1.
light, lamplight, glow
A gentle light from a lamp, candle, or similar source. Implies a warm, soft quality of illumination rather than bright or harsh light.
Usage
Written as 灯り (with the kanji 灯) to emphasize the sense of lamplight or flame-based illumination. The homophone 明かり uses a different kanji and emphasizes brightness in general. Both readings overlap considerably in practice, but 灯り tends toward warm, ambient light.
