Some designers love those sleek lines of recessed light, and some think they're too bright and already passé. But recessed linear luminaires are everywhere: running up and down walls, skimming architectural transitions, marching or swirling along ceilings, and punctuating spaces in pixelated patterns. Slots can provide strong design character to a space, or they can provide subtle, general illumination where troffers take up too much real estate and downlights are too little. There's also a sweet spot where slot lighting - done right - follows the lines of the architecture while providing good illumination with balanced brightnesses.
