Hi. I see this used as a description for how "bright" an LED is. But I am wondering, is it the only thing that constitutes to its brightness? I ask because I see 5mm LEDs at 10000mcd, rated at 25ma, but then there are these;
**broken link removed**
some are up to 20000mcd, but can be driven at 350ma. Surely these are more than twice as bright? I know they have a wider viewing angle too, but I wouldn't think that counts toward the luminous intensity, whatever it may be. [/url]
