This is really neat. I didn't know it's that easy to shield EMF from these lights. But their products are extremely expensive.
The bulbs look similar to the Philips IR bulbs that most people use. I wonder what the difference is with these and the Philips ones.
I have 3 of the Philips bulbs myself (BR125), but without the faraday cage they produce a field measurable 1-2m from the bulb. I'm assuming it's just the metal grill around the bulb that is preventing (low-frequency) EMF leakage.
yes just the metal cage will drop E fields to zero, .. and yes likely some Philips bulb that they use.
As long as your bulb is near-infrared..
I don't know what they do for M fields and how come there are none, but I never measured a bulb for M fields to see what's there. They say no M field in front, but there is on the sides and behind.
