I have been looking online (esp DigiKey) for LED's and they give brightness ratings in millicandela, but I cannot for the life of me find a reference as to how bright 1mcd is vs 1000mcd (1 candela). I am looking for something that will give a mild, path-lighting like effect, but won't be so dim that it can only be seen when all other lights (i.e. the light above the porch) are off.
These will only be on at night, and will most likely be a warm-white color. I will most likely rough-up the surface of the lights to make the beam more diffuse.
