EMF and Light Bulbs… Which Light Bulbs are the Best?


What are the typical types of light bulbs? Most are familiar with:

  • incandescent
  • compact florescent (CFL) and
  • light emitting diode (LED) light bulbs.

If you were like me, you have made the switch to those CFLs, aka, compact florescent lights. They were said to be more energy efficient. Sounds good. So, I swapped out my incandescent lights about 3 years ago. I also liked the color of the daylight bulbs, so got those. Honestly, at the time, I didn’t look into the research. I heard they were “better” and went with it…

Well, turns out, those are NOT the best choice.

Wait, what? Why?

Actually, now that I think about it, who ever thought those horrid florescent lights in stores or office buildings were appealing? But yet, millions of consumers have brought them into our homes. And continue to do so, unaware of the potential health hazards.

Here is an excellent post by on the dangers of CFLs. Please take a look, as I could not say it better and there is a nice graphic that depicts dirty electricity levels.

CFL light bulbs represent a triple threat to your health rather than the loveable energy friendly devices that industry and govenrment would have you believe.

Ugh. I had no idea. I have been exposing my family to this, all in the name of “energy efficiency”.

Alright, so now what? LED? They have come down in price, and they are more energy efficient than CFLs, BUT…

The Douglass Report says, LED light is far too heavy on the blue and violet end of the spectrum — and new research out of Spain confirms that too much blue and violet from LED lights can do serious damage to the retina.

More specifically, research by Dr. Celia Sànchez-Ramos of Madrid’s Complutense University shows that LED lights can damage pigment epithelial cells.

That’s the type of damage that doesn’t just lead to vision loss — it can also result in macular degeneration.

According to Harvard Health, “blue light has a dark side”.

While light of any kind can suppress the secretion of melatonin, blue light does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours).

If blue light does have adverse health effects, then environmental concerns, and the quest for energy-efficient lighting, could be at odds with personal health. Those curlicue compact fluorescent lightbulbs and LED lights are much more energy-efficient than the old-fashioned incandescent lightbulbs we grew up with. But they also tend to produce more blue light.


Alright, so our options are:

  1. less efficient incandescent lights, but safer, no known harm to human health
  2. energy efficient, but “triple threat” CFLs, that have shown to cause harm to humans
  3. more energy efficient LEDs but may cause serious adverse eye damage, including the potential to increase risk of macular degeneration

Oh, also, many countries are now BANNING incandescent lights. Some claim that the ban on incandescent lights in the US were overblown, but I found this article from on policy to be very interesting.

Amy Ridenour reports,

When General Electric blamed “a variety of energy regulations that establish lighting efficiency standards” for the closing of incandescent light bulb factories in Virginia, Ohio and Kentucky, its PR team left out a critical detail: General Electric and fellow light bulb manufacturers Phillips and Osram Sylvania had lobbied for those regulations.

Ignore claims that the incandescent light bulb ban was imposed to fight global warming. The motive behind the bulb ban is money: Incandescents have a low profit margin.

She goes on to shatter the other myths surrounding light bulbs, check it out, great content.


Have you installed light DIMMERS? Thought you were been more efficient? Well, you may want to reconsider them.

Dimmer switches put out a wide range of radio frequency and creates dirty electricity.

If you really like dimmers and prefer to keep them, the ones that you tap- high, medium, low emit the least amount of EMF, whereas the sliding dimmers are the worse offenders.

Here is a great video, that visually shows, with a meter, the different levels of EMF coming from different types of light bulbs.


What options are we left with?


A good lesson learned: when it comes to picking the safest products, we cannot just listen to the hype, “the buzz”. We have to do some research… luckily, that is why I write this, to offer you some resources and links to learn more. And there are many others who have some great content.

I heard a recent podcast with Sam Milham, MD, MPH and he is an authority on dirty electricity. Here is a video where he measures and discusses how to mitigate dirty electricity.

He also mentioned that “there is a dark side to green”.

I found this article to be of interest, which discusses the irony of going green

Also worth checking out: this article is an in-dept look at light and eye health, from Neurosurgeon, Dr. Jack Kruse. Interesting info and sheds some light for those who suffer from myopia (can’t see far away) or have had cataract surgery or spend a lot of time under fluorescent lights.

Update: I found these low blue light LED bulbs.
