Electrical questions, answered by experts

Pendant lights are very versatile, and you can almost always find one with your preferred style that accepts your preferred bulb. Today, many fixtures use LED bulbs, though it’s still completely possible to find one that uses halogen, fluorescent, or even old-school incandescent bulbs. The manual that comes with your light should tell what types of bulbs you can use with it.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

Yes, California law requires that electricians be licensed by the state in order to do electrical work. However, there is an exception for small jobs valued at $500 or less. In these cases, an unlicensed handyperson is legally allowed to do the work. Limit hiring unlicensed contractors to minor tasks and fixes around your home.

240V is the standard for more demanding appliances in the United States, whereas 220V is more common elsewhere. The voltage isn’t very different in any practical sense.

Appliances in the United States are often bigger than other parts of the world.
