The LED's I used in my cluster are 462 nanometer blue, the ones I bought to do my door handles are 472 nanometer blue. Will I be able to see the difference or is 10 nanometers basically nothing.

Probably not too many will be able to help here, but I was just wondering....

 

Nano, a prefix meaning "dwarf" in Greek, also means one billionth. A nanometer is therefore one billionth of a meter. To provide a sense of scale, here are the measurements of some readily visible objects.

• The period at the end of this sentence is almost 500,000 nanometers in diameter.

• A penny is about 19,000,000 nanometers wide.

• A basketball is about 239,506,000 nanometers wide.

• Stanford basketball player Brooke Lopez is about 2,130,000,000 nanometers tall.

 

^ lol. . . .nice

 

I would say no... unless the extra 10 nanometers somehow changes the color. That would be more of a how do LED's work type question though. And I don't know the answer to that.

 

bucky, you must deal with nanometers or something. i deal with ten thousands of a inch everyday and i thought that was small lol.

 

20,000 leagues under the sea?

 

It does change the color, thats the whole point. Different colors have different wavelenghts... thats the whole idea here, I thought it was common knowledge.

Color Wavelength (nm)
Red 780 - 622
Orange 622 - 597
Yellow 597 - 577
Green 577 - 492
Blue 492 - 455
Violet 455 - 390

 

nah google is your friend...

 

I guess not to me. To me, LED's have always just been different colored lights.

Hahaha... anyway, here's what I found.



Using that scale the 462 vs. 472 don't look very different at all. I think you'll be good to go.

 

shucks... I just got the 472s and you can really see a difference. the 462 is much more violet-ey.

 

Nanometer is the wavelength. Wavelength determines color. If it is really only 10nm apart, it will be very hard, if not impossible to distinguish. You are talking Purpleish-blue compared to purpleishh blue.

 

No

I just got the 472's i ordered and compared them to the 462's i've had.


It is very easy to distinguish. Blue vs Indigo almost.

 

Then the diodes arent accurate. A true 10nm difference is hardly distinguishable.
