The PATLITE LR4 Series 40mm LED Signal Towers feature ultra-bright LEDs, a modular design, and a wide selection of options to take on the most challenging applications.
Features re-designed lens and improved module construction, delivering bright, even light for visibility from further distances (2000mcd output). The re-engineered, completely enclosed sound module maintains substantial water and dust protection while producing loud, omni-directional sound (LR4: 85dB at 1m).
Its sleek, smooth form and rugged body construction are ideal for performance in harsh environments, carrying an IP65 protection rating.
A modular “Twist and Lock” design allows for easy customization and configuration of LED units and sound modules.
Available in 2, 3, or 4-tier models, with 3 mounting options: direct, pole with L-bracket, or pole with circular bracket. Only available in DC24V.
4-tier models include Red, Yellow, Green, and Blue (RYGB) LEDs, 3-tier models include Red, Yellow, and Green (RYG) LEDs, and 2-tier models include Red and Green (RG) LEDs. Each model is 40mm in diameter.
All models include LED modules, flashing/buzzing modules, and a cable.
