Fantastic pictures. Thank you for sharing! And I agree with the Capt., it would be even more awesome to have some pictures of the LEDs on. I don't understand, for example, why a rectangular shape would have better diffusion than one that's mathematically more even. Is it because there seems to be a thinner shell overall on the 2×3×4㎜ LEDs? In addition, the hollowed-out, fan-shaped cavity where the diode resides also seems smaller on the rectangular LED. Perhaps this makes a difference, as well.
These pictures opened my eyes.
Because of rectangular edges acting as mirrors in some way and deflecting some of the light. Spherical top LEDs have the worst viewing angle of the 3 for water clear varieties. Just have a look at LED documentations sheets.Well, I'm sold. Thank you for the explanation.
Thanks for these pictures. I just ordered some 2x3x4mm rectangular LEDs and it sounds like I made a good choice.

Where did you order your LED's?

Love the thread, missed it earlier somehow.
I too highly recommend the 2x3x4mm LEDs. THe ebay seller colorfulpace is a great place to get them for cheap.
Just to elaborate a bit on naokira's uncommon LED shape: they're referred to as 1.8 mm LEDs.
The specs (view angle, light intensity) are generally the same as their 3mm equivalents, and they're not more expensive, so if you can find them in the flavor you want they're a good choice too.

Has anyone actually tried this out in practice? I just want to know whether people have real experiences with the 1.8mm LEDs. (Am always worried that something will get burnt out or some disaster will occur.)
I'm not sure if you are directly answering to my post, or if I messed up somewhere, but I was talking about LEDs being damaged by overvoltage, not overcurrent ;)

LEDs are constant voltage devices.
I looked into it some time ago.
Another necrobump with a question, does anyone have experience using UV LED as alternative for Purple LED?
Wow I never knew this thread existed. Super helpful.
I read somewhere that certain LED shapes get in the way of DSA keycaps, are there any shapes/types of LEDs I should be aware of when using low profile caps?
I believe 1.8mm is fine for all.
2*3*4 might need to be sanded but I think it's okay as well. It's the keycaps with a cross supporting the stem on the inside that have clearance issues I believe.
3mm might be too tall, though SP does make windowed DSA caps so it might be fine.
Thanks!I looked into it some time ago.

Based on the spectral emission, just get a UV LED. Most UV LED and purple LED are cross-listed as eachother, and looking at the datasheets: about the same.
don't worry about the LED killing your eyes: apparently it's near-visible UV, and (probably) won't cause harm.

3mm flanged, 3mm flangeless, and two 1.8mm LEDs.
It's pretty much the smallest non-SMD LED you can mount on a Cherry MX switch:Show Image(https://dl.dropboxusercontent.com/u/1042331/Keyboard/LED%20stuff/P6245232.JPG)

1.2mm LED

Question: Is the uniformity or diffusion of light about the same between 1.8mm and 2x3x4s? If so, I guess the main benefit of 1,8mm is the clearance, correct?
This thread should be stickied, IMHO. Great information for anyone working with Cherry MX switch boards. Should I PM Soarer to request this?
