Most people want to know between lamps and lights which one is cheaper to use.

Light consumption cost can actually be managed by every individual to pay less cost while still enjoying the quality light at home. Knowing how to choose the lighting system that has the lowest cost with highest power supply will help you save some money.

The cost of power consumption is measured by the unit of watts you consume. Whether lamps or light, the cost is measured based on the watts of the globe.

For lamps and lights with 60-watt globe, the cost will be the same. A 20-watt light, for example, is cheaper to use than a 40-watt lamp. This calculation is based on power consumption in the United States. Therefore, home owners should use lower watts if they want to save money.

Invariably, you have nothing to worry about because you can control the cost of power you consume daily, weekly and monthly.

In this article, you’ll discover how to reduce the cost of power consumption, while still enjoying the same quality of light.

Watts Make The Difference In Cost

The difference in the cost of power usage isn’t because you use lamps or ceiling lights. No! What makes the difference in the cost is Watts.

Before we proceed, let’s quickly define watts; 

Watts is the measure of electricity power in units. Based on the International System of Units; watt is the derived unit of 1 joule per second, which quantifies (monetary term) the rate of energy supply. 

The cost of power consumed by lamps and lights is dependent on the amount of unit of watts. Irrespective of the brand of lamps or lights that you have, isn’t what determines how much you’ll pay.

However, the cost of power is based on units of watts you consumed whether you’re using lamps or lights.

Electricity power is calculated based on the units of watts they supply to your home or office. So, to reduce the cost of power, you have to reduce the units of wattages you consume.

Most people think the high cost of power bills they pay is as a result of the ceiling light or wall light. 

No! What determines how much you pay for a power bill is a function of the amount of watts you consume.

So, if a unit of watts is the determinant factor for power billing, then, “how do I calculate the amount watts use either lamps or lights?”

To know the cheapest power consumption between lamps and light, then you have to know the watts of globes each uses.

Both lamps and lights (Ceiling and wall lights) globes have a number of watts they can hold or use. 

The units of watts are usually written on the globe. Mainly, the unit of watts is usually written close to the screw or pin cap. 

You can also look at the globe pack to know where the watts is written. The unit of watts each globes have is what determines the amount you’ll be charged per usage.

How to Calculate The Of Unit Of Watts  

You can easily calculate the unit of watts when you know the globes watts. Each globe has their units.

The wattage of bulbs is what determines the brightness. Higher globes wattage the brighter the globes. Likewise the lower the unit of watts the lower the brightness.

The lamps and lights (Ceiling or wall lights) globes watts ranges from 20 watts to 600 watts. 

To know the cost of lamps or lights based on watts, you need to have the ideal of what a unit of watt will cost. 

The table below shows the cost of watts by different globes.

Globe TypePowerCost /dayCost /YearSaving
Energy Saving8W0.67p2.4480.0%
Energy Saving11W0.92p3.3581.7%
Energy Saving15W1.25p4.5780.0%
Energy Saving18W1.50p5.4882.0%

Generally, most of the house lamp watts range from 40-watt to 60-watt, while the lights range from 60-watts to 75-watts. 

For example, if the lamp globes in your house have 20-watt and the light globes have 20-watt. It simply means that the cost will be the same.

In this scenario, the cost of both lamps and lights are the same. 

But if the wattage of a lamp’s globe in your house is 30-watt and the light globe is 40-watt, then the lamp will be cheaper compared to light.

The cost of what you’ll pay as a power bill is the unit of watt you consume. Likewise, the higher the wattage, the higher the brightness.

Assuming, you have a lamp that’s using an Energy bulb/globe of 11-watts, the cost per day in point will be 0.92p, while the light/ceiling uses an Energy bulb/globe of 15-watt, the cost per day in point will be 1.25p.

From the illustration above, it means light will be more expensive compared to lamps. The only factor that shows you which is cheaper or costlier is watt.

How to Minimize The Cost Of Power Usage

Apart from the watts, there are other ways you can minimise the cost power usage.

Switching off your lights from the source in your house after usage, will reduce the cost. Now the question is between lamps and light which can you easily put off after using.

Since, you’re charged based on the unit of watts, then you can control the amount of power bill you pay. 

Most people are in control of the cost of power they consume daily. You can do the same thing.

The easiest way to control the cost of power is to learn how to often put off your light after usaged.

Next, between lamp and light in your room or office which one can you easily switch off. Check the one that is within your reach, which you can easily turn-off and start using it.

The total cost of a power bill in a month is always lower when you always turned-off the power after use.

You will pay less when you have globes with lower units of watts and always turn-off the power after usage.

If you really want to reduce the cost of power bill, then you have to learn how you can easily turn off your light after use.

Is an LED Lamp Cheaper Than An Incandescent Lamp?

The LED lamps are cheaper to use than the incandescent lamps. The difference in the cost is in the watt they consume.

The LED lamp consumes less power compared to incandescent light. The incandescent consume high power.

Higher power means higher cost, when it comes to cost. To reduce the cost of money you spend, then reduce the unit power power.

The LED lamps produce higher brightness with lower power consumption. This is why most people switch to buying LED lamps.

The lamp with LED light with smaller watts produces brighter light with lower cost of power.

Does Plugging Lamps Into Receptacles Reduce The Cost?

Many people think receptacles help to reduce the cost of power. The function  of the receptacle is to supply power from the house source to the lamp.

Receptacles don’t reduce the unit of watts neither does it increase the cost. What reduces the cost of power is watts.

If the unit of watts you consume is lower than the amount you will pay will always be lower. 

What determines the cost of power is not receptacle but the number of units you consume.

Another way to reduce the cost of power is alway turn it off when you’re not using it — thereby reducing watts usage.

So, in order to reduce the cost of power usage, always turn off your lamp and go for a globe that has lower watts with better lumen.

Frequently Ask Questions

What do the star ratings on lights mean?

Simply put, starting rating denotes how energy efficient a certain appliance is. The higher the star rating is, the more efficient is the appliance which in turn leads to cheap energy bills. It’s also one of the first things you should check when buying lights or any other electricity-powered appliance.

How to save on energy bills even with high-power lights?

You can choose a dimmer set of lights for the patio, balcony, or even your bathroom to save on energy bills. Sure, you don’t appreciate dark corners in your home but that doesn’t mean that every part of your house requires the same lighting. For instance, active parts of your home like the study, living room, or kitchen should get bright lights. Any place that doesn’t require you to do an activity that requires clear vision should do okay with dimmer lights. This way, you not only save on your energy bills but also add an aesthetic feel to those areas.

What are some affordable alternatives to LED lights?

If you cannot go for LEDs at the moment, CFL lighting is the next best option for you. No doubt, they are quite expensive upfront but last much longer than incandescent bulbs. Also, they are known to use at least 80% less energy compared to regular lights. If you are ready to invest a little more, you can also go for fluorescent tubes that last twice as much longer and consume way fewer energy units.

Why do you need to clean your light fixtures periodically?

Dust-laden lights and bulbs often reduce the brightness of the light, making you feel like it’s time for a new, high-watt bulb. Cleaning these fixtures periodically will keep your room brightly lit even without increasing the power of the bulbs.

Should you use one high-watt light or multiple low-watt lights for energy savings?

It might come as a surprise but a single, high-watt light will cost you much less on energy bills compared to multiple low-watt lights. If you want to light up every single corner of your home, installing multiple lighting fixtures is pretty much the only effective way. For example, the energy used by one 100-watt bulb will be significantly lesser than the energy used by two 50-watt bulbs.

What color lamp liners are best for energy savings?

When buying a lamp liner, always go for whites, beige or similar light hues. The white shade will reflect the light better, making your room seem brighter even if you are using a low-watt bulb. After all, the brightness of your home isn’t just dependent on the light source alone but also the color and placement of other fixtures and appliances in your home. Similarly, you can use pastel paints for the wall and curtains and go for neutral colors for the furniture. The relationship of colors with respect to light is simple — dark colors absorb light making the room look dimmer whereas light colors reflect light, making the room look brighter.


Most importantly, the amount of lamps or lights you consume in your house or office is what determines the cost.

The cost of power isn’t controlled by either lamps or lights. Because they’re just channels through which the voltage passes to light up the globes.

When you want cheaper lighting-up your house or office, go for smaller watts that still produce the quality of light you need.
