Since Fire Orange (FO) is created from a single LED (or three same color LEDs when Tri-Cree), the color will only dim as your batteries lose power. Mixed LED colors are created by illuminating 2 LEDs with varied resistance, like the Violet Amethyst you mentioned is made by mixing Red and Blue. However, when the batteries start to lose power, the LED with the highest power requirements and highest resistance will fade first because the electricity is literally taking the path of least resistance. In the case of VA, the blue is both higher power and has a resistor, so as the batteries drain, VA will eventually just be Red.
A way to counter this is to get the Li-Ion setup with a Buckpuck. I'm not sure how it works, but from experience, it maintains a constant flow of power for maximum effect. When the batteries no longer how juice to maintain, the saber shuts off. The pro: your saber will look good for the duration. The con: you won't have power for as long. I have Li-Ion and sound in all my large sabers. When I go to cons, I prefer using sabers that have the V4 sound so I can mute the sound. This allows for nice and bright all day. Continuous use lasts about 1.5h (w/sound about .5h)
Hope this answers your question
It sure does - I did understand prior that multiple-LED driven colors will feed the most power to the most power-hungry colors. I appreciate the info. I guess I didnt realize that with the V4 sound board that you could disable the sound which probably saves a lot of juice. Hmmmm. Guess Ill have to go with the V4/BuckPuck arrangement on my next saber!
THANKS.
BTW - thats quite an arsenal you have listed. Nice collection!!!!
