LEDs vs. incandescent light bulbs

LEDs vs incandescent (Bulb vs Bulb showdown!)

So, which bulb should you have in your home? In this article, it’s LEDs vs incandescent – we compare both bulbs to help make the decision process a little easier.

Incandescent light bulbs have been around for over 150 years. During that time, they’ve been the preferred lighting method of choice, producing their trademark yellow glow for generations.

However, in recent years the sales of incandescent light bulbs have steadily declined, mainly due to the development of a new kid on the block – LEDs.

Initial cost

Incandescent light bulbs are extremely cheap, with some available for as little as 49p! LEDs, on the other hand, can vary in price, but you’d be hard pushed to find a quality bulb for under £4, so it’s hard to compete on the initial cost. However, the long-term savings of LED light bulbs are another matter.

LEDs can last for up to 50,000 hours, depending on the quality of the bulb you buy.  Incandescent bulbs, on the other hand, only have a lifespan of up to 2,000 hours. So, whilst initially being more expensive, the long-term money-saving benefits are clear to see.

Energy usage

A 40w incandescent bulb is comparable to a 5w LED bulb, making LEDs much more energy efficient. In fact, every incandescent bulb you swap for an LED one saves you £7.50 a year on your energy bills. So, replacing ten incandescent bulbs for LED ones could save you a whopping £75.

Green credentials

Many environmental groups have labelled incandescent light bulbs as harmful to the environment. Not only do they waste electricity by producing an excessive amount of heat (90% of an incandescent bulb’s energy is given off as heat), they also emit a substantial amount of carbon dioxide. LEDs, however, produce next to no heat, and emit significantly less CO2.

Instant light

While CFLs were notorious for having a long warm-up period, sometimes taking minutes to reach full brightness, both incandescent and LED bulbs provide instant light from the get-go.

The results speak for themselves

It’s fairly clear to see which bulb is the winner here. Whilst traditional incandescent bulbs may be cheaper to buy from the outset, you can’t beat the long-term energy and money-saving benefits of LEDs!
