Cool White (6000° Kelvin) is the color of bright sunlight, on a wintry day. It emphasizes blues, lavenders and turquiose hues stronger than warm colors, but it has a tendency to make Caucasian skin look pasty. Due to the nature of LEDs, Cool White has the highest efficacy (Lumens/Watt) of all the color options offered.

The type of light a tungsten bulb is known for putting out is usually thought of as "Warm White". The Aleph 2 version of this is rated at 3000°K. It compliments skin tones, making food, clothing, and decor look more normal for "inside use".

This is usually ordered as part of a Red/Green/Blue combination to mix colors, but might be added to a series of white choices to be able to make tints of pink, especially suitable for lighting a food service or restaurant environment.

This is usually ordered as part of a Red/Green/Blue combination to mix colors. It also might be desirable for horticulture or landscape lighting purposes as a solo entity.

This is usually ordered as part of a Red/Green/Blue combination to mix colors. It also might be something requested in lighting a fountain or pool by itself.

Many users enjoy having a flexible arrangement that allows them to choose the desired color temperature. This typically means mixing Cool White with Warm White. That gives them a range of options that are all nominally white, but have subtle differences, allowing for different moods and a hint of place or time of day shifting.

The very best way to view colorful objects is under a light which has a high Color Rendering Index (CRI). ENTTEC's High CRI option features LEDs with 85 CRI such as the CREE XPG. That translates to a rich and faithful reproduction of colors, while still maintaining great light output (high efficacy).

While the basic CTA strips give a range of white tints, the best looking mixture of different color temperatures will be based on LEDs that start off with a higher Color Rendering Index. These High CRI adjustable LEDs combine the flexible arrangement of CTA and the specification grade superior performance of top LED components to achieve a mixed white suitable for photography, film/video, or discerning retail environments.
