Thanks. Looking for yellow LEDs, Any size.hi navy,
Please give more information for the LED type, current rating, colour, voltage rating etc...

Ok. Thanks so much. All I’m hoping to do is power about 16 LEDs through my Parallax basic stamp project board..The really bright ones run closer to 300mA and around 3.5 volts . Chek the offerings of Digikey and Newark.
BUT you will need a much more detailed description of what you want. My friend has LED high beams on his car, they run on 12 volts and draw many amps. THOSE are super bright.
Great. Thanks.OK, now I understand the size a bit more. OK, DigiKey has sold high brightness LEDs described exactly that way. They may still sell them. So check their web site catalog.
the string of 200 mA LEDs that I played with is uncomfortably bright. , so you are quite correct.I have seen ads for large LEDs rated for 700mA but I have never seen one. if a 20mA LED is Very Bright then a 700mA one would blind me.
Of course they are dimmed. It is using Pulse Width Modulation. Each LED is "on for a brief moment".Strobing LEDs from left to right (or right to left, doesn't matter) so that only one LED is on for a brief moment, then the next, then the next, then the next and so on. Sweep them fast enough and they will all appear to be on.
I've built chase lights using LED's in the past. Sweep them fast enough and they all appear to be on at the same time. And they don't diminish in brightness.
