Why we cant use normal light for surgery (weaknesses)

1) Because normal light has poly-chromatic light that contains light with more than one wavelength
2) low directionality (broad width)

Why we use light at the street instead of laser?

# data[].attributes.body
1) Emit lower intensity (monochromatic light)
2) broad spectrum of light(variety of wavelength)
3) puts out light in every direction at the same time
4)more safety compare to laser
