 Disadvantages of Using Incandescent Lights


Sometimes it is a little bit difficult to stray away from the usual, and this is the case with incandescent light bulbs. They’re familiar and do their job – light up a room, but they definitely have disadvantages that should be considered. Today, we are understandably a lot more aware of our environmental impact, hence we are choosing more eco-friendly products, we’re focusing on saving money and cutting costs that aren’t necessary and we’re looking at more practical options in our home, for this reason, incandescent lights are slowly fading away in the background. Here are a few disadvantages that come with using incandescent bulbs that may just make you reconsider your lighting needs.

Financial costs 

We’d say, with confidence, that one of the main disadvantages of incandescent bulbs is that they cost a lot of money to use and maintain. They are considerably more expensive in terms of maintenance compared to other bulbs in the market, and with no quality, advantages to justify the extra payment. An average home, which usually has around 20 to 30 bulbs, can spend hundreds of dollars annually just to keep the lights on. Making the transition to power friendly bulbs, such as LEDs, a very smart move. Although they might cost more upfront, we can assure you that the return on investment will be worth it. When it comes to your house, certain investments and smart buys are completely logical in the long run.

As these energy-saving bulbs use a fraction of the power incandescent bulbs use, and last much longer, your household could be saving nearly $150 on lighting your house annually. Obviously, actual savings will vary from house to house, but it is definitely worth the change.


As you’ve probably guessed from the previous tip, incandescent light bulbs require more energy to run, which is why they cost you more money than necessary. Energy saving is a mutually beneficial situation for all; the less power you use, the more money you save and the more you help the environment. The majority of electricity in this world is still produced by fossil fuels, which means the more energy you use the more CO2 emissions is released into the world’s atmosphere. Little steps, like changing your light bulbs to energy efficient ones, make a bigger difference than you may realise – what have you got to lose really?

Light quality options 

Incandescent bulbs have much more limited choices when it comes to light colours and quality. Compared to newer bulbs like LED light bulbs, incandescent bulbs are ranked low on the colour temperature scale which is why it has that orange tone to it. Although this is a familiar, and sometimes pleasing, they’re not really the best choice when it comes to task lighting. Sometimes it is nice to specifically choose a colour best for a certain room.

Whilst warm, orange tones are great for homely, relaxing settings, they aren’t ideal for spaces that might need clearer, sharper light. For example, kitchens, office spaces and bathrooms very often work better with white, bright lights, making it easier to see exactly what your cooking, working on or cleaning.

That being said, if you are actually looking for a warm orange light, maybe for a cozy vibe, then LED light bulbs can still be the one for you. As we said, incandescent lights have a limited colour option for you to choose from but LED lights are quite the opposite.


This is for those households with young children, pets or clumsy adults – incandescent light bulbs are, believe it or not, a lot more fragile than LED lights. Although this may not seem like that big of a deal, it does add an extra worry to them. One slight knock or a heavy hand and there could be a bit of a mess.

The reason they are a lot more fragile than LED lights, is simply because the glass used is a lot thinner. Although this does allow the light to shine through, it can be very dangerous. Furthermore, if the lightbulb breaks whilst still in the fixture, it can be extremely difficult and unsafe to remove.

Heating dangers

You may have already noticed – incandescent light bulbs emit an extreme amount of heat. This causes rooms to heat up (very undesirable in warm weather) and makes it more likely that the bulb will burn out. If an incandescent bulb burns out you will need to wait a little while to replace it, as you can actually burn your fingers.

There’s also a possibility that an extreme change in temperature can cause the light bulb to burst – especially when the outside temperature is colder. For obvious reasons, this can be extremely hazardous. As well as obvious fire risks, these properties aren’t desirable in the slightest on a practical sense. Although LED lights may appear a little hot to touch, in comparison to incandescent light bulbs, they are a massive improvement.
