1. A method of making a light fixture, the method comprising:

  • forming a plurality of cavities in a glass substrate, the cavities each being tapered along a depth thereof so that each cavity increases in diameter or distance from a first end thereof to a second end thereof;

    disposing a reflective element on a surface of each of the cavities;

    disposing a lens entirely within each of the cavities; and

    locating a light emitting diode (LED) at or proximate to the first end of each said cavity, so that a plurality of LEDs are provided in a plurality of respective cavities in the glass substrate, so as to enable the associated reflective element to reflect at least some light emitted from the respective LED in a given cavity, substantially conserving &

    endue of the light from the respective LED, and wherein light from the LED in a given cavity passes through the lens before being output from the light fixture, whereinsaid lens comprises, when viewed in cross section, a main body portion and flare portions extending away from the main body portion and away from the LED in the cavity in which the lens is provided, the main body portion having a curved upper surface, each of the flares including a first profile, a second profile and a third profile, the first profile being parabolic in shape and curving away from the main body portion, the second profile extending upwardly and inwardly from an uppermost part of the first profile, and the third profile extending between an uppermost part of the second profile and an end of the curved upper surface of the main body portion.
