What to consider before buying a smart light bulb

Bulb vs switch

Smart light bulbs are the best option to go with if you want to control your bulbs individually.

Bulbs are easier to install but you might need an electrician to do an overhaul and install the smart switches.

White vs Color

Smart light bulbs come in two colors: white and color bulbs. With white bulbs, you can turn them on and off as you would with the standard bulbs, and are cheaper due to their simplicity.

Luminance refers to the amount of light produced while watts is the amount of energy required by a bulb. This directly affects the brightness of your smart light bulb.

Lights with a lower lumen (25, 000K – 2, 700K) are softer than lights with a high lumen (6,500K – 8, 500K) and have a lower temperature. You want to avoid huge electricity bills at the end of the month. It’s recommended to find a smart light bulb with a lower watt consumption and a wide array of lumens.

Voice Assistant
