As it is easy for everyone to enter into led industy, the production stanard is not consitstence with the testing machines and technology shortage. so it lead to the mess market which is flooded with different quality. meanwhile, as the led market competition is very sever, the price is up and downs, the apperence, structure and fuctions almost is same, but the price has more than double difference, enable many customer are very confused.
Here we are sharing our knowledge to introduce what decisde led lighting price
Wavelength is the physical one who determine the emission color. the wavelength is Same, the led lighting colors will be consistency, that is so-called pure good. LED Lighting Fixture consist many light emitting tubes, if choosing same wavelength, the lighting cost will increase. However, most users do not understand that the color purity indicator fall, of course, the cost of production is also down, it can be sold at lower prices.
In addition, such high requirements of consistent color, it needs the separation device for led, and it will increase the cost of production.
2. LED Chip
4. Chip Size
5. Leakage Current
6. Antistatic ability
Antistatic ability is the diode reverse voltage withstand capability. If antistatic ability is bad, the LED diode easily breakdown; on the contrary, the Antistatic ability of LED diode is strong, then it will have long life, stable quality, accordingly it has higher price.
LED Lighting quality is the key to lifespan. The index measure of the life is the LED lighting fades a few percent of initial brightness, not bright anymore. Usually the larger the working current it is, more quickly the LED light fades, and the shorter the life expectancy has. Of course, long life, the price is high.
8. viewing angle
LED lighting fixutre has different emission angle for different usage. For Special light-emitting angle, it has high prices. If all diffusion angle, and the price is higher.
Ordinary LED lamps use generally an epoxy resin glue. if the glue add a UV proof and fireproof material, the price is more expensive. high-quality outdoor LED lighting should be UV resistence and fireproof, the price is not cheap.
To be concluded, we should know LED lighting market is a chaotic market. This it had a negative impact for LED Lighting application. After we learn the above knowledge, we should be careful to identify, compare, buy those stable quality, reputable company’s products, not to buy the product ridiculously and crazy low prices. Because there is no free lunch in the world.
