What is CCT ? |
 |
Correlated Color Temperature (CCT) is a characteristic of visible light that has important applications in lighting. The color temperature of a light source is determined by comparing its hue with a theoretical, heated black-body radiator.
The Kelvin temperature at which the heated black-body radiator matches the hue of the light source is that source’s color temperature. |

What is CRI ? |
|
Color Rendering Index (CRI) is a measure of the ability of a light source to reproduce the colors of various objects being lit by the source. It is a mathematical formula describing how well a light source's illumination compares to the illumination provided by a reference source. The index provides a number up to 100 for ideal light. |

What is forward voltage (Vf) ? |
|
Forward voltage (Vf) is the voltage across a diode for a given forward current. |

What is High Power LED ? |
|
High Power LED refers to a type of LED with a driving current of 350mA and above. Baytek Opto design and manufacture high power LED ranging from 1 Watt to 10 Watt. |

What is LED ? |
|
A lighting-emitting diode (LED) is a semiconductor device that emits incoherent Narrow-spectrum light when electrically biased in the forward direction of p-n junction. The color of the emitted light depends on the composition of the semiconducting material used, and can be infrared, visible, or near-ultraviolet. |

What is Lumens ? |
|
Lumens in an international unit that refers to the amount of light that a light source produces. For example, a 60 Watt incandescent lamp provides about 800 lumens. A1 Watt Baytek Opto LED provides 85 lumens and up. |

What is Solid State Lighting (SSL) ? |
|
Solid State Lighting (SSL) refers to a type of lighting that utilizes LEDs as sources of illumination rather than electrical filaments or gas. The term “solid state” refers to the fact that light in an LED is emitted from a solid object – a block of semiconductor – rather than from a vacuum or gas tube, as is the case in traditional light sources. |

What is wavelength (λd) ? |
|
Light could be split into many colors. The colors produced by light are arranged in a precise array or spectrum. The order of color is constant, and each color has
a unique signature identifying its location in location in the spectrum. The signature of color is the wavelength of light. |
