We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.

Centrifugal pump classification and selection
First, the centrifugal pump classification According to the nature of the liquid being transported can be divided into: (1) The pump is used to transport clean water and physical, chemical properties similar to water, clean liquid. (2) corrosion-resistant pump used to transport acid, alkali and other corrosive liquids. (3) The pump is used to transport petroleum products. Second, the choice of centrifugal pump (1) according to the nature of the liquid being transported and operating conditions to determine the type; (2) according to the flow (usually by the production tasks) and calculate the pressure head required in the pipeline to determine the pump model Or product catalog); (3) If the viscosity and density of the liquid to be transported differ greatly from that of water, the characteristic parameters of the pump should be calculated: flow rate, pressure head and shaft power. When choosing a centrifugal pump, there may be several types of pumps that meet the requirements of operating in the optimum range at the same time. In this case, you can determine the operating points of each pump, compare the efficiency of the operating point, the preferred choice. Centrifugal pump is characterized by liquid delivery capacity, uniform flow, but the resulting pressure is not high, and the pressure head with the flow changes.
