We put a twist of lime in the luminaire and mixed it all up. ETC's x7 Color System™ combines a balanced recipe of up to seven colors to create evocative color mixes. The Source Four LED Series 2 Lustr array takes the idea even further, with the addition of a lime-green LED emitter. Lime green increases the luminaire's lumen output in open white and lighter tints to make them brighter and livelier, better matching the color of a conventional Source Four fixture. The lime also enriches color-rendering by better marrying the red and blue ends of the color spectrum, for truer-to-life light that fills in the gaps that ordinary LEDs leave behind. Source Four LED Series 2 Lustr We also added more red to the x7 Color System in the Source Four LED Series 2 Lustr array. Working in unison with the lime-green emitter, the extra red means the luminaire can produce ambers, straws and pinks up to three hundred percent as bright as those from the original Source Four LED™. The deeper, richer color from the Source Four LED Series 2 Lustr array will evoke the strongest audience reaction to your sunset, moonlight and dramatic scenes.
