Description
Principal Sloan Spectrum Gen 2 RGBW LED Modules - 24V
The Principal Sloan Spectrum Gen 2 LED Module is a 24V RGBW lighting solution designed for illuminated channel letters and commercial signage. Featuring independent red, green, blue, and dedicated white LED channels, these color-changing LED modules provide versatile lighting options when paired with compatible Principal Sloan PWM controllers.
Available in 1-diode and 3-diode configurations, Spectrum Gen 2 LED modules offer compact construction, low power consumption, and flexible mounting for new channel letter installations and compatible retrofit applications. The dedicated 6500K white channel provides white illumination without relying solely on RGB color mixing.
Designed for channel depths of 4 to 8 inches, these IP65-rated LED modules feature peel-and-stick or mechanical mounting options, reliable operation in temperatures from -40°C to +60°C, and a 10-year product warranty with a 5-year limited labor warranty.
