Walking down the lighting aisle at any major home improvement store might feel a tad overwhelming. It seems like there's a bulb in every size, shape, strength, and color temperature.

You might not even realize that the right light can make a huge difference. Taking the time to understand which light bulb works best for each room can not only change the room's overall feel but also help with your sleep schedule and brainpower.

A single light bulb can emit anywhere between 300 to 1,600 lumens. You might need to do a little math to figure out how to reach the ideal lumen number. For instance, if you want 2,000 lumens in your living room and you have five light sources, you'll need about 400 lumens per light.

Once you determine the number of lumens, you need to think about the color temperature of light, which is measured in Kelvin (K). The lower the Kelvin rating, the warmer the light. Warmer light tends to be cozier, while cooler light works best for tasks.

Bathroom: Lumens should be between 5,000 to 8,000 and warmth around 4,100 K.

Bedroom: Lumens should be between 3,000 to 4,000 and warmth around 2,700 K.

Dining Room: Lumens should be between 3,000 to 6,000 and warmth around 2,700 K.

Kitchen: Lumens should be between 6,000 to 10,000 and warmth around 4,100 K.

Living Room: Lumens should be between 2,000 to 4,000 and warmth around 2,700 K.

One other aspect you need to take into consideration is the type of bulb and whether you want LED or incandescent. While incandescent bulbs are typically cheaper, you might want to consider LEDs since they last 25 times longer and use 75% less energy. They're more of an investment upfront, but their overall energy savings are worth it. LEDs also typically have lower wattage, and you don't want to exceed the maximum recommendation for the lighting source.

Take this knowledge with you the next time you head to the home improvement store. You'll know exactly what light bulbs to purchase to illuminate your home.
