REAL OR FAKE CREE LED?

Ever wonder if your LED is a Real Cree LED?  We have found that with LED's becoming more and more popular, the market is being flooded with the FAKE kind.  Here is some information on how to tell if your LED is a Cree LED or not.
It’s a well-known fact that Cree LED Chips have the best performances in output, lifespan, stability, etc.
It's simple to recognize if your LED lights are using Cree LED chips or not.
Cree's cathode design incorporates a square with parallel lines dividing the surrounded area into equal rectangles. This creates a negative "plane" instead of a point but is also very helpful in identifying the model of LED.
You will see what the following means:
  • XRC / XPC - 2 rectangles
  • XRE / XPE - 3 rectangles (some XR-E have a 0.9x0.9mm die instead of the usual 1.0x1.0mm found in this series)
  • XPG - 4 rectangles
  • XML - 6 rectangles

Below are several ways to identify your LED chips:
  1. Use a microscope (professional one or simplified one, both are ok) to check the cathode, Cree’s silicon carbide cathode looks very special, you can easily distinguish according to above description.
  2. Cree’s Optical lens is in high pellucidity and refractivity, it’s with a very smooth and glossy surface.
  3. Cree LED chips are well-made with very fine handcrafted, tidy and clean soldering joints.

Fake Cree LED chips:
Some chips look the similar type and shape as the Cree chips, but if you check them with a microscope you can easily find the cathode is totally different.  They are fake Cree chips.
