Couple things Nick, from my understanding. First is the switchmode
power supply they use to power the LEDs, which naturally has to be a
high efficiency supply since these changeouts are justified on the basis
of energy savings, and have to comply with federal (ITE) standards. The
other factor is you just know how the installations are going to be done
- the contractor will use the existing wiring which was installed when
the old incandescent lights were, and that means unshielded wire, not
even twisted pair. In other words there's a noise-generator connected
to an antenna that happens to be draped pretty much overhead as you're
sitting underneath it.
