No........about any LED will do.
Could you teach me any good product ?LEDs have no threshold current.
You'll look for LEDs with high mcd/mA efficiency
You first have to specify "good"Could you teach me any good product ?
Are they surey IF=100uA ?I just tested 4 different colourend LEDs all emit light.
The yellow (very old) ones are barely visible.
(I don´t know if this is by age, by internal circuitry, by technology or by color)
But all the others are very good visible.
Stanley FHR1105P-TRPerhaps your particular LED is not bright enough at 10-20mA?
Try a different one.
We still don´t know waht "ggod" means for you.Is there more good LED ?
Is there more good LED ?
10Volts ?100uA --> if it´s not hard for me to use a 10V supply and a 100k resistor,
then it shouldn´t be hard for you to do a similar test.
candela unit is already weighted with eye sensitivity function. Different LED colors with same cd should give same intensity impression.The candela definition is both confusing and ambiguous.
What has a test method to do with product design?10Volts ?
Do you have actual experience of electric product design ?
10Volts ?

I've seen modern LEDs with even higher mcd/mA, but not in 0402 package as apparently preferred by pancho_hideboo.you may please check ...
