The technology is becoming more and more mature, and the high-power LED light source can meet the needs of general street lamps. The general high-pressure sodium lamp has a luminous efficiency of 100LM/W. The commonly used high-power LED is 50-60LM/W. It can reach 80LM/W with foreign LED chips. The higher the luminous efficiency, the better the energy saving effect. This is also the choice. One of the most important indicators of LED street lights.
Due to the high technical content and complex composition of LED street lamps, some high-power lamp holders will weigh far more than ordinary high-pressure sodium lamps, so the requirements for the corresponding supporting materials are higher. However, some LED street lamp manufacturers have reduced the weight of the LED lamp head as much as possible, from about 30 kilograms of the original single lamp head to more than 10 kilograms, and the weight reduction has further declined.
The emergence of white LEDs is a substantial step in the LED's transition from the identification function to the illumination function. White LEDs are closest to daylight and better reflect the true color of the illuminated object, so from a technical point of view, white LED is undoubtedly the most advanced technology of LED. White LEDs have begun to enter some applications, and emergency lights, flashlights, flashlights and other products have come out one after another, but because of the high price, it is difficult to popularize. The premise of the popularity of white LEDs is that prices are falling, and the price decline must be made after the white LEDs form a certain market size. The integration of the two depends on technological progress.
The biggest advantage of LED lights is energy saving and environmental protection. The luminous efficiency of light reaches 100 lumens/watt or more, the ordinary incandescent lamp can only reach 40 lumens/watt, and the energy-saving lamp is also around 70 lumens/watt. Therefore, the same wattage, LED light effect will be much brighter than incandescent and energy-saving lamps. The brightness of 1 watt LED lamp is equivalent to about 2 watts of energy-saving lamps. The 5 watt LED lamp consumes 5 degrees in 1000 hours, the life of LED lamp can reach 50,000 hours, and the LED lamp has no radiation.

Q1:For same power,why different suppliers with different brightness?
A1:Different chips,or same chip but different brightness version.The brightness will be different.But for same chip and same brightness version,the brightness will be slight difference.But please make clear the brightness difference between LEDs and lamp fixture.
Q2:What is colour temperature?
A2:Kelvin is a way to measure "temperature", the light from LED lights emit a certain color, which we have catagorized in CTT(kelvin).For example, a warmer (lower color temperature) light is often used in public areas to promote relaxation, while a cooler (higher color temperature) light is used to enhance concentration in offices.
Q3:Can we get support if we have our own market position?
A3: Please inform us your detailed market demand,we will discuss and propose helpful suggestion for you,to find the best solution for you.
