There are few things more annoying than a lightbulb flickering out when you switch it on — a lot of people aren’t prepared for it, and they often don’t keep spares But by spotting the signs of a fading light bulb, and being prepared with spares, you never need to be without light again.
When to change a light bulb
If the light appears dimmer, then it is sure sign that it will need changing soon. Once the bulb starts to fade, make sure you change it straight away, or ensure that you are stocked up with new ones ready to replace it.
However, look out for bulbs that burn brighter than usual, because this could be a sign of burn out as well.
Flickering or humming noises can also be a sign that a light bulb is about to go, or it could indicate a bigger problem such as a loose wire, so get a professional to check it out if you are not sure.
Another indication a light bulb is about the blow is a reduction in the amount of time the bulb takes to light up.
Different Types of Light Bulbs
Depending on the bulbs you choose, the life span will vary. This section details the most popular options, and outlines how long they’ll last.
Incandescent light bulbs
These light bulbs are getting harder to get hold of today as the move towards greener forms of energy continues, but people are still using them as they are usually cheaper to buy. They have a relatively short life span, and the Consumer Energy Center says you can expect them to last 750 – 1000 hours, but the New York Times says they’ll last for up to 2000 hours.
LED light Bulbs
Although more expensive, LED light bulbs will last much longer and save more money in the long term. Most manufacturers promise that a LED light bulb will last anything from 25,000 – 50,000 hours, thus reducing the need to change them so often; these bulbs can last up to four years.
Low Energy Light Bulbs
Depending on the brand you buy, and the wattage, low energy light bulbs can last for up to ten years, and for many people they are the preferred choice as they are kinder to the environment.
