The 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.
For 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.
Operating 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.
