lower end of upper mast 6 telescopingly connected within a middle mast member 8 and the lower end of middle mast 8 telescopingly connected within a lower mast member 10 it is contemplated for middle mast member 8 to be upwardly telescoping from lower mast member 10 and for upper mast member 6 to be upwardly telescoping from middle mast member 8 so that boom arm 12 can be raised from a height of approximately thirty two inches to a height of approximately ninety inches fig1 further shows a first quick release clamping device 30 connected between middle mast member 8 and lower mast member 10 and a second quick release clamping device 30 connected between upper mast member 6 and middle mast member 8 each quick release clamping device 30 allows the next adjacent upper mast component either middle mast member 8 or upper mast member 6 to be locked in various extended positions relative to the next lower mast component either lower mast member 10 or middle mast member 8 respectively it is contemplated for the knobs on quick release clamping devices 30 to be sufficiently large for easy use by an operator 39 s hand not shown although the materials from which upper mast member 6 middle mast member 8 and lower mast member 10 are made are not critical such materials must be sufficiently strong to support the weight of boom arm 12 and light fixture 14 yet sufficiently light in weight for lighting device 2 to be easily handled by most operators not shown in the preferred embodiment shown in fig1.
