While the original Cree no longer exists, their tradition of producing top-quality LED chips remains under the Smart Global Holdings and Cree LED banner.
Customers use them in video screens, outdoor lighting, emergency lighting, flashlights, industrial lighting, and vehicles. You can also use them in general lighting. Cree LEDs are efficient, deliver high lumen density, and are very reliable.

Cree LEDs: What are they?
Advantages of Using Cree LEDs

What Are The Advantages of Using Cree LEDs?

Efficiency: To be fair, most LEDs are more efficient than any other light source. However, Cree LEDs are generally more efficient because they use innovative technology of their own design. For instance, the 4Flow-based LED bulbs perform and incandescent light bulbs while lasting longer and using less power.

Stringent quality and performance verifications: An accredited independent third-party laboratory verifies the performance of all Cree products. This ensures that there are no conflicts of interest.

Wie funktioniert eine Cree-LED?

Cree LEDs work just as any semiconductor does.
Current flows through a conductor that carries it to the diode. The diode then emits photons, which appear to us as light. What makes Cree’s LED technology different is the materials and approach to developing their LED chips. A good example of this is their CPW5 Z-Rec high-power silicon carbide (SiC) Schottky diodes.
