LEDs have higher output power and bandwidth than lasers.

Explanation:
LEDs emit broad, incoherent light over a wide spectrum and are generally less directional, which limits their peak power density and modulation speed. Lasers produce coherent, highly collimated light with a very narrow spectral width, and they can be driven at much higher modulation speeds. Because of this, lasers typically offer higher bandwidth for modulation and higher power density than LEDs in the same footprint. So the claim that LEDs have higher output power and bandwidth is not correct, though some LEDs can deliver substantial total power and there are special cases.
