Why LEDs are Safer than CFLs (Guest Post)

Traditional lighting solutions have become gradually safer over the years, but there is still a gulf between the levels of sustainable, uncompromised operation they offer and the significantly better performance of LED bulbs.

The CFL market contains most types of bulbs, from filament-based models to the more modern energy-efficient fluorescent examples, which means that everyone will have come into contact with them and will probably have an appreciation of why they might not always offer complete safety.

So what are the issues with CFLs and why should LED lighting be seen as a safer alternative for the modern world?

Illumination Issues

One of the oft-cited issues with CFLs is that it can take time before they reach optimum brightness after they are first switched on. During this warm-up period, they will be dimmer, which can result in accidents, particularly if they are placed in areas that need immediate bright lighting, such as stairs, cellars and other potentially hazardous environments.

LEDs, on the other hand, require no warm-up time to reach their full brightness. As soon as you flip the switch, they will be operating at their maximum capability. The quality of the light they provide is bright and clear as well as being far more focused than CFLs if this is what you require.

With the light being diffused less through a wide arc, LEDs can be very effective in specific situations, both commercially and in homes.

Strobe Effect

Another fundamental flaw of CFLs is that they are constantly and imperceptibly flickering, generally at speeds too high to be perceived by the human eye. But this is not always the case and it is possible for any fluorescent light source to produce strange visual effects, or more dangerously to cause seizures and other health issues in certain people.

This means that CFLs can be much more than just an annoyance   they can be dangerous to some people. LEDs do not suffer from the flickering effect, giving you a constant, unbroken source of illumination which will not aggravate medical conditions in those that suffer from them.

Material Composition

CFLs are made from a lot of different substances, many of which are harmful to humans. These include mercury, which can seriously damage the well-being of humans and animals if they accidentally come into contact with it.

Of course, one of the main elements used in the construction of modern CFLs is glass, which can be very harmful when shattered. This means that damaging a CFL in any way can be a real problem because it requires clean-up and a thorough search of the impacted area for glass shards.

LEDs, on the other hand, are not built using such toxic elements or any fragile materials. This means that they are durable and safe, as well as being compatible with comprehensive recycling techniques that help to enhance their green credentials.

Both home and business users should be able to appreciate the benefits offered by LED lighting when compared with CFLs. So when you next come to upgrade your illumination systems, why not consider this cutting-edge technology?

  1. I didn’t know most of these facts. Thanks for the heads up!

  2. Rebecca R. says:

    Very interesting stuff! I will do my research when I need to get new lightbulbs!

  3. I bought a bunch of CFLs when they first come out. I do want to replace them with LEDs eventually, but they are lasting so long and I hate to waste.

  4. While doing final packing before I moved, I knocked over a lamp and broke a cfl bulb. So frustrating to clean up!

  5. Wow! So much useful information! I LOVE your posts, seriously I learn something new every day. This holiday season I upgraded ALL of my Christmas lights to LEDs, and I couldn’t be happier with that decision! I have spent less time playing with fuses, and all of them have stayed on. I also found an adorable penguin ornament that is LED.

    • Aww! Thanks so much Lisa! I am so happy to know you are enjoying my blog! 🙂 We upgraded our outside lights last year to LED and my husband LOVES them! Well, I do too! 😉 The penguin sounds great too! Thanks so much for stopping by!
