About how many feet would the light from a 4000 lumen metal halide light bulb travel when it hits the floor?
About how many feet in a diameter would the light from a 4000 lumen metal halide light bulb travel before it gets too dim to see when it hits the floor? The FLOOR is 12 feet BELOW the light! NOT 12 FEET LONG!
Your question makes no sense.
feet in diameter .. light travel?
If the floor is 12 ft below the light, it travels 12 ft to hit the floor!
