Here are some resistances for (very) roughly similar brightnesses (to my eye) from the standard Tayda LEDs and the ones from AliExpress:
| LED vendor | type | color | SKU | V | R |
|---|---|---|---|---|---|
| Tayda | diffused | green | A-1553 | 5 | 470 |
| " | " | " | " | 12 | 2.2k |
| " | " | red | A-1554 | 5 | 3.3k |
| " | " | " | " | 12 | 15k |
| AliExpress YuanQi AI | fog | green | - | 5 | 39k |
| " | " | " | - | 12 | 150k |
| " | " | red | - | 5 | 6.8k |
| " | " | " | - | 12 | 22k |
I used the AE LEDs on my clock module. The supply is 5 V, I used 6.8k for the red and 39k for the green, and I think that looks good.
Extending the legs to reach the jacks PCB is a pain, though, and I’m considering building a module that would use 11 of them. Ugh. I’ve found what look like similar LEDs but with longer legs from a Hong Kong vendor on eBay:
I have these on the way.
