Can you even get indigo LEDs?</p> TnC urn:uuid:07fd0060-a663-1ca6-1613-f4f1c10938d9 2014-10-15T19:41:53-06:00 <p>Yes, those are the ones I was wondering about. Thank you. :)</p> Kamiquasi urn:uuid:9772043f-745c-06e0-f2fc-ba3ed766532e 2014-09-30T14:19:49-06:00 <p>If you&rsquo;re referring to the &ldquo;LED - Basic {color}&rdquo; ones from SparkFun, there shouldn&rsquo;t be any difference. Those are also diffused. Diffused LEDs will emit light in most directions (there&rsquo;s still some directionality to it), whereas non-diffused ones tend to have a very directional emission. These LEDs are also tinted (which they may have meant), meaning that you can identify their color even when the LEDs are off - great for indicators :)</p> TnC urn:uuid:c70f4580-a6f9-2eb7-3185-dae1d853520b 2014-09-30T14:04:21-06:00 <p>Oh that&rsquo;s why a lot of resistor (resister?) color code tutorials say violet instead of purple! I guess, anyways. I wondered about that. But what is the difference between diffused and the basic ones?</p> Customer #229304 urn:uuid:e2c914bf-d1e8-db38-c236-680089273bcd 2014-07-18T03:55:32-06:00 <p>No datasheet link so I measured the forward voltage of each: Red = 1.7 V, Orange = 1.7 V, Yellow = 1.8 V, Green = 1.8 V, Blue = 2.5 V, Purple = 3 V.</p> glasspusher urn:uuid:41847820-55a6-d13b-eadc-af5ff83970d6 2014-07-18T01:58:09-06:00 <p>Uh, they don&rsquo;t say magenta, they say purple. To a lot of folks, purple != magenta. I think if you polled 10 people most of them would say that purple is a synonym for violet.</p> <p>I do agree that violet is the correct description.</p> ryates urn:uuid:78a3abd6-030e-52e0-6d95-0ee5728a6977 2014-06-21T02:20:52-06:00 <p>You&rsquo;re not likely to find purple in a rainbow or anywhere else in the color spectrum since the color purple doesn&rsquo;t actually exist. For an explanation go here: https://www.youtube.com/watch?v=iPPYGJjKVco</p> <p>Also you&rsquo;re own info sheet says those purple LEDs are actually violet 395nm - 400nm, which makes much more since in a rainbow ;-)</p> Gregory W. urn:uuid:debdb01b-a4bb-4e2e-1deb-1470b611c37c 2014-06-20T09:44:09-06:00 <p>Can we get a photo of them all illuminated side by side?</p>
