CCT indicates the hue and tone of white light emitted from a specific bulb or fixture. It’s measured in Kelvins (K), which is similar to degrees in Celsius. Different temperatures on the Kelvin scale represent different colors. For example, light at 2000K-3500K looks more orange/yellow and is called ultra warm or warm white, and as temperature increases in Kelvins, color changes to more of a “paper white” known as natural or neutral white (between 3500K and 5100K) and finally into a bluish-white known as cool white (5100K+).
As a light source’s color temperature increases, brightness often increases. While shopping for LED lights, pay close attention to the color temperatures that are available for any one bulb or fixture. Choosing a warm white bulb with a color temperature around 3000K might mean sacrificing some brightness. Whereas, if you choose the natural white version, it’s likely that it will have a higher output.

In order to understand nanometers, you must first understand the electromagnetic spectrum and wavelengths. The electromagnetic spectrum is the entire range of invisible and visible light, and a wavelength is the distance between peaks of light waves. Wavelengths are measured in nanometers, which are simply units of length that indicate colors of light within the spectrum. Nanometers will tell you how red, green, yellow, purple, etc. a light source really is. These measurements start lower at ultraviolet and increase from green to blue, yellow, orange, and then red. The wavelength of a colored light can be found in the light’s specifications table.
MR16 beam angle in degrees (left to right): 36, 24, 15
Fixtures or bulbs that emit wide beams, such as BR LED bulbs for can lights are great for areas that require a lot of light, such as basements, kitchens, or living rooms. Narrow beam angles like those from can lights with MR LED bulbs are best for highlighting decor or small areas. Globe bulbs, such as G30 LED vanity bulbs, have 360-degree beam angles, which means that they throw light in all directions. Globe bulbs are the perfect choice for centralized light fixtures.
