Why DC Lighting?

In this new era of DC renewable power and AC/DC hybrid building nanogrids, Marshall DC lighting adds sustainable value to building power infrastructures, empowering grid resiliency & optimizing the value of renewables… DC lighting “Direct-Connects” (DC-to-DC) with renewables (solar/battery storage), unlocking optimized grid resilient strategies for lighting security, cost control, carbon reduction, and load sharing possibilities.

Three (3)“Whys” of DC Lighting

  1. Why DC over AC? DC-to-DC "Direct-Connect” to renewables catalyzes grid resiliency…
  • Enables optimized load management solutions with solar &/or battery storage
  • Low voltage Class 2 wiring applications (24DC to 60DC)
  • Greater efficiencies upward of 15% (no AC-to-DC conversions)
  • Decrease carbon footprint
  1. Why DC Lighting & Renewables? DC Lighting + Renewables = Optimized Load Sharing Solutions…
  • Optimize load sharing among power sources & electric cost control
  • Mitigate risk of lighting downtime with greater lighting security
  • Reduce installation & material costs
  • Easily quantify measurable electric cost savings via renewables off-set
  1. Why Pont of Ethernet (PoE) for DC Lighting?  The 4 “C”s of PoE…
  • Copper; 60% less copper (lower AWG wire)
  • Conduit; 100% less steel (no conduit)
  • Change Orders; 100% flexibility (software change orders, open standards)
  • Conversion Costs; 30% lower operating cost (no AC-to-DC conversion in every fixture)
