CRI- Color Rendering Index
CRI is another important characteristic of LED light sources. Poor CRI can destroy a beautiful landscape. CRI is a measurement of vibrant and true colors. CRI is measured on a scale from 0-100, with 100 being the best. All lamp sources have different CRI measurements, fluorescents are not very good at 65-70, metal halide lamps are better at 80, halogen lamps are "perfect" at 100. A CRI of 80+ is considered very good within the LED industry. The LED lamps we use are between 82 and 84.
CCT- Correlated Color Temperature
The CCT rating for a lamp is a general "warmth" or "coolness" measurement of its appearance. The lower the "Kelvin" temperature the "warmer" the light, the higher the "Kelvin" temperature the "cooler" the light.A typical halogen MR16 runs from 2800k to 3100k. Our LED lamps are available in 2700k, 3000k, and 5000k.
