Making the change to LED bulbs

 

Since the introduction of the compact fluorescent lightbulb (CFL) 20 years ago, there’s been a lot of scepticism about “new and improved” lighting. Traditional incandescent bulbs are cheap to buy, lighten up quickly and cause no problems throughout their lifespan, unlike CLFs which are slow to brighten, expensive to buy and difficult to dispose of responsibly.

Now LED bulbs are the new kid on the block and while many customers don’t like to change their buying habits, it’s worth noting that a small bit of research can yield a large saving on your energy bill. It’s no secret that LED bulbs are dramatically cheaper to run than incandescent bulbs. Take a look at our table to get a better idea of how much you can be saving by switching to LED.
