6 Best Low Watt Christmas Lights To Buy This Year


It’s that time of year again – the festive season!

If you’re in the market for Christmas lights, and you want to brighten up your home, both inside and out, there are a few things you need to consider when choosing.

Firstly, you need to know what types of lights you require, and where they’ll be used, as not all lights are suitable for all use cases.

You should also think about how many lights you’ll need to create the effect you want, and what extension options (if any) are available if you decide you want more.

Finally, and we believe most importantly, you must be mindful of the wattage your Christmas lights will consume, as in most cases they’ll be running constantly for several hours a day. Thus, choosing low watt lights needs to be high on your list of priorities.

Christmas lights wattage: Do Christmas lights use a lot of electricity?

Christmas lights, in general, are low watt and thus don’t use a lot of electricity. This is because the vast majority of them use very small LED bulbs, which are by nature low-powered alternatives to energy-guzzling regular lights.

Of course, some Christmas lights are more energy-efficient than others, whilst still providing good quality lighting.

How much do Christmas lights cost to run?

For a set of lights that use 50W, if you leave them on for 10 hours a day, you’d be paying between $0.10 – $0.15 per day.

Now, assuming you’ll keep them running throughout the festive season – roughly 3 months – that’s 10 hours x 90 days = 900 hours. That will cost you just $9.

Not much, but you could still reduce this number considerably by choosing much lower wattage lights, of which there are a few.

We’ve selected 6 for you to choose from, all of which come in at under 45 watts (and a couple that don’t use regular electricity at all).
