When we think of EMF, most of us think of cell phones and such.

Not light bulbs…

But unfortunately, light bulb EMF exists, and some are worst than others.

In today’s article, I highlight the “best” and “worst” lighting options.

Let’s dig in…

Light Bulbs and EMF Radiation: Why Some Bulbs Are a Problem

You’d never think it, but light bulbs can actually be a source of electromagnetic fields (EMF). 


Get a self-paced, step-by-step path to less EMF in your life—without weighing you down with complicated terminology & information overload.

Some types of light bulbs can emit pretty high levels of EMF radiation (thanks to new “smart” bulbs…more on that in a bit). 

Prolonged exposure to EMF can cause all sorts of issues from headaches and irritability to more serious conditions like infertility and chronic illnesses. 

Not good. 

Light bulbs can produce EMF in 4 ways:

  1. Through the use of WiFi
  2. Through Bluetooth capability
  3. Through dirty electricity
  4. Through generating magnetic fields

I knew evvvverything was going “smart,” but light bulbs? Give me a break!

But alas, it’s happening. You can now get light bulbs that via WiFi and Bluetooth. 

The problem is, Smart bulbs or WiFi-enabled bulbs generate radiofrequency (RF) radiation. 

That same type of radiation (that emits from cell phones, tablets, ect) has been found to alter brain waves.

And THAT ultimately leads to hormonal and cellular changes. Biological effects can also include increased sperm damage and growth of gliomas.

Although, let me just pause here and say I don’t think the amount of EMF in a light bulb is enough to do any of those things.

I’m just stating the fact that the new smart bulbs emit the same radiofrequency waves as other Bluetooth-enabled devices.

But even if they’re not smart, many light bulbs generate dirty electricity. 

Dirty electricity occurs when the normal flow of alternating electrical current is disrupted, causing electrical surges and irregular spikes along the wires. 

When dirty electricity intensifies to higher frequencies, they spread to wider areas, thus posing a greater danger. 

Some data suggests dirty electricity is a potential cause of cancer and childhood leukemia.

Types of Light Bulbs & Their Radiation Output

1. LED Lights

LED (Light-Emitting Diode) lights are bulbs that make use of diodes to create light.

They contain a certain chip, usually made of gallium, aluminum, and arsenic – all of which are semiconducting materials. 

Using this chip, the electrons from the electric current moves from a positive layer to a negative one. In this process, energy is released through photons. 

LED lights are structured in such a way that when photons are directed outward, they can produce a steady light source.

Unfortunately, LED light bulbs and electromagnetic radiation often go hand in hand.

I have seen some with surprisingly low readings, so always, it’s important to measure, measure, measure. This is the meter I use.

On top of that, LED lights expose you to blue light, which lowers melatonin production and can affect your sleep. 

These unhealthy sleeping patterns can eventually cause other illnesses and weaken your overall health.

There are also complaints about LED light noise. 

This is appropriately termed “electromagnetic hum” and is produced by EM interferences or incorrect dimming.

2. CFL Bulbs

CFL or Compact Fluorescent Light bulbs are generally less expensive and use less energy than other bulbs.

This type contains a glass tube coated in phosphorus, which contains mercury vapor and argon glass. 

It is through this tube that electricity passes and interacts with mercury to produce a chemical reaction resulting in ultraviolet (UV) light. 

Now, the UV light is not what we see.

Instead, the phosphorous coating is responsible for absorbing the UV so that the bulb can produce visible light.

CFL bulbs can also be a source of dirty electricity and high magnetic fields due to their electrical components.

3. Fluorescent Lights

Fluorescent lights are the usual option for homes, schools, warehouses, and offices. 

These lights contain mercury-vapor gas which excites the electric current passing through and creates UV lights.

The fluorescent light bulbs have a particular coating that interacts with the UV light. 

Once that interaction happens, the inside of the bulb’s tube glows and produces light that’s visible to us.

Although fluorescent lights use less electrical power than incandescent bulbs, they are more dangerous in terms of the radiation they produce. 

Fluorescent lights operate through faster and shorter frequencies that can penetrate cells.

After long exposure to this, our bodies can experience negative effects and developmental disorders in our system.

The flickering of these bulbs is another huge problem.

Fluorescent lights flicker because the magnetic ballast they use doesn’t produce a steady light. (By the way, that magnetic ballast produces very high magnetic field levels.

I was SHOCKED (no pun intended) when I measured my kitchen lights with my TriField meter!

*runs to the store for new low EMF bulbs*

The concern here is that continuous flickering can cause symptoms in sensitive people like:

  • Headaches
  • Fatigue
  • Sleep disturbances
  • Skin problems
  • Eyestrain
  • Abnormal sleep patterns

And that’s not pseudoscience. Just think about people who are prone to seizures. They’re often brought on by flickering lights…

4. Incandescent Bulbs

Out of all the bulbs, the incandescent bulb is the simplest in design and is considered a standard light source. 

The structure of the bulb is made up of a coil, which heats up when electricity passes through.

The inside of the bulb is filled with gas that prevents oxygen from combining with the metal. 

The only thing wrong with this design is that most of the energy is allocated to creating heat more than producing light; therefore it’s not the most efficient.

The good news is that even though these are old-fashioned types of lights, they are the go-to low EMF option. 

Plus, if you observe, you’ll notice incandescent lights produce a yellow or orange tinge – not blue. 

And I’ve already mentioned the problems with blue light. With incandescent bulbs, that’s not an issue. 

A New Threat: Smart Light Bulbs 

I’ve mentioned these already, but I think they deserve a section of their own in this article. 

They’re called smart, of course, because they can be controlled via WiFi or Bluetooth technology.

Many of them use the internet for customizing and scheduling their “on” and “off” times.

But controlling your lights isn’t all you can do with smart light bulbs. You can also equip them with speakers, cameras, and a presence-sensing ability. 

Cool, right? But here’s the catch…

Despite their convenience, they’re by far the biggest threat to your health out of all other lighting options.

That’s because their “connectivity” feature means they operate via radiofrequency waves. And RF radiation was classified as a Group 2B carcinogen by WHO in 2011…

And because they’re LED-based, they also create dirty electricity. 

Then there’s the remote that controls them. If it doesn’t operate via infrared light, then it too emits EMFs. 

Highest EMF Light Bulbs to Avoid

Based on the comparison provided so far, we can safely assume that LED bulbs, CFL lamps, and fluorescent lights are possible sources of EMF. 

They might be convenient and “eco-friendly” but they’re NOT “human health-friendly.”  

LED bulbs, for example, are efficient in terms of operating in low voltage and using less energy to produce light. 

However, this same light source has a power supply that converts 120 v AC to DC voltage – a process that produces dirty electricity and high levels of electromagnetic fields. 

CFL lamps, which are recyclable, can cause more damage to people’s health and the environment because of their mercury. 

Smart light bulbs should be avoided, too, because, despite their modern touch, they radiate a lot of EMF thanks to its radiofrequencies.

And finally, we have fluorescent lights, which may be less expensive than most bulbs, but are actually a source of UV radiation, high magnetic fields, AND a flicker risk. 

Best Low EMF Light Bulbs: What Lighting is the Healthiest & Safest?  

Out of all the choices of bulbs, the safest and healthiest lighting would be incandescent light bulbs. 

First of all, these bulbs produce little to no dirty electricity because their design matches the wiring of most homes. 

Second, due to their simple setup (aka they’re not “smart”), they don’t create RF radiation. 

More specifically, it’s best to purchase Halogen incandescent bulbs. 

These bulbs work the same way as standard incandescent bulbs, but they’re made from stronger material, thus lasting much longer and producing more light. 

Unlike a typical incandescent bulb, the Halogen bulb produces a deeper orange color and doesn’t need time to warm up. So they’re a little more efficient, too.

The next best option would be LED light bulbs that do not have a transformer. The built-in transformer is the issue regarding dirty electricity.

I have seen some that don’t have the transformer and therefore produce much less dirty electricity. 

Side note → If you want to decrease the dirty electricity in your home, check out my Dirty Electricity Filters Review.

If you’re just completely against using incandescent lights, at least consider the following as you shop for LEDs and other bulbs:

  • Choose CFL bulbs that are double encapsulated to prevent the mercury from leaking out of the bulb if it breaks.
  • Dispose of your CFL bulbs carefully so that the mercury doesn’t spill out. If you’re not sure about disposing of them, consider turning them over to Lowe’s or Home Depot for recycling.
  • Go for LED bulbs that do not have a built-in transformer. This type emits lower EMFs and is generally safer for your health.

Tips for Minimizing Light Bulb Radiation When It’s Beyond Your Control

If you find yourself surrounded by hazardous types of lights, don’t worry! 

You can still manage them so you can minimize your EMF exposure. 

Here are some tips:

  • Make sure your lights are turned off when not in use.
  • If you don’t want them for your overhead lighting, at least keep lamps that use incandescent bulbs and use them in the evenings.
  • Keep CFL, LED, and Fluorescent lights away from beds, chairs, nightstands, and places where people spend a lot of time.
  • If natural light is an option, open your windows and part your shades.
  • Be aware of the EMF levels in your home and office. Try to use an EMF meter to measure the levels of radiation around you. Detection can help you prevent bigger problems in the future.

And when you’re at the grocery store or a friend’s house, and there’s literally nothing you can do, distance is key. 

So choose the seat away from the lamp. That sorta thing…

Final Verdict: Do light bulbs give off radiation?

Yes. Some light bulbs are designed in such a way that their mechanism creates EMF radiation or UV radiation. 

The worst offenders are LED bulbs (with built-in transformers), CFL lights, Fluorescent lamps, and Smart light bulbs. 

The thing is…lights are all around us. Unless you work outside 9 hours a day, you’re most likely in the vicinity of artificial lighting most of the time. 

That means your exposure to the EMF they emit is almost constant. 

Upon long, low-grade exposure to EMF, sensitive people can develop some pretty annoying symptoms. 

Ask me how I know…ugh. 

The good thing we have going for us is that there is some distance between us and them since most lights are located on the ceiling. 

My best advice?

Frequently Asked Questions

What type of light bulb gives off UV rays?

Lights that produce UV rays are CFL light bulbs and Fluorescent lights.

Are LED light bulbs safe?

They’re not going to jump off the ceiling and attack you, but LED bulbs do produce dirty electricity, blue light, and if they’re smart – radiofrequency radiation. 

However, LED lights without the built-in transformer are a better, safer option.

5 thoughts on “Light Bulb Radiation”

  1. I have follow up questions. First of all, I have read the following on, “Basically, the A-style or Edison-style incandescent light bulbs that many of you use in your home or business are no longer manufactured because they do not meet the new efficiency standards.” I don’t quite understand —
    *Are the halogen incandescents you recommend still manufactured?
    *Are all halogen bulbs incandescent?
    *What about krypton bulbs instead halogen? Do they perform as well as halogen in terms of emfs?

  2. Hello Jordan, I enjoyed looking at your website. Have you looked at or tested our LEDs at Satic Shield? I’d be willing to send you one to check out just for fun.

    Keep up the good work. What you’re doing is important, own that friend 🙂


  3. Hello!
    Can you please tell me, which LED light bulbs that are “bulbs that do not have a built-in transformer. ” ??? any brands/types you can recommend. in your research as I can’t seem to find the info. THANK YOU FOR THIS!

    I prefer incandescent but in Canada, they have made them obsolete and to find incandescent eventually in Canada as phased them out started 2014 (im holding on as long as I can though have to prepare eventually wont have them 🙁
