    Default Cyan luxeon star question

    I just installed my first cyan colored star and it looks green. Is this the correct color or was it somehow labeled wrong?

    Lumiled's Cyan's are all over the spectrum! [img]/ubbthreads/images/graemlins/frown.gif[/img] I have seen cyan, green, blue green and an orange/green???!?!! Unless you get a good color bin, you won't have cyan.

    - Don

    PS. I don't know what bin letter refers to the *real* cyan.

    orange green?

    i can't imagine such a color...

    i've had very limited experience with cyans, but the ones i used were quite cyanish...

    Are you overdriving/underdriving it? It could be that or the Luxeon Lottery...

    I bought cyan luxeon from Inretech and i got greenish luxeon, instead of blue green. Also, I bought turquoise ARC aaa from Vicomptel and got the same color with the greenish luxeon from inretech. I guess it is still the same ol' luck of draw

    This one is very green and I'll just assume it is due to the luxeon lottery. I put it in my Blaster II from Elektro Lumens. This seems to be a very bright led, or my eyes are just very sensitive to this color. I want it to get dark so I can try it outside, but it appears that it will have incredible throw.

    Cyan's VERY radiant (reflective) at night. Side by side, a 5W Cyan HD will look brighter than a 5W White HD... Eye's perception of green/blue spectrum's greater than white when at night.

    I set this one up for using when canoeing at night hoping that I would see things in the river ahead of me quicker than with white. I don't know though if my eyes can handle this color for long periods of time. I'll be testing it along with several others soon, so I'll get an idea of how it works in comparison to white.

    I see a lot of beamshots of cyan and they all look like the blue luxeon (not royal blue). Like whiteish pale blue. Is this the luxeon's fault due to a poor bin rating or the way the camera's perceive the color? (a few beamshots I've seen that looked correct though)

    I believe the correct color is supposed to be something like the green light on a traffic signal.

    When you first look at the Luxeon CYAN, it does appear "Green"; but when you compare it side by side with the Luxeon GREEN, you will see that it is indeed CYAN (Greenish-Blue)

    Its just like when you turn on a normal flashlight and your eyes register the light as "White" and then you turn on a White LED and then your eyes register the light from the flashlight as "Brown"

    Mike,

    I just ordered one of your cyan adapters via the website. Any idea when and how it might ship (it said USPS, but no reference to 1st Class, Priority, etc.)??

    Thanks,
    Danny

    FalconFX's picture looks like cyan. Looks acurate to me. I can tell that a pure green would look different, but this doesn't look like blue either. Looks perfect color to me. I like that color. Imagine flooding someones house with that color. They'd think that aliens were going to abduct them! [img]/ubbthreads/images/graemlins/grin.gif[/img]

    As for the question about the adapter shipment

    The adapters are in stock, and it should ship out Monday afternoon, USPS - you should have it in 3-4 days
