How there's no additional electromagnetic interference (EMI)/Microsurge Electrical Pollution (dirty electricity) on the sine wave when the voltage is being stepped down?

Do you know how there is no additional electromagnetic interference (EMI)/Microsurge Electrical Pollution AKA dirty electricity on the sine wave when the voltage is being stepped down? How are you able to avoid that? Perhaps it's there, but my meter only measures 10kHz - 100kHz, so if the frequency on the line is more than that, I can't pick it up. Do you know if it's there, but at a higher frequency range?

Our focus has been on ensuring that the light output (i.e. visible wavelengths between 380-780 nm) have complete spectral coverage and are emitted in a flicker-free manner, but unfortunately, EMF and dirty electricity have not (yet) been a focus area for our product designs and development. As such, we unfortunately don't have any data, measurements or specification-level guarantees regarding a certain level of EMF or dirty electricity that our bulbs would produce.

We have been receiving quite a bit of interest among customers who are concerned about EMF and do hope to put in some additional product development work to better understand the product design and power topologies needed to ensure an "EMF-safe" product and do hope we are able to make progress in this area in the coming months.

Are the frequencies of the light given by the bulb an actual representation of the visible light spectrum? I believe the frequencies range from near 400nm to 700+ish nm. I know typical LEDs will trick the eye into seeing warmth, but you're really getting a lot of blues and greens - I'm not familiar with the technology, only that it's becoming less popular in the eye health world. If CRI95, being the closest to the sun compared to any other companies that I've seen, means that the full spectrum of those frequencies are actually coming from the light bulb, then that makes me super happy! Can you elaborate? Am I understanding that correctly?

Our focus has been on LED emitter devices and the relative composition of the energy output and balance across this visible wavelength range, and this is where our products offer a strong competitive advantage. As you correctly mention, the CRI metric is a great way to make this comparison, and our products have a 95+ CRI rating, which does indeed suggest that it closely approximates natural light.

For additional information, please see our high CRI LED product page below:

Our understanding is that the superior visible spectrum quality of our LED emitters is independent of the EMF and dirty electricity concerns, which is a separate issue tied to the electronics and components used in the power conversion, and this is an area we have yet to invest sufficient R&D efforts into.
