Glad Menna's going to test. Did not catch that fact.
In the early days of bright whites, before the smaller packaging I wanted to make some led lights for my camper..
I tried to do it strictly with resistor biasing...
The % tolerance of the leds...18ma to 23ma v/s the swing of my camper battery 12-14.6 was just too close to the edge of the upper current tolerances of the led's if I wanted the led's to be bright (Lumens).
If I adjusted the bias to keep the upper current low, say 21ma then when the battery voltage was around 12vdc the led's were too dim.
I played with regulators, did it that way but I did not like doing it
that way so I quit messing around with them...
Then about 2 years later the whole LED thing exploded with the advent of the little buck regulator...Wow! Love that .2ma v/s 1.2+amps.
