What is the advantage of using the 3 LED modules versus the single LED. For instance if I want a green blade, what would be the advantages of either the Green XP-2 or the green green white Tri Cree?
I'm assuming flash on clash? If I don't plan to change colors, what is my better option?
More LEDs will be brighter, but 2 LEDs won't seem twice as bright, and the third will have less of a bump than the second.
Depending on what board you are using will determine the best way to get the color clash you want. green green white will give you a nice white flash and a brighter normal blade. If your board will mix the colors for your flash you could use red + green for a yellow flash, or blue + green for cyan, and of course red+blue+green will be approximately white.
Will there be much difference in run time between a single or tri cree LEDs?
Also, what colors are easiest to see in day and still look 'bright"?
Yes, there can be a significant difference in run time depending on if you use one or two dice.
Green is probably the brightest color to the eye overall.
If you use an NB or a Prizm (both 3.7v), you'll have to wire the two greens in parallel, so you'll have less run time. If you use a CF (7.4v), you can wire them in series, so you won't notice a difference in run time even though it would be just as bright.Quote:

Both blues on will activate the flourescent dye in the photo blade to give you the brightest green that I know how to get without going with Neopixel.
You will always use approximately twice more power for 2 than 1. For a 7.4v battery, the more efficient the driver the greater the difference will be. If you are running two LEDs in parallel on a 3.7v battery, it will be exactly twice what one would have been, plus the power for the board.
