Guys would the 10w led be brighter than than the p4 or luxeon? Im trying to decide if flash on clash is worth it.
It might depend on the color. Not that anyone's measured the various saber configurations with a light-measuring device.
If you're getting a non-mixed color (ones like CG, GB, etc):
The non-FOC is likely going to be a 5W single LED.
The FOC version is likely going to be using a single die of a 4-die (RGBW or RGBA) 10W LedEngin.
So, 5W vs 2.5W on non-mixed colors.
If you're getting a mixed color (SRD, AB, etc):
The non-FOC is likely going to be using 2 dies of a 3-die RGB 5W LedEngin.
The FOC version is likely going to be using 2 dies of a 4-die (RGBW or RGBA) 10W LedEngin.
So, 3.3W vs 5W on mixed colors.
Although if they change what LEDs they use, then all of that will be wrong
And none of this tells you actual brightness in lumens. And then of course there's human eye sensitivity.
In daylight, the human eye is most sensitive to light at a wavelength of 555nm (yellow-green). Think of "optic yellow" tennis/golf balls, and certain emergency vehicles:
