BackLED M Plus HO G1

The IP66-protected and robustly encapsulated modules of BackLED M Plus HO G1 are joined by flexible cables, have a long lifespan and module efficacy of up to 101 lm / W. This makes BackLED M Plus HO G1 ideal for use in signage and illuminated advertising, including outside (if you install it in enclosed light boxes or channel letters). You can also use BackLED M Plus HO G1 for the LED backlighting of small and / or flat channel letters and single or double-sided light boxes. With several options for quick and easy mounting, uniform illumination at high LED pitches (thanks to Square Lens technology) and consistent white light (SDCM < 3) BackLED M Plus HO G1 gives you significantly better application efficiency than systems without lenses, is ENEC certified and comes with a 5 year guarantee.
