The brightness level of a 12W LED equivalent bulb is typically around 800 lumens, which is similar to a 60W incandescent bulb.
6(2w + 1)
It is 12w = 48 or w = 4.
fluorescents are about 5x as efficientso a 12W will give about as much light
39 + 12w = 1039 -10 = -12w29 = -12ww = -12/29 = -0.413
20
It is 12w.
The product of w and 12 is 12w.
