Turn off screen immediately not dim Android

Question

Just to clarify, I KNOW there are ways to DIM the screen but I don't want to do that. I want to simulate a screen timeout but immediately... not using:

        Settings.System.putInt(getContentResolver(), Settings.System
                .SCREEN_BRIGHTNESS, DimScreenValue, 0);

or

        Settings.System.putInt(getContentResolver(),
                Settings.System.SCREEN_OFF_TIMEOUT, iTimerScreenTimeout);

If possible, I want to avoid using Administrative options (screenLockNow)
