LED versus regular flashlight bulb...more strudy?

LED flashlights get at least 5 times as much light from the batteries. They are inherently twice as bright because all the light goes forward. Reflectors can save a portion of the backward light from a filament but not a high percentage. Loss in the glass lens is probably only 10% and the lens can focus to a narrow beam close to the diffraction limit for the tiny size of the LED, which is spectacular.

The flashlights I linked earlier can handle drops on the floor most of the time but occasionally they die. Possibly as frequently as incandescents.
