Difference Between 20 Yuan LED Lamps and 200 Yuan LED Lamps

Difference one: different channels

Daily expenses of luminaire stores include: rent, electricity, personnel costs, freight transportation costs, storage costs, and goods cost. Therefore, lamps and lanterns in physical stores will naturally sell high prices. Online shopping can be shipped directly from factories, thus eliminating many intermediate links.  Because this sales mode can be well controlled from cost, the price is relatively low. In some cities' group buying meetings, the lowest price discount is produced because the manufacturers are directly present, and the cost performance is quite high.

Difference two: LED performance is different

(1) brightness: the brightness of LED bulb is expressed by lumen, the higher the lumen number, the brighter the lamp, the more expensive the price.

(2) antistatic ability: LED with strong antistatic ability, long life and high price. Usually, LED with an electrostatic strength greater than 700V can be used for LED lighting.

(3) wavelength: LED with the same wavelength. The color is the same. If the color is uniform, the price is high. It is difficult for manufacturers without LED spectrometers to produce pure color products.

(4) leakage current: LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage current. LED with large leakage current has short life and low price, otherwise the price is high.

(5) luminescence angle: LED with different uses, its luminous angle is not the same. The light angle, the price is high. Such as full diffusing angle, full light distribution, 360 degree luminescence and so on, the price is higher.

(6) life: the key to different quality is life, and life is determined by light decay. Light decay, long life, long life and high price, the average life expectancy of LED lamps is higher than traditional lamps and lanterns.

(7) LED chip: the luminous body of LED is the chip, and the chip is equivalent to the heart of LED lamp. Chips in Japan and the US are more expensive. The prices of LED chips in Taiwan and Mainland China are lower than those in Japan and the United States. Most of the prices of LED lamps are concentrated on chips.

(8) chip power size: the quality of a single high power chip LED is better than that of a single chip, and the price is directly proportional to the chip power.

(9) colloid: colloid of ordinary LED is generally epoxy resin. If the colloid contains the function of anti ultraviolet and fire retardant, the price is more expensive. High quality outdoor LED lighting should have anti ultraviolet and fire protection functions. Good colloid is safer in daily use, and can effectively avoid accidents such as short-circuit and other unexpected situations.
