Q&A Sunday: LED Bulbs vs. Full-Spectrum Bulbs
In terms of BTB feng shui, what is the opinion of LED bulbs? Do they emit EMFs? I thought full-spectrum bulbs were better.
Rita, on How to Buy New Light Bulbs Without Guessing
Hi Rita,
Thanks for your question! Feng shui doesn't really take this sort of detail into consideration, and in my work with BTB feng shui, we haven't touched on light bulbs much. In general, I believe this would be more of a Bau Biologie question.
However, we did do some research in attempt to help, and this is what we found!
First, the term "full-spectrum" seems to actually refer to the type of light a bulb puts off, ranging from infrared to near-ultraviolet, and there are available full-spectrum options in CFL, LED and incandescent. It is worth noting that, like with greenwashing, there are bulbs that specify "full-spectrum" that actually do not include the entire spectrum and aren't much different from an average bulb.
That said, there does seem to be evidence that LED bulbs give off more EMFs than incandescent, in the form of "dirty electricity." Most research and writing confirms that LED bulbs do emit a certain type of EMF, known as dirty electricity, which is caused by products that transform the type of electricity flowing through wires into other types (from AC to DC) in order to provide lower voltage and use less energy.
If this is a concern for you, you can try halogen incandescent bulbs, which are clean, or look for high-quality, high-efficiency LED bulbs that do not use a transformer, as they are safer than traditional LED bulbs with regards to EMFs.
In any case, I would definitely recommend researching further into available lightbulbs and Bau Biologie for more information!
