Technically speaking, smart bulbs do use a small amount of electricity even when the power is off, but it isn’t anything you’ll notice on your electric bill. In most cases, it would amount to a penny or two per month per smart light bulb.

Do smart bulbs use electricity when not on?

There is one main reason your smart bulb will use power when off and it falls under the term vampire power, or as it’s more traditionally called, standby power. So the light itself won’t draw power, not that it does much when on either, being LED.

How much energy does a smart light bulb use?

Research from various brands and types of smart bulbs indicates that most draw between 0.2 and 0.5 watts while in standby. This equates to 0.0002 and 0.0005 kWh (kilowatt-hours). To put this into context, a standard AA battery could power 0.2 watts for approximately 15 hours. So it’s a minuscule amount of power.

Does turning LED lights on and off use more electricity?





Despite myths you may have heard, turning your lights on and off doesn’t use more electricity than leaving your lights on. Turning off the lights when you aren’t in a room is one of the easiest ways to save energy.
