Very. The light is very even, none of the shadows that a tungsten filament lamp shows.
The LED(s) are very robust, totally unfazed by dropping on concrete.
A standard flashlight bulb may last a few hundred hours, an LED lamp has a rated life of 100,000 hours, that's nearly 10 years of continuous use.
Speaking of continuous use, a couple D cells will provide solid weeks of illumination.
I just purchased a new GE Profile French Door refrigerator that uses LEDs to illuminate the inside. It looked great in the store. I hope I like it as much when it is delivered.
