Lampe Light I is an App which uses the LED flash as a flashlight and turns the device into a Torch with strobe features. The strobe speed can be set via a seekbar which appears once the light is on (after a button click). A click on the button again stops the app. The camera ALWAYS stops when the app goes in background (this is not the case for many such apps!).It works on all devices provided a camera and a led flash are present.
