{"product_id":"etc-s4wrdt120","title":"ETC S4WRDT120 Source 4WRD II LED Retrofit Upgrade | No Connector","description":"\u003cp\u003eThe ETC Source 4WRD II LED retrofit is engineered for lighting professionals who need to modernize existing Source Four inventory without replacing entire fixtures. The nondestructive installation takes under a minute and, in most cases, can be completed without disturbing the fixture's focus — a critical advantage for theatres, houses of worship, and hospitality venues operating on tight changeover windows.\u003c\/p\u003e\u003cp\u003eFor integrators and production electricians, the S4WRD II addresses the full range of installed lighting scenarios: DMX control over RDM-capable networks via RJ45, line dimming compatibility, and a traditional LED dimming curve that behaves predictably on conventional dimming infrastructure. With selectable color temperatures spanning 3200K and 5900K across 80 and 90+ CRI options, it suits everything from theatrical stages to retail environments demanding accurate color rendering.\u003c\/p\u003e\u003cp\u003eOperating at 150W typical on 120V versus a standard HPL lamp, the retrofit delivers meaningful energy savings across large fixture counts — up to 14 units per 20A switched circuit. The die-cast aluminum construction and active thermal management keep fixtures running cool without lamp replacements, reducing ongoing maintenance overhead for universities, exhibition centers, and permanent installations where access is limited.\u003c\/p\u003e\n","brand":"Electronic Theatre Controls, Inc.","offers":[{"title":"Default Title","offer_id":52446375477432,"sku":"54311","price":865.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/141259_ETCS4WRDCII_ALT1.jpg?v=1783698112","url":"https:\/\/soundpro.com\/products\/etc-s4wrdt120","provider":"SoundPro","version":"1.0","type":"link"}
