Very Vintage Red LEDs x 20 - non-standard unusual dimensions
These measure closer to 3/16" than the standard 5mm (dimensions below).
No "flat" on the flange, instead a small cut in the flange marks the cathode. The bodies are slightly tapered/conical, not parallel. Their plastic bodies are darker and less transparent than most modern LEDs. Tested: 10 to 20 mA for adequate brightness 1.5 to 1.6 V forward voltage x 15 shorter legs, 4.3 mm body diameter x 5 longer legs, 4.7 mm body diameter I can't find details of older LED standard sizes online (before 3 mm and 5mm sizes), so as for dating them, all I can say is "as old as the hills". I have sample tested a couple, which worked fine. Asking £4.25 for the lot including UK postage by PayPal. Please PM for details. Cheers, Scott

I bet those cost a fortune when they were originally purchased!

Re: Very Vintage Red LEDs x 20 - non-standard unusual dimensions
I could always raise the price to be more "vintage"?!

Re: Very Vintage Red LEDs x 20 - non-standard unusual dimensions
They could be HP. That would explain them fitting to an imperial, rather than metric measurement, and being a darker red. I would like them please.

Re: Very Vintage Red LEDs x 20 - non-standard unusual dimensions
Paypal payment sent, many thanks!
And if they are HP, which I suspect, then they will probably outlast me ! |
