The Biden Administration banned the sale of incandescent light bulbs for general service lamps in 2023. All household light bulbs must meet a minimum efficiency of 45 lumens per watt, three times that of a standard incandescent light bulb. 

The main motivation was to improve energy efficiency and reduce carbon emissions. It is expected that banning incandescent light bulbs will cut over 200 million metric tons of carbon emissions over the next 30 years. Some bulbs are exempt, like chandelier lights and Christmas lights.

Ultimately, the best device depends on what you’re measuring. A voltmeter only measures volts, while a multimeter measures volts, current, resistance, humidity, and possibly much more, depending on the model. If you think you’ll need to measure more than volts, consider investing in a multimeter so you have a tool that can help you with various household projects.

Motion sensors are actually an eco-friendly option and don’t use as much electricity compared to other lighting sources. Motion sensor lights are always on “standby,” which requires a phantom source of power at all times, but for most sensor light models, this is only a small amount of electricity—typically around one watt of power.

Yes, electricians must be licensed, certified, and in most cases, insured. Licensing requirements vary by state and local municipality, but most U.S. municipalities require electricians to hold an electrical contractor’s license. It's always a good practice to confirm requirements with your local municipality. Even if licensing is not required in your area, hiring a licensed and experienced electrician often leads to a better end result.

A license is a legal requirement to operate a business and is necessary for pulling project permits. Certifications, on the other hand, are typically voluntary and demonstrate a certain level of expertise. In some cases, a certified electrician may send an apprentice or journeyman to perform the work, but they must operate under a primary electrician who holds the proper license.

Before hiring, you should verify the electrician's license, insurance coverage, and any third-party certifications. You can use Angi’s contractor licensing search to confirm a pro's license status. Additionally, businesses with the “Angi Approved” badge on our platform meet strict criteria, including having the required state and local licenses, passing a background check, and maintaining a high average rating.
