16. The lighting module of claim 12 , wherein the window includes a seat extending along a perimeter of the window such that the sea is engaged with a mating portion of the frame and the gasket is positioned between the seat and the mating portion.

17. A method of replacing a window frame on a lighting module, comprising:

manufacturing a housing defining at least one opening;

positioning an array of light-emitting elements within the housing;

assembling a window frame that includes:

a frame selectively removable from the opening of the housing; and

a window that is operably secured to the frame with one or more retaining elements removable from the frame; and

one or more tabs integrally formed with the frame that extend away from the frame to define a space into which the edge of the removable window is positioned, the removable window filling only a portion of the space when secured to the frame leaving an open space adjacent to the window, and wherein the tabs are positioned apart from the retaining elements and help prevent the window from separating from the frame; and

operably securing the window frame within the opening of the housing with the one or more tabs and retaining elements.

18. The method of claim 17 , further comprising removing the window frame from the opening of the housing and replacing the window frame with a replacement window frame that includes:

a replacement frame removable from the opening of the housing; and

a removable replacement window that is secured to the replacement frame.

19. The method of claim 17 , wherein the window frame further includes a die-cut expanded PTFE gasket that is positioned between the frame and a portion of the window that is secured to the frame.
