# Is there a difference in energy expenditure?

Does the bulb type in it energy consumption? Logically yes. An LED bulb is not the same as an old incandescent one. Now, is there a difference, within the same type of light bulb, depending on the color? For example, is there a difference in consumption between a white light bulb and a warm light bulb? We are going to talk about it in this article. We are going to explain if there really is a difference and what you should take into account to spend less on your electricity bill.

The light bulbsAlthough they are not devices that have a large consumption compared to other household appliances, they can represent a significant part of the bill. This is so, since you have many lights in your home. As there is a large amount, using them correctly is going to be key to spending more or less.

## White or warm light to save

Maybe you want to save on your electricity bill and pay less each month. You may be wondering if you should change your light bulbs to spend less. If we assume that all the ones you have are LED, for example, you may wonder if a cold or warm white light bulb spends more. The quick answer is that this will not influence.

You should know that the energy consumption by a light bulb will not depend on the color or tonality of the light. It doesn’t matter if it’s cold white, warm, neutral… What will depend is the power it has. That power will be measured in watts. For example, you can find a 9 W bulb, a 15 W bulb, etc.

If, for example, you buy a 15 W white light bulb and another, also 15 W, for warm light, the consumption will really be the same. No matter the color, or the hue. In this case, what you should look at are the watts it has. That is what will determine if they are going to consume more or less when lit.

## Tonality can make the difference

Now, leaving consumption aside, we must say that not all lights are the same, nor should we use them for the same. For example, a cold white light is ideal for an environment in which we must be active, such as working or doing an activity that requires good concentration.

Instead, a warm light We can have it in more relaxed environments, where we are not going to be carrying out a specific activity that requires great concentration. We can use them in places other than the house, since not all rooms in the house will be the same in terms of light.

For example, the cool white light We can use it for the bathroom or kitchen. The warm white light can be placed in the bedroom or in the living room. They are rooms that, as you can see, may require a different type of light. Of course, consumption will depend, as we have mentioned, on the power of each bulb.

In short, even if you see that there are notable differences between a warm white light bulb and a cold one, the consumption will really depend on the power that each one has. There you can find differences and it is convenient to choose the model you need in each case.
