  1. Thanks for the clear explanation about both led and incandescent. In conclusion i agree with you… switch to LED lights and start saving on your power bills.

    There was no comparison in EMFs emitted between the three types of light bulbs.

      Not true as I clearly stated: “From an EMF standpoint, the lower current draw of an LED is attractive as that also lowers the magnetic field intensity.” Therefore, LED lighting generally has a lower magnetic field than that of other associated lighting in case you didn’t make the connection in my statement.

      Please be a bit more thorough in your analysis of my commentary – thank you!

    Hello, this article is great. I have a question: which of the 3 light bulbs is least susceptible to dirty power? Asking from a 3rd world country where virtually every appliance I have needs a regulator cuz the grid is just so… dirty. From experience all 3 seems to fail randomly – incandescents wink out, CFLs get black spots, and LEDs flicker. With your expertise, which one should theoretically last longer?

      Good Question,

      >which of the 3 light bulbs is least susceptible to dirty power? (regarding the 3 main types of electrical lighting bulbs)

      This isn’t something that I have had to contend with and you are a bit vague about the symptoms of “winking out” and getting “black spots”. Are you describing momentary flickering or are the lights actually going bad permanently? Offhand, incandescent bulbs are typically the most rugged with regard to dirty power and you might want to look into Industrial Grade bulbs. Otherwise you might try LEDs on a UPS supply or at least a surge protector power strip / multi-outlet device.

      A portable cordless LED lamp with a built in battery is another thought. That and there are always candles and alcohol lamps / Coleman lanterns, but with the greatly increased risk of fire. If you use a combustible fuel source, never leave it unattended or too close to something flammable.

      Good Luck!
