Thanks also to Petr for Work.
However, John, I will mention that all this conversion to LED does have its pitfalls to the Aviation band radio communication on the field, especially around the hanger.
This was well-noted in 2020, the hangar lights create much RFI ( interference ) that caused the SSI field radios inoperable until hanger LED lights are shut off.As we electronic engineers (me, EE) realize, the switching power supply converters used in LED may not be well-shielded enough, and can radiate much electromagnetic interference to AM- modulated radio bands, like VHF Aviation band.These conversions should not affect the SSI WiFi system at 2.4GHz and / or 5.8 GHz
