The size of the LED chip is expressed by the side length, and the quality of the large chip LED is better than that of the small chip. The price is naturally more expensive, and the price of the LED flat lamp will be higher.
2. Wafers of different prices
The luminous body of LED is a chip. Different chips have very different prices. Chips in Japan and the United States are more expensive. Generally, the price of chips in Taiwan is lower than that in Japan and the United States, which also determines the price of LED panel lights.
3. The length of LED life
The life of LED flat lamp is determined by the light attenuation. When the light decay is small, the life is long, but the price is also higher.
4. LED with consistent wavelength
LED emergency panel light manufacturers also emphasized that in order to choose pure color LED flat panel light products, the manufacturer must have an LED spectrophotometer to manufacture LEDs with consistent wavelengths and consistent colors. Because the colors are required to be consistent, the price is higher.
