flammable materials, fire protection measures such as heat insulation and heat dissipation should be taken. Lighting fixtures should have complete photoelectric parameters, and all their functions should comply with the relevant provisions of current standards such as “General Requirements and Tests for Luminaires”.
