{"product_id":"blackjack-quadra-linear-pendant","title":"Quadra Linear Pendant | Blackjack Lighting","description":"\u003cp\u003eQuadra is a linear pendant built from squares. A long, flat frame of Polished Chrome, 47.1 inches by 6 inches, is divided into a row of square cells, some filled with luminous LED panels and some left open, so the fixture alternates between light and air along its length. It hangs from four almost invisible cables and is so thin in profile that from the side it nearly disappears.\u003c\/p\u003e\n\u003cp\u003eThat airiness is what makes Quadra feel lighter than its size. Over a long dining table or kitchen island it reads as a floating graphic pattern, a strip of bright and empty squares rather than a solid bar, and the polished chrome frame picks up reflections from the room. Choose the downlight version for light on the table, or the up and down version, which also washes the ceiling and makes the whole fixture appear to hover in its own glow.\u003c\/p\u003e\n\u003ch3\u003eDesign notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight in a pattern:\u003c\/strong\u003e LED panels alternate with open squares, so light and transparency share the same frame.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThin, long proportion:\u003c\/strong\u003e 47.1 in (119.5 cm) by 6 in (15.3 cm), almost a plane when seen from below.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolished Chrome:\u003c\/strong\u003e a reflective frame that catches the room and the glow of the panels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo light directions:\u003c\/strong\u003e downlight only, or up and down for a ceiling wash as well.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFloating suspension:\u003c\/strong\u003e four fine cables, field adjustable from 4 in to 97 in overall.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"width:36%;min-width:170px;text-align:left;vertical-align:top;padding:6px 12px 6px 0;\"\u003eManufacturer\u003c\/th\u003e\n\u003ctd style=\"vertical-align:top;padding:6px 0;\"\u003eBlackjack Lighting, Buffalo Grove, Illinois\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"width:36%;min-width:170px;text-align:left;vertical-align:top;padding:6px 12px 6px 0;\"\u003eModel\u003c\/th\u003e\n\u003ctd style=\"vertical-align:top;padding:6px 0;\"\u003eQuadra Linear Pendant (Down Light;

Trained in industrial design at Syracuse University, Blackman began his lighting career in 1984 at Sonneman Design Group, then founded Blackman Design Associates in 1988, designing decorative and architectural lighting for manufacturers including Kichler. He launched Blackjack in 2013 in suburban Chicago, now based in Buffalo Grove, Illinois, to build fixtures conceived for LED from the first sketch.\u003c\/p\u003e\n\u003cp\u003eHis argument is that the LED should change the shape of a light, not just its efficiency. Rather than hiding a new source inside old bulb-and-shade forms, Blackjack designs around the small, flat, cool-running LED: thin discs, slim rods, glowing rings and lenses that let the light itself become the object. In his own words, \"Decorative lighting by its nature is not primarily about optimizing lamp efficiency, it is primarily about decoration!\" Quadra makes the flat LED panel itself the ornament, setting glowing squares and open ones side by side in a frame of chrome.\u003c\/p\u003e\n\u003ch3\u003eQuestions\u003c\/h3\u003e\n\u003ch4\u003eWhat is the design idea behind Quadra?\u003c\/h4\u003e\u003cp\u003eTo make a linear pendant that feels weightless.
