1. The high pole lamps in Guangzhou's inner ring road still remain active, and their heat issue has not been resolved. In the early years, over 80 bases were installed along the inner ring road, and last year, the lighting project on Guangyuan East Road was launched with more than 140 high pole lamp bases. The one-sided lighting on the road, especially the use of high pole lights in urban areas, is controversial.
2. Due to the current "low price" bidding standard, and the lack of technical oversight in certain regions, many low-price bidders are forced to cut corners, leading to poor quality work. For example, a simple 25-meter high pole lamp can cost only tens of thousands of yuan, while a fully functional, technically advanced model that meets industry standards requires over 100,000 yuan. If the design does not specify detailed technical requirements, the winning bidder will likely install the basic version. I believe there are serious concerns about the quality of the high pole lamps used in the first and second phases of the Guangyuan East Road lighting projects.
Therefore, the principle of “lowest price†in bidding contains many loopholes. While investors may save some money initially, this short-term saving often leads to higher long-term costs due to maintenance, repairs, and potential safety issues.
Common problems with these "simple" high pole lamps include:
(1) Lack of safety guarantees for critical components, such as no support or anti-fall device on the lamp panel, which violates the current industry standard "Technical Conditions for High-Pole Lighting Facilities" (CCJ/T3067).
(2) Slow lifting speed. For instance, the lamp panel on Guangyuan East Road’s 30-meter high pole lamp lifts at 0.7 meters per minute, taking over an hour to raise. Adding mobile loading equipment increases the time to two hours.
(3) Most lifting mechanisms are makeshift—just a motor connected to a gearbox and a roller added. This results in misalignment, gear damage, and frequent jamming or dropping during operation.
3. The lifting mechanism for the lamp panels often causes difficulties in installation and removal due to differences in design, manufacturing, and operational skills. In my view, while automatic hooks used in the U.S. and France are not perfect, the most practical and simple solution is the "automatic screw-in trough support (unloading) device."
4. Given the humid southern climate, it is not suitable to use built-in motors in light poles, nor is the moving (loading) type recommended.
5. When designing road lighting, especially when using high pole lamps, detailed technical specifications must be included. Bidding processes should not ignore potential loopholes in this regard.
6. The lifting speed of high-pole lamps is either too fast or too slow. It is recommended that the lifting speed be between 2 to 5 meters per minute. Currently, there is only an upper limit specified, but no lower limit.
The author of this article has submitted multiple manuscripts on high pole lamp technology (mainly mechanical aspects), operation management, and safe usage to the "Outdoor Lighting" magazine. Today, based on my experience with over 500 high pole lamp bases in Guangzhou (including more than 100 not managed by the street lighting department), I have observed various types of high pole lamps, both domestic and imported, in terms of construction and operation.
