LED Question Answered

Picture of

I am putting a wire under my porch with LED's placed periodically along the length of it. It will light up a small garden just below/behind the porch, about 2 feet below the bottom of the porch. I am going for the effect seen in the attached picture.

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.

Thank You!

I would recommend just buying a big bag of led's from ebay that fits your budget. You can add/remove the amount of leds from your string as you feel fit. It saves the hassle.

I would say 50 MCD is fine for garden accent lighting at 2 feet.
