Do LED strip lights use a lot of electricity?

So you’ve got some design plans and are considering using LED strip lights to create the effect you are after. But what do these cost to run? And how do they compare to other types of light bulbs?

It’s important to know that the wattage of a bulb is not the same thing as its brightness, though there is often a relationship when you stick with one technology. In other words, a 100W incandescent bulb is generally brighter than a 60W incandescent bulb, all other factors being equal.

But when technology changes, you will sometimes see a bulb being described as “equivalent to” another wattage, which has been very noticeable with LED bulbs, where you might see a bulb listed as 20W being advertised as equivalent to a 100W (incandescent) bulb.

Now, it’s clear that LED bulbs are more energy efficient than the Incandescent, Halogen and CFL bulbs that came before them, but what about LED strips?

Are LED strips energy efficient?

People often wonder, “do LED strip lights use a lot of electricity?” LED strips can carry up to 240 individual LEDs per metre. So, are they energy efficient, or are you burning money when using LED strips for room lighting?

Any light strip you buy will provide information on the wattage per meter, such as this Paulmann Clever Connect Stripe LED, which uses 6.5W in total. If you wanted to run these strips around the edge of a 3m x 3m room on all walls, then you’d multiply:

Perimeter of room = 3m x 4 = 16m

6.5 W x 16m = 78 W (19.5W per wall)

An incandescent bulb emits around 1600 lumens of light. The light strip used in this example provides 550 lumens per meter, so a 3m strip is roughly equivalent to a single 100W incandescent bulb in terms of brightness while only consuming 19.5W. Overall, it’s clear that LED power consumption is very low.

Conclusion

As with all things, the more lighting you add, the more it will cost to run, but LED strips are very energy efficient and provide a large source of light with little added heat.

If you are concerned about electricity bills, then considering LED strips is a great way to create amble light with low running costs. If you’re wondering how much power led lights use, be sure to check the wattage per meter so that you can calculate the cost of running them.

FAQs

Are LED strip lights cheaper to run?

The answer to this will depend on how many meters of LED strip you are comparing and to which bulb technology you are referring. A 3m LED strip is comparable in cost to run to a 20W LED bulb and significantly cheaper when compared to an incandescent or halogen bulb. The length of strip you use will determine whether led lights are cheaper to run.

Can I leave my LED strip lights on all night?

LEDs strips are very efficient and emit very little heat. Although you should never cover a light source, you can leave an LED strip on all night without any safety concerns to avoid heat build-up.

How much power does an LED strip use?

A 1m LED light strip will use around 5- to 6.5W.

Is it cheaper to leave strip lights on?

No. You’ll pay for what you use, and there are no long-term benefits to leaving LED strips running when they are not needed.
