6 . The modular task lighting system of claim 1 , wherein the second clamp is configured as a slidable carriage that eliminates sag inherent in articulated arms by providing independent linear translation along the second post.

7 . The modular task lighting system of claim 1 , wherein the base is a C-shaped clamp base comprising a resilient grip layer and an edge grip sized to engage a music desk cross-rail on a grand piano for directing light toward sheet music.

8 . The modular task lighting system of claim 1 , wherein the upper assembly folds compactly at the first clamp when detached from the base enabling portability.

9 . The modular task lighting system of claim 1 , wherein the base is a flat, weighted pedestal base comprising multiple post sleeves, configured to support multiple upper assemblies on a table surface, such as in a library setting, allowing patrons to connect personal light planks or illuminating devices.

10 . The portable task lighting system of claim 1 , wherein the base is a C-clamp and configured to attach to a piano music desk rail using compressive engagement.

11 . A method of assembling a modular task lighting system comprising:

providing an interchangeable base with a post sleeve;

removably inserting a first post into the post sleeve;

adjustably clamping a second post to the first post using a first clamp to enable vertical translation and rotation;

slidably mounting a second clamp on the second post for lateral translation;

coupling a multi-axis linkage to the second clamp, the multi-axis linkage including a vertical pivot, articulation joint, and ball-and-socket;

detachably coupling a light plank with an illuminating device to the multi-axis linkage via a quick-connect plate; and

wherein the method enables tool-less reconfiguration, detachment of an upper assembly for folding, and interchange of the base.

12 . The method of claim 11 , further comprising:

loosening the first clamp to allow vertical translation of the second post along the first post and rotation of the second post about the vertical axis of the first post;

positioning the second post at a desired height and azimuthal orientation;

tightening the first clamp to lock the height and rotation;

loosening the tightening knob of the second clamp;

sliding the second clamp along the second post to a selected lateral position; and

tightening the tightening knob of the second clamp to lock the lateral position without introducing vertical deflection under load.

13 . The method of claim 11 , further comprising adjusting the illuminating device in three planes by:

loosening the knob of the secondary articulation joint to allow tilt and rotation adjustment;

loosening the ball-and-socket joint to allow pitch and yaw adjustment;

aiming the light plank to achieve glare-free illumination on a target surface; and

tightening the knob and ball-and-socket joint to maintain the selected orientation.

14 . The method of claim 11 , further comprising detaching the upper assembly from the base by removing the first post from the post sleeve of the base enabling:

folding the upper assembly compactly at the first clamp;

reconfiguring the upper assembly with a different interchangeable base selected from the group consisting of a weighted pedestal base, a C-shaped clamp base with resilient grip layer, a wall-mount base, and a table bar base with edge grips; and

re-attaching the upper assembly to the selected different base without tools.

15 . The method of claim 11 , further comprising:

detaching the light plank from the multi-axis linkage via the quick-connect plate;

using the detached light plank as a standalone portable illuminating device; and

re-attaching the light plank to the multi-axis linkage or to a different multi-axis linkage of another lighting system.

16 . The method of claim 11 , wherein the base is a C-shaped clamp base comprising a resilient grip layer, and the method further comprises:

positioning the C-shaped clamp base onto an edge of a table or onto a music desk cross-rail of a grand piano;
