Q1: What is the brightness, viewing angle and wavelength of the LED? 

A: Luminous Intensity is equal to the amount of luminous flux emitted into a very small solid angle at a defined angular orientation from the light source. The measurement for luminous intensity is the candela. Symbol is Iv. 
Viewing Angle is the total cone angle in degrees encompassing the central, high luminous intensity portion of the LED beam from the on-axis peak to the off-axis point where the LED intensity is 50% of the on-axis intensity. This off-axis point is known as theta one-half ( 1/2). Two times 1/2 is the LEDs' full viewing angle; however, light is visible beyond the1/2 point.Wavelength is the distance between two points of corresponding phase and is equal to waveform velocity divided by frequency. It defines what color human eyes could recognize.

Q2: What chip do we use for LED display module?

A: The LED chip we use is Taiwan Epistar. 

Q3: What is the warranty of our products? How is the after-sale service?

A: All our product offer two years warranty. And for every batch of goods, we offer spare LEDs and IC or spare module for repair. Also clients could send broken modules, we will repair it for free.
