1. Brightness
Luminance L: The luminous flux of a luminous body per unit solid angle and unit area in a specific direction. Unit: Nitre (cd/㎡). Luminous flux φ: the sum of the amount of light emitted by the luminous body per second. Unit: Lumen (Lm), which indicates how much the luminous body emits, the more luminous, the greater the number of lumens. Then: the larger the number of lumens, the more luminous flux, and the higher the brightness of the lamp.
2. Wavelength
LEDs with the same wavelength have the same color. It is difficult for manufacturers without LED spectrophotometers to produce products with pure color.
3. Color temperature
Color temperature is a unit of measurement that identifies the color of light, expressed in K value. Yellow light is "below 3300k", white light is "above 5300k", and there is an intermediate color "3300k-5300k". Customers can choose a light source with a suitable color temperature according to their personal preferences, application environment, and lighting effects and atmosphere to be created.
4. Leakage current
LED is a unidirectional conductive light-emitting body. If there is a reverse current, it is called leakage current. LEDs with large leakage current have a short lifespan.
5. Antistatic ability
LEDs with strong anti-static ability have a long life and are therefore expensive. Usually LEDs with anti-static greater than 700V can be used for LED outdoor lighting decoration.
6. Life
The key to different qualities is life, which is determined by light decay. Low light decay and long life.
7. Design
Each product will have a different design, and different designs are suitable for different purposes. The reliability design of LED lighting includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, safe use time and other factors.
