When you are looking to purchase lights for you home, you would need to consider the different types of lighting needs for each of your rooms. At Yeelight, we believe that your home should be customised to fit your preferences. In this guide, I will be bringing you through the basics of what to look our for, and the common terms you may come across when it comes to picking out your lights.

1. Wattage

Wattage is the amount of power needed to generate energy for your lights. Having a higher wattage would mean that your lights will have greater power to generate brighter lights.

Do take note that if you are looking to purchase brighter lights, referring to lumens rather than wattage would be helpful to your search.

2. Lumens

Lumens is a measure for brightness. A higher value of lumens would give rise to brighter lights, while a lower value will result in dimmer lights.

It is good to note that more energy efficient lights can have a lower wattage for the same lumens!

3. Lux Level

You can think of "Lux level" as the amount of light that actually fills up a room. If you would like more illumination in your home, finding lights with a higher lux level would be ideal. To understand this better, a hospital would require lights of higher lux levels compared to your average home.
