Industrial STL-24-2 Stack Light Signal Tower LED

The Signaworks STL-24-2 LED Stack Light is a two-light LED tower beacon designed for industrial signaling on factory floors. As part of Signaworks’ STL line of standard LED andon tower lights, it provides two color segments for at-a-glance status indication—commonly red and green—in a compact stack. It operates at 24V (DC or AC) and draws about 40 mA per light at that voltage, enabling straightforward integration with standard control circuits. Each light segment houses 24 bright LEDs, contributing to clear visibility in bright or cluttered environments. A durable industrial control box is environmentally sealed to withstand demanding settings. Mounting options include flange-mount bases for poles (for example NT-151) and rotating bases (NT-170), supporting flexible installation in machines and workstations. Widely used for signaling such as material requests, supervisor calls, downtime or maintenance alerts, quality checks, and changeover indicators, the STL-24-2 delivers compact, reliable visual communication. Designed for plug-and-play style installation in ready-to-wire configurations, it helps teams deploy visual status indicators quickly and with minimal setup.
