Watt LED Torch

LED torch using 8 V source?
I need to make led torch, I have 8 Vdc power source, and 8 pieces of red 1 watt leds. Is it anyhow possible to construct this. I am having problem trying to calculate the value of resistor(s) to use. Can anyone help or explain how the value of resistor is calculated, and if this is possible to build ?
black = 0
brown = 1
red = 2
orange = 3
yellow = 4
green = 5
blue = 6
violet = 7
gray = 8
white = 9
instead of resisters, use diode in reverse biasing mode. it will work
