Huanengshi is a brand of Zhongshan Polyland Lighting Technology Co., Ltd., the company was founded in 1999, is a professional enterprise engaged in energy-saving lighting electrical products, research and development capabilities are good, and South China University of Technology, Taiwan Jingyuan (EPISTAR) have cooperative relations, with more than 100 innovative technology patents.
 
Polylane is not small, the plant covers an area of 20,000 square meters, with an annual output value of 4-500 million yuan of production and supply capacity, the annual production of traditional light sources, LED light sources and electronic ballasts up to 20 million, covering home lighting, commercial lighting, industrial lighting and other fields, products are exported to Europe, America, Southeast Asia and other countries and regions.
 
Although Polyland has strong strength in the field of daily lighting, it has only been involved in the field of ultraviolet disinfection for a short time, and it was not until 2017 that it launched its own brand Huanengshi, which is a new brand. In view of the fact that first-line brands such as Philips and Shelllight have dominated the market for many years, Polyland chose to break through in terms of price and design, and its price of less than 200 yuan and the swan-shaped lamp stand have indeed made Huanengshi famous, ranking among the top ten in sales on major e-commerce platforms, second only to Philips and Shellright.
 
However, the brand history of Huanengshi is very short, has not yet undergone enough market test, although the price has a huge advantage, there are still some users to evaluate its ultraviolet lamp "disinfection effect is not obvious, the lamp is easy to break, the packaging is poor", performance and quality control ability still need to be improved, but for the current point of view, it is a choice for low-cost ultraviolet lamp.
 
From the perspective of the product line, Huanengshi's 4 ultraviolet lamps are all lampholders, with relatively large power, 36W and 60W are available, and the price is about 79-200 yuan, which is quite affordable. Two of them are conventional products, surrounded by metal strips for support and protection, and the other two are more special, one without a metal frame, and one with a swan-shaped light stand.
 
The simple ultraviolet lamp has no outer cover, and the whole lamp only has a lamp tube and a base, so the price is further reduced, and the ozone-free and ozone models are only 79 and 89 yuan respectively. Although the weight of the base is not small, it will not be dumped by large external forces, but the lamp tube is always lacking protection, once it is knocked over by children or pets, it is easy to damage the lamp, and then cause injury, so it should be placed on a flat surface as much as possible when in use, and take good care of children and pets.
 
The ultraviolet lamp of the swan-shaped lamp holder is the face of Huanengshi, and it is also a clear stream in the ultraviolet lamp. Generally speaking, ultraviolet lamps are mainly practical, manufacturers rarely make a fuss about the appearance, but this lamp is obviously not out of the ordinary, its streamlined lamp head, swan neck handle, hollow swan neck bottom and a series of designs, etc., have given the lamp holder an elegant image, and will not block the irradiation of ultraviolet rays, while maintaining practicality and has a certain decorative effect, the price is below 150 yuan, the cost performance is very high, but only 36W a power, more suitable for about 40 square meters of space.
