Advantages of single-arm and double-arm street lighting poles

In road lighting and municipal engineering construction, the two most common types of street lamp posts are single-arm and double-arm poles. The different structure design is quite different in the suitable scenes and benefits of usage. To many project procurement and construction personnel, they are a source of confusion when it comes to pole selection. Tianxiang compares the core advantages of the two road light poles from four aspects: suitable scene, lighting effect, cost, installation and maintenance.

I. Scenario Adaptability

Single-Arm Street Lighting Poles:

First of all, they are applicable to various situations and have good compatibility. They are able to perfectly fit in narrow road surfaces such as rural roads, community walkways, park paths, and urban auxiliary roads, without wasting the space.

Secondly, they give a flexible and free layout. They can be installed on one side according to the direction of the road and the layout of the green space, adapting to the lighting needs of small sites without blind spots.

Double-Arm Street Lighting Poles:

First, they are designed for a wide road surface, mainly suitable for wide roads such as urban main roads, two-way lanes, and municipal avenues, in line with mainstream traffic road lighting standards. Secondly, there is a greater degree of uniformity. The symmetrical structure guarantees a unified and aesthetically pleasing road lighting layout, in accordance with the standardized and regulated engineering construction requirements of cities.

II. Lighting Effect

Single-Arm Street Lighting Poles:

First, it produces a sharp, focused beam of light. The light is projected directionally from one side, concentrating on that side of the road surface, thereby minimizing light scattering and preventing light waste. Secondly, it is free from glare. Single-sided lighting does not cause glare to pedestrians or vehicles traveling in the opposite direction and provides a better experience to pedestrians on smaller roads.

Double-Arm Street Lighting Poles:

First, it provides bidirectional full coverage. Two lights mounted on one pole can illuminate both sides of the road simultaneously, eliminating blind spots and greatly enhancing the overall brightness of the road surface. Second, it provides high illuminance uniformity. The light distribution is even and symmetrical, which can completely avoid the uneven light on the road surface and meet the high-standard lighting requirements of main roads.

III. Cost

Single-Arm Street Lighting Poles:

First, it’s cheaper in materials. It is produced and processed at the lower pole at a lower cost. The structure is simple and less material is used, so it is affordable per unit. Second, it requires the purchase of fewer accessories. It does not need any complicated parts and hence can be used for small scale, decentralized lighting projects and also helps in reducing the overall budget.

Double-arm Street Lighting Poles:

First, buying in quantity saves money. This way, when installing lights in batches on main roads where one pole replaces two, less foundation and embedded parts are needed.

Secondly, the total cost is controllable. Compared with single-arm lights installed on both sides, it saves a lot of labor and infrastructure costs, so it’s more economical for large-scale projects.

Ⅳ. Installation and Maintenance

Single-arm Street Lighting Poles:

Firstly, installation is easier. Lightweight poles with a simple structure enable assistance during construction by a single person. It has a simple foundation construction and a short construction period.

Secondly, it is inexpensive to maintain. Faults only affect one side of the light fixture, which simplifies the inspection and replacement of parts and reduces the pressure of post-construction maintenance.

Double-arm Street Lighting Poles:

First, the frequency of construction is decreased. This means that the number of poles for the same section of road is halved. This reduces the number of points and procedures of construction.

Second, the operating and maintenance efficiency is better. The centralized deployment enables staff to conduct regular inspections, which greatly improves the overall efficiency of the operation and maintenance of the main road street lights.
