(2) whether the product’s rated voltage range ，color temperature, precautions, safety instructions, applicable environmental , etc. are marked clearly,
2, product price comparison
Due to LED lamps special production process, the cost is relatively high. The average domestic price of LED lights are in the forty to fifty or more, imports is higher.

In addition, the color of the lamp must be positive, lamp light color does not flash. After LED lighting is started, we can detect the heat by contacting with the product surface temperature, and if the product surface temperature continue to rise in one hour, rather than a maximum temperature stabilized at 30 minutes, then do not select the product, thermal reasons results in reducing product life.
The lighting time of LED flood light is longer than other LED lights, has been applied to outdoor long decorative lighting, its unique glass shade and light aluminum body coated with high thermal conductivity and high heat dissipation material ensure it has advantage of waterproof dustproof and high heat dissipation capability, but it can not guarantee its quality must be excellent, according to above particular， we can also judged it is good or bad, of course, it is difficult to find good professional lighting companies ahead of peers, Li Sida lighting www. lead-lighting.com is undoubtedly one of these。It is known as its high quality products and unique product and has been praising by domestic and foreign for a long time.
