The Pretty Good House Blog: Low Voltage Lighting

Low-voltage lighting is starting to show up as a whole-home option, running fixtures on stepped-down DC power instead of standard household wiring. The idea: one centralized power system feeds recessed lights, pendants, sconces, and even backlit mirrors throughout a house, using smaller wires and fewer of the bulky drivers (the devices that convert household voltage down to what a fixture needs) that older low-voltage setups required. The comparison being drawn is to LED bulbs, which went from an $18 novelty to a near-total replacement for old bulbs in about 15 years, cutting energy use and cost along the way. The suggestion is that low-voltage systems could follow a similar path, becoming a normal choice for lighting a home rather than a specialty product.

This is early-stage industry news, not a finished product ready for typical homeowners to shop for. It comes from a builder describing preparation for his firm's first installation of this kind of system, in partnership with a passive-house builder, using equipment from a manufacturer called Cleanlife. There's no pricing, availability timeline, or rebate information here, and it's not yet something you'd bring up with an electrician for a standard remodel.

If you're weighing lighting upgrades now, this doesn't change what's available to you today. It's worth knowing the concept exists, since whole-home low-voltage systems may become more common in new construction and major renovations in the coming years, similar to how LED bulbs eventually became the default.
