Low-profile light fixture joints reduce the appearance of a seam between joined ends of one or more polymeric panels at a connection interface. The joint is formed between a first end of a polymeric panel and a second end of the same or a separate polymeric panel. Each end has an upper edge portion, a lower edge portion opposite the upper edge portion, a flange extending between the upper edge portion and the lower edge portion, and a notch disposed between the flange and one or more of the lower edge portion or the upper edge portion. The notch enables the upper and/or lower edge portions to present straight edges at the connection interface, the joined straight edges forming a butt seam at the connection interface, while the flanges present rounded edges at the connection interface, the joined rounded edges forming a tucked seam at the connection interface.

1. A method of forming a low-profile light fixture joint, comprising: providing a first end of a polymeric panel and a second end of a polymeric panel at a connection interface, the first end and the second end each comprising:an upper edge portion;a lower edge portion opposite the upper edge portion;a flange extending inwardly relative to an outer surface of the polymeric panel, between the upper edge portion and the lower edge portion, wherein each flange comprises a lower tapered edge adjacent to the lower edge portion; anda notch disposed between the flange and the lower edge portion;wherein: the lower edge portion of the first end and the lower edge portion of the second end each present a straight edge at the connection interface;the flange of the first end and the flange of the second end each presenting a rounded edge at the connection interface;joining the straight edge of the lower edge portion of the first end and the straight edge of the lower edge portion of the second end to form a butt seam at the connection interface; andjoining the rounded edge of the flange of the first end and the rounded edge of the flange of the second end to form a tucked seam at the connection interface. 2. The method of claim 1, wherein the first end and the second end each further comprise a notch disposed between the flange and the upper edge portion, the flange further comprising an upper tapered edge adjacent to the upper edge portion, the upper edge portion of the first end and the upper edge portion of the second end each presenting a straight edge at the connection interface and wherein the method further comprises: joining the straight edge of the upper edge portion of the first end and the straight edge of the upper edge portion of the second end to form a butt seam at the connection interface. 3. The method of claim 1, further comprising securing the flange of the first end and the flange of the second end together by means of one or more fasteners. 4. The method of claim 3, wherein securing the flanges together by means of the one or more fasteners is sufficient to maintain contact between the straight edge of the lower edge portion of the first end and the straight edge of the lower edge portion of the second end at the connection interface. 5. The method of claim 1, further comprising forming the first end of a polymeric panel by bending the flange thereof relative to the lower edge portion thereof, the notch enabling the flange to be bent relative to the lower edge portion without substantially bending the lower edge portion. 6. The method of claim 1, wherein the first end comprises a first end of a first polymeric panel and the second end comprises a second end of the first polymeric panel opposite the first end thereof, the first polymeric panel having a configuration that brings the first end into proximity with the second end such that the first end is joinable with the second end. 7. The method of claim 6, further comprising configuring the first polymeric panel such that the first end is proximal to and joinable with the opposing second end. 8. The method of claim 1, wherein the first end comprises a first end of a first polymeric panel and the second end comprises a second end of a second polymeric panel. 9. A low-profile light fixture joint, comprising: a first end of a polymeric panel joined with a second end of a polymeric panel at a connection interface, the first end and the second end each comprising:an upper edge portion;a lower edge portion opposite the upper edge portion;a flange extending inwardly between the upper edge portion and the lower edge portion, wherein each flange comprises a lower tapered edge adjacent to the lower edge portion; anda notch disposed between the lower tapered edge of the flange and the lower edge portion;wherein: the lower edge portion of the first end and the lower edge portion of the second end each present a straight edge at the connection interface;the straight edge of the lower edge portion of the first end and the straight edge of the lower edge portion of the second end forming a butt seam at the connection interface;the flange of the first end and the flange of the second end each presenting a rounded edge at the connection interface; andthe rounded edge of the flange of the first end and the rounded edge of the flange of the second end forming a tucked seam at the connection interface. 10. The light fixture joint of claim 9, wherein each flange further comprises an upper tapered edge adjacent to the upper edge portion and the first end and the second end each further comprise a notch disposed between the upper tapered edge of the flange and the upper edge portion, the upper edge portion of the first end and the upper edge portion of the second end each presenting a straight edge at the connection interface, the straight edge of the upper edge portion of the first end and the straight edge of the upper edge portion of the second end forming a butt seam at the connection interface. 11. The light fixture joint of claim 9, further comprising one or more fasteners securing the flange of the first end and the flange of the second end together at the connection interface so as to maintain contact between the straight edge of the lower edge portion of the first end and the straight edge of the lower edge portion of the second end at the connection interface. 12. The light fixture joint of claim 9, wherein the first end comprises a first end of a first polymeric panel and the second end comprises a second end of the first polymeric panel opposite the first end thereof, the first polymeric panel having a configuration that brings the first end into proximity with the second end such that the first end is joinable with the second end. 13. The light fixture joint of claim 9, wherein the first end comprises a first end of a first polymeric panel and the second end comprises a second end of a second polymeric panel. 14. The light fixture joint of claim 9, wherein the respective notches enable the respective lower edge portions to retain the respective straight edges at the connection interface while the respective flanges present the respective rounded edges at the connection interface. 15. A light fixture, comprising: a drum having an encircling sidewall comprising one or more polymeric panels, a first end of the one or more polymeric panels being joined with a second end of the one or more polymeric panels at a connection interface, the first end and the second end each comprising:an upper edge portion;a lower edge portion opposite the upper edge portion;a flange extending inwardly between the upper edge portion and the lower edge portion, the flange having a lower tapered edge adjacent to the lower edge portion; anda notch disposed between the lower tapered edge of the flange and the lower edge portion;wherein: the lower edge portion of the first end and the lower edge portion of the second end each present a straight edge at the connection interface;the straight edge of the lower edge portion of the first end and the straight edge of the lower edge portion of the second end forming a butt seam at the connection interface;the flange of the first end and the flange of the second end each presenting a rounded edge at the connection interface; andthe rounded edge of the flange of the first end and the rounded edge of the flange of the second end forming a tucked seam at the connection interface. 16. The light fixture of claim 15, wherein each flange further comprises an upper tapered edge adjacent to the upper edge portion and the first end and the second end each further comprise a notch disposed between the upper tapered edge of the flange and the upper edge portion, the upper edge portion of the first end and the upper edge portion of the second end each presenting a straight edge at the connection interface, the straight edge of the upper edge portion of the first end and the straight edge of the upper edge portion of the second end forming a butt seam at the connection interface. 17.
