The Laserworld EL-400RGB S is a compact yet dynamic 400 mW RGB laser projector designed for DJs, bars, and small events. Combining 650 nm red, 532 nm green, and 445 nm blue diodes, it produces seven brilliant colours, including a crisp bright white. With a beam diameter of approximately 3 mm and a low 2 mrad divergence, the unit projects sharp aerial effects such as tunnels, waves, and sheets that remain visible across busy dance floors. Control flexibility makes it suitable for both beginners and professionals. Users can choose from automatic plug-and-play operation, beat-sensitive sound-to-light mode with an adjustable microphone, or integrate it into larger lighting systems via 9-channel DMX. The 15 kpps scanners ensure fluid graphics and patterns without flicker. Weighing only 3 kg and housed in a rugged metal chassis, the EL-400RGB S is portable, durable, and compliant with Class 3B safety standards, featuring a keyed switch and interlock.
