The traditional fluorescent light-emitting efficiency is about 55-80lm / W, while the LED tube lights luminous efficiency of 100lm / W or more. Recently the LED lamp luminous efficiency is 130 lm / W, and the future will continue to improve. Difference between the two has now been nearly doubled, and may be three times in the coming days.
The lighting is efficient, because the fluorescent light is 360 degrees, and in the opposite direction the light would not be useful. So usually a white fluorescent lamp, the reverse can be a considerable part of the light reflected back, in general, the efficiency of fluorescent lamps only about 70%, while LED tube lights are 120 degrees, so all light is the effective optical. Although sometimes you may feel light-emitting angle of 120 degrees a little narrow, but in most cases is adequate. Moreover, this perspective is the light can be adjusted as needed.
