1. Luminance
Different luminance has different price. In addition, the LED light fixture must be suitable for the standard of laser classⅠ.
2. Antistatic ability
The stronger the antistatic ability of LED is, the longer the lifetime and the higher the price are. In general, the antistatic ability of LED light fixture is always larger than 700V.
3. Wave Length
If the wave length of LEDs are the same, so do the colors, then the price is much higher. So far, only LED spectrophotometer can produce pure color fixtures.
4. Leakage current
LED Flood Lighting is a unidirectional and conductive luminophor. If there's any reverse current, it is named as electric leakage. The larger the leakage current of LED is, the shorter the lifetime and the lower the price are.
5. Beam angle
Different application of LED has different beam angle. Special beam angle is high in price, such as diffuse angle.
6. Longevity
The key point of different quality lies in longevity, which is determined by lumen depreciation. If the lumen depreciation of LED light fixture is small, the longevity is long while the price is high.
7. Chip
The luminophor of LED Flood Lighting is chip. Different chip has large distinction in price. Generally speaking, import chip is much higher than Taiwan and homemade chip. In addition, the size of chip also influences the quality of LED, while the price is proportional to size of chip.
