What is the difference between RGB, TrI LED and HEX LED Lighting fixtures?

---

The next generation of lighting fixtures for stage, theater and nightclubs is already here. You see them all over the place, like in flashlights, car signal and effects lighting as well as headlights, and you see them almost everywhere lighting up everything. LED stands for “Light Emitting Diode” and is actually a diode that only permits an electrical current to pass through it in only 1 direction, it has uses in may different applications, however in this application we are talking about the newest generation of LED’s that are super bright, very powerful and are used to emit vast amounts of light for theater, stage, nightclubs and tons of other lighting applications.

Light travels to the human eye in a wavelength (nanometers) when we see the wavelength of light, we see colors, The main basic colors are “Blue” with a range from 525 - 430 nm, Red, 600 - 623nm and Green, 570 - 555nm, as you would look at these differences in the wavelength in blue for example the light color would change it’s color hue from a aqua-green-blue to a ultra-blue and the same with the other colors from red to green. In a LED light fixture there is a array or cluster of these LEDs in different formats, RGB (Red, Green- Blue) This LEDS use a color mixing logic control system to changed the intensity of each LED’s to mix rainbow of different colors, however newer LED lighting fixtures have more LED color choices and that gives you even more lighting control.

The first wave of LED light fixtures had a LED array of RGB Clusters, the lights were designed with groups of RED, BLUE and GREEN LEDS displayed out in different patterns depending on how the manufacture designed the light and when you wanted to mix colors the LED would emits different intensities and make color, for example if you mixed certain amounts of RED and BLUE you get different shades of purple, if you mix RED and GREEN you get different shads of oranges and yellows (notice that in light mixing Green takes the place of a yellow LED) - this is how you can use a RGB light to mix different shades of colors. the only disadvantage is a RGB light can not produce white light, however they can produce a bright kind of bluish white, but not a real white. To overcome this problem there is a complete array of white only LED lights available to fill this gap. These lights have different mixtures of LEDs in the white / amber color range and that will mix different shades of white (White LED sources are measured in Kelvin and not in nanometers.)

Now we move into TRI LED light fixtures - TRI LED’s take color mixing to a new level with brighter RGB LED’s that and fused into one LED, so instead of a cluster of RGB LED’s you have one LED with all three RGB LEDS built into one single LED. The color mixing is more precise and you lose a lot of color artifacts and color shadow problems for stage and theatrical lighting. Instead of clusters of LED’s TRI LED’s have groups of LEDS. If the light is designed for more advanced color mixing it will have RGBW, RGBA, RGBAW and HEX LED’s offer RGBWA+UV+ - in these examples the addition ow a “W” means a white LED, an “A” means an amber LED and the UV means the a ultra violate LED has been added to give the light the most color mixing opportunities available. These new RGBWA light fixtures can not only produce almost any color you can imagine, they can also produce different shades of whites and pastels - Light fixtures with HEX LED’s have all the LED’s fused into one LED like TRI LED’s However these have all six, hence the HEX designation, These new HEX LED light fixtures can produce everything from deep saturated colors, hues or shades of whites, pastels and UV black light as well, The main differences in these newer LED light fixtures is size, power and beam angles.
