Q: Infinity and Arc colours

Colour wise, is CMG Infinity's blue/green similar to Arc-AAA's turquoise?
Which is the brightest Infinity: green or blue/green?
Which is the brightest Arc: green or turquoise?
TIA

The turquoise Arc is a more greeny colour than the blue-green Infinity.


Which is the brightest Infinity: green or blue/green?

I havn`t seen them side by side for a little while but from memory I`d say the blue-green is brighter. Plus as it has a broader emitted spectrum(greens and blues, instead of just greens)- meaning that more colours can be distinguished and in general it will appear brighter.

I don`t have a green Arc yet but I think the Turquoise one would be brightest- mainly for the reasons I mentioned above. I think the green LED used in the Arc has a higher official candela rating (~10000 as opposed to ~7000) but since it emits mainly just grene light, it may appear dimmer. Also the human eye is most sensitive to light with a wavelength that is very close to the Turquoise LED colour.

Hey, they have a luminous intensity of 10000 cd! That's really bright!. OK, serious:

Even when one LED is rated at 10cd and the other at 7cd, it does not say too much. These values are for the nominal current (usually 20mA). And the Arc AAA runs the LED at a higher current than the Infinity. This will also shift the colour a little bit.

If you have two lights with the same luminous intensity (you call it 'candela rating'), they are equally bright. Even if they have a different colour. Actually that's the trick. Radiant intensity will be different, but brightness is not.

I have both the green Infinity, and the blue green Infinity. Without instruments, I don't think you couls tell the difference in brightness. Both are *much* brighter than the white one. The green Infinity has a fairly 'focused' beam. However the color distortion of the green one is much higher than for the blue green Infinity. I greatly prefer the blue green to the green one; the blue green color is 'lighter' than green, so it may look brighter, while instruments may not show it as being brighter. In any event, I'd recommend the blue green over the green Infinity; I think you will prefer it.

Thanks Chris and Gandalf for those descriptions.
Gandalf,-would you say the turq. Infinity beam is more "focused" than say, the Arc-AAA's beam?
(I'm making yet another lightstick, and really like the super-longevity of the Infinity elements).

p.s.-wish I could figure out how to get just the turq. element by itself, as I've already got amber and white ones as it is.
