Lighting apparatus

1. A lighting apparatus comprising:

a housing having a handle portion:

a light intensity control component;

a focus control component; and

a light source accommodation component;

wherein the lighting apparatus is configured to be handheld with a single hand and wherein the light intensity control component and the focus control components are disposed on the housing so that when the handle portion is gripped by a user's hand, the user's fingers of that same hand are within reach of both the light intensity control component and the focus control components; and

wherein the lighting apparatus is configured to have a power source integral with or attached to the handle portion.

2. The lighting apparatus of claim 1 further comprising a beam angle control component.

3. The lighting apparatus of claim 1 further comprising:

an accessory mounting system configured to mount light modifying components to the lighting apparatus.

4. The lighting apparatus of claim 1 wherein the apparatus, including, the light intensity control component and the focus control component is configured for the single hand to be either a user's right or left hand.

5. The lighting apparatus of claim 1 further comprising an adjustable light blocking component.

6. The lighting apparatus of claim 5 wherein the adjustable light blocking component comprises two or more barn doors.

7. The lighting apparatus of claim 1 wherein the power source is positioned below the handle and the handle is disposed in a direction within 15° of the normal to the light beam direction.

8. The lighting apparatus of claim 1 wherein the power supply is positioned below the handle and the handle is disposed in a direction between 5°-10° of the normal to the light beam direction.

9. The lighting apparatus of claim 1 wherein the center of gravity of the apparatus is at or near the handle.

10. The lighting apparatus of claim 1 wherein the light beam is focusable from a spot light to a flood light.

11. The lighting apparatus of claim 1 wherein the light source is a light emitting diode.

12. The lighting apparatus of claim 1 wherein the light source accommodation component contains it plurality of light emitting diodes, and the apparatus includes a light source adjustment component to activate all of the light emitting diodes or one or more portions of the light emitting diodes.

13. The lighting apparatus of claim 1 wherein the light intensity component creates a dimmer function that follows a tapered dimming curve.

14. The lighting apparatus of claim 1 wherein the light intensity component creates a dimmer function having a linear gradation.

15. The lighting apparatus of claim 1 comprising an aspherical lens.

16. The lighting apparatus of claim 1 further comprising, a Fresnel lens.

17. A kit comprising a lighting apparatus according to claim 1 and;

a power source;

a recharger; and

a plurality of light modifying components.

18. A lighting apparatus comprising:

a housing having a handle portion;

at least one light source capable of producing a light beam;

wherein the handle is disposed in a direction within 15° of the normal to the light beam direction;

a light source accommodation component, wherein the at least one light source is removably received within the light source accommodation component;

a light intensity trigger control component functionally connected to at least one light source to dim the at least one light source, wherein the light intensity trigger control component is positioned along the handle portion's longitudinal center line so as to be accessible for control by a single hand and to be accessible by either the right or left hand;

a focus control component functionally connected to at least one light source to focus the light beam from a spot light to a flood light;

an automatic shut-off component;

wherein the power source is positionable below the handle; and

wherein the at least one light source is a light emitting diode.
