Alright so mcd, or millicandela, is pretty much the intensity of the light emitted from an LED.
I'm making a UV meter with an LM3916...I know it has some comparators and some other circuitry inside, but would it be smart enough to adjust the output so the intensities are the same? The reason I ask is because I'm going to have green, yellow, red, (and maybe a blue) LED. I want them all to be the same brightness...and not have it like...green green green YELLOW! YELLOW! red red.
Assuming no...
Maybe this is subjective. I want LEDs that are bright enough to be clearly seen a dark room...but I don't want to light up the room with them, if you know what I mean. There's going to be a total of 20 LEDs. I don't want to go blind if they all get lit.
100mcd? 1,000mcd? 10,000mcd?
Also, how big is the difference between say an 80mcd LED and a 60mcd LED? So if I can't match the LEDs perfectly, how far away can they be from each other without being noticeably different intensities?
Thank you very much.
