Bi-color LED lights have some Complexities

By BizLED Bureau

July 14, 2017: When we choose an LED light, we often try to buy one with bi-color, even if it costs us a little more. But according to experts, bi-color LED is not always the best choice.

In a bi-color LED light there is tungsten balance LEDs and daylight balanced LEDs mixed within the same fixture. By adjusting the intensity of each type of emitter, the entire range of color temperature spectrum between the two LED classes is now available to the filmmaker. This way a filmmaker just needs one type of light that they can dial in to match incandescent practicals, or the sun outside, or brands of single-color lights that have color temps that are a bit off, etc.

A bi-color LED light offers multiple color temperatures. Some are switchable between 3200K and 5600K, others give mid-way options such as 4300K, and still others will transition from one end of the spectrum to the other, and offer a variety of Kelvin color temperatures.

However, some LEDs are less color accurate in bi-color mode. After testing the CRI, it is found that it yields lesser results when compared to a good quality LED light, where the high-extended CRI values are a minimum expectation.

It is also found that many bi-color panels have less output at Kelvin values. So here come the need to choose the right LED fixture.

If 5600K (Kelvin) fixtures as daylight, and about . 3200K as Tungsten, and work on the assumption that we’re always trying to color-match environments correctly (for example a daylight lamp in a daylight environment).

A daylight-only fixture will always be brighter than its bi-color counterpart, so you will therefore get more output from a daylight-only fixture than a bi-color one.

You will get the most output from your LED light when it has a fixed temperature fixture.

If you add a corrective gel to the front of a daylight fixture, then it would be a better option than bi-color option.

Many light manufacturers mass-produce colored gels that won’t have the consistency of output and color accuracy of a company that solely specializes in filtration, so be careful.
