The construction of LED luminaires seems simple, but there are many details that are precisely the source of the difference. Due to the increasingly fierce price war, the products with almost the same appearance, structure and function have a price difference of 2-3 times. The main reasons for the price difference are the following:
The brightness of the LEDs is different and the price is different. Just like traditional incandescent lamps, the price of high wattage lamps is high. The brightness of LED bulbs is expressed in lumens. The higher the lumens, the brighter the lamps and the more expensive they are.
LEDs with strong antistatic properties have a long life and are therefore expensive. LEDs with an antistatic over 700V are usually used for LED lighting.
LEDs with the same wavelength have the same color. If the color is the same, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.
An LED is a unidirectionally conductive illuminator, and if there is a reverse current, it is called leakage. LEDs with large leakage current have short life and low price, and the price is high.
LEDs with different uses have different illumination angles. Special lighting angle, the price is higher. Such as full diffusing angle, full light distribution, 360 ° lighting, etc., the price is higher.
The key to different qualities is lifespan, and lifespan is determined by light decay. Low light decay, long life, with long life comes with high price. The average life of LED lamps is higher than that of traditional lamps.
The illuminator of the LED is a chip, and the price of the chip varies greatly. The chips in Japan and the United States are more expensive, and the price of LED chips from Taiwanese and Chinese manufacturers is lower than that of Japan and the United States. Most of the price of LED lights is concentrated on the chip, and the chip is equivalent to the heart of LED lamps.
LED lamps with too low prices are more likely to be manufactured with inferior materials and rough processes. Not only are they not guaranteed in terms of safety, but they are also doubtful in terms of product quality. Therefore, when consumers choose LED lights, they must see the product parameters and product quality.
