Energy efficient light & health

Havas, M. 2008. Health Concerns associated with Energy Efficient Lighting and their Electromagnetic Emissions. Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) Request for an opinion on “Light Sensitivity”, June 5, 2008. 11 pp.

I write this mini report in response to your request for information about Light Sensitivity as it relates to energy efficient light bulbs. It is based on research we are currently conducting that has not yet been peer-reviewed. For this reason I am able to share only a small portion of our results with you at this time.

Governments around the world are banning energy inefficient light bulbs in an attempt to reduce consumption of fossil fuels and the emission of greenhouse gases. However, the energy efficient light bulbs that are currently available may be harming both the environment (mercury content of bulbs is high) and human health (electromagnetic pollution).

The main function of light bulbs is to generate light, which is part of the electromagnetic spectrum (see Figure 1). The original incandescent light bulbs also generate heat (infrared radiation, also part of the EM2 spectrum), which makes them energy inefficient. The newer compact fluorescent light bulbs generate radio frequency radiation as well as ultraviolet radiation (see Figure 1) and many still generate heat although less of it. These frequencies (RF3 and UV4) have been associated with adverse health in numerous peer-reviewed scientific studies and a growing number of people are complaining that these bulbs make them ill.

Instead of promoting compact fluorescent light bulbs, governments should be insisting that manufacturers produce light bulbs that do not produce radio frequency or UV radiation and that are safe for the environment and for human health. Alternative light bulbs are available that are much more energy efficient than CFL, do not contain mercury, do not produce radio frequencies or UV radiation, and do not make people sick. Unfortunately these bulbs are still too expensive for residential use (CLED lights produced by www.realuvcorp.com).

Five Case Studies: DE and EHS

Posted on October 10, 2009

Havas, M. and D. Stetzer. 2004. Dirty Electricity and Electrical Hypersensitivity: Five Case Studies. World Health Organization Workshop on Electrical Hypersensitivity, Prague, Czech Republic, 25-26 October, 2004, 13 pp.


Deteriorating power quality is becoming increasingly common in developed countries. Poor power quality, also known as dirty electricity, refers to a combination of harmonics and transients generated primarily by electronic devices and by non-linear loads. We have assumed, until recently, that this form of energy is not biologically active. However, when Graham/Stetzer™ filters were installed in homes and schools, symptoms associated with electrical hypersensitivity (such as chronic fatigue, depression, headaches, body aches and pains, ringing in the ears, dizziness, impaired sleep, memory loss, and confusion) were reduced. Five case studies are presented that include one healthy individual; one person with electrical hypersensitivity; another with diabetes; and a person with multiple sclerosis. Results for 18 teachers and their classes at a school in Toronto are also presented. These individuals experienced major to moderate improvements in their health and wellbeing after Graham/Stetzer filters improved power quality in their home or work environment. The results suggest that poor power quality may be contributing to electrical hypersensitivity and that as much as 50% of the population may be hypersensitive; children may be more sensitive than adults and dirty electricity in schools may be interfering with education and possibly contributing to disruptive behavior associated with attention deficit disorder (ADD); dirty electricity may elevate plasma glucose levels among diabetics, and exacerbate symptoms for those with multiple sclerosis and tinnitus. Graham/Stetzer filters and meters enable individuals to monitor and improve power quality in buildings and they provide scientists with a tool for studying the effects of dirty electricity. For the first time we can progress from simply documenting electrical hypersensitivity to alleviating some of the symptoms. These results are dramatic and warrant further investigation. If they are representative of what is happening worldwide, then dirty electricity is adversely affecting the lives of millions of people.

GS Filters improve Power Quality & Health

Havas, M. and D. Stetzer. 2004. Graham/Stetzer Filters Improve Power Quality in Homes and Schools, Reduce Blood Sugar Levels in Diabetics, Multiple Sclerosis Symptoms, and Headaches. International Scientific Conference on Childhood Leukaemia, London, 6th –10th September, 2004


Graham/Stetzer filters significantly reduce radio frequency electrical noise on indoor wiring generated by computers, energy efficient lighting, dimmer switches, and entertainment units within the home or workplace and transported into buildings by power lines from neighbouring property. The resultant improvements in power quality in homes and in schools are associated with fewer and less severe headaches, more energy, lower blood sugar levels for diabetics, and improved balance for those with multiple sclerosis. Results are observed within a matter of hours or days. Cases studies for blood sugar, multiple sclerosis, and general wellbeing are presented.
