At present, the quality of 100w outdoor slim led floodlight lamps on the market is uneven. The prices of lamps with the same power are several times different. Whether the price is high or the quality is worrying. Now I will analyze the extremely cheap 100w outdoor slim led floodlight lamps on the market. So that you can buy qualified lamps with high quality and low price, so as to avoid future worries.

　　 As the saying goes, you get what you pay for, the price is extremely cheap, and the cost is not high. Buying is not as good as selling, and he will make money no matter how cheap, and no one will do business that loses money. The result is that the more the lamps are made, the lower the price, but the quality cannot be guaranteed. There are a few points to let you know the tricks of low-priced lamps.

First of all, its light-emitting chips are inferior products, which is reflected in the luminous efficiency. The luminous efficiency of a single chip is 90LM/W, and the efficiency of the whole lamp is even lower, generally below 80LM/W. Now the large-brand light-emitting chip is at least 140LM /W above, this is incomparable, and some people say that it’s not as efficient as it is to be bright. They don’t know what it brings is a large amount of heat. As time goes by, the light decay will expand rapidly, and it will not take a year or two. Scrapped.

　　Secondly, the selection of the drive power supply. The price of the power supply of the same specification varies greatly due to the selection of accessories, and the service life will also vary greatly. Low-priced power supplies generally start to be damaged in a large area after two years, but high-quality power supplies generally have a warranty of more than 5 years and a service life of more than 7, 8 years. The maintenance cost is greatly reduced.

Thirdly, the design and materials of the Led Street Light Factory radiator are also critical. The heat dissipation design of a good lamp is scientific and reasonable, and the heat dissipation is fast. The temperature rise of long-term lighting does not change much. It is not hot to the touch, but it blindly reduces the cost. The lamp will be hot when the light is on for a while, it will also affect the normal power of the lamp, and will accelerate the light decay of the lamp.
