The ornamental design for a hanging lightfixture, as shown and described.
FIG. 1 is a perspective view of a hanging light fixture illustrating my new invention;
FIG. 2 is a front elevational view of the hanging light fixture;
FIG. 3 is a rear elevational view of the hanging light fixture;
FIG. 4 is a top plan view of the hanging light fixture; and,
FIG. 5 is a bottom plan view of the hanging light fixture.
In the figures, the hanging light fixture is substantially radially symmetrical. Thus, left and right views are omitted as being identical to the front view. Additionally, the broken lines represent environmental structure which forms no part of the claim.
