Firedrops,
It's an RGBA LED, which means that there are four color dice (red, green, blue, and amber) under one single dome. Look on the previous page of pictures to see that the RGBA LED is almost the same size as a regular "single color" LED. It is mounted in the hilt just like any other LED. The difference is that I have three separate circuits (lots of wires!). One to the red die, one, to the blue die, and one to the green/amber dice. I can activate them individually to show you red, or blue, or yellowishgreen, OR I can activate the red and blue dice to give a violet color (since the colors mix). With all four dice activated, the colors mix to white, which is what mimics the clash. So what you are seeing when the color changes is simply turning on switches for a combination of those three circuits. No physical change is needed --it's all in one.
As stated in the video notes, for these tests I'm activating the circuits manually, but ultimately this will be controlled by a CF with power extenders.
Matth,
Sure, I can video and post a Tri-Rebel GGW vs. LE10W RGBA tonight or tomorrow. I can tell you that in real life to my naked eye, the 10W's green die alone is on par with the brightness of a GG. It's *almost* LuxV green brightness, if not dead even (just a difference in the color itself, not the brightness, which throws my eye off).
...Does anyone else have LedEngins they can post pictures of or share experiences with?
