No, sconces don’t have to be hardwired, but they can be for a more permanent solution. Sconces come in various styles, sizes, and finishes as well as types of installation. Plug-in wall sconces can be plugged into a nearby outlet, and battery-powered sconces can be mounted to the wall. 

Smart light switches are designed to work with most traditional light fixtures and wiring. However, there are several compatibility factors to consider. Some smart switches require a neutral wire to function, which may not be present in older homes (typically built before 1985). If you plan to use a dimming feature, ensure your LED bulbs are specifically the dimmable type. Additionally, a stable Wi-Fi connection is necessary for remote control, though some models may use other standards like ZigBee, which would require a compatible smart home hub.

Both can and canless lights have distinct advantages, and the better option depends on your specific needs and preferences. Canless lights are often preferred for modern homes due to their slim, low-profile design, energy efficiency, and ability to fit in tight spaces with less ceiling depth required. Can lights, or traditional recessed lights, provide a classic look and may be better for high ceilings or areas that need stronger, more focused light. While they can be durable, they typically require more ceiling space and installation work. Ultimately, you should choose canless lights for a modern look and energy savings, or opt for can lights for a traditional aesthetic and robust lighting in larger spaces.

In the case of electrical overflow, an ungrounded outlet should trip the circuit breaker, staving off dangerous scenarios. However, this is not always the case, especially if the wires and circuit breaker are worn down or damaged in some way. Ungrounded wires melt over time as they are introduced to more and more electricity. In other words, a circuit breaker offers protection in most instances but not always, and that’s where the danger lies with ungrounded outlets.
