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

Denny is correct about the “hash” that the LED lights can put out which can interfere with our radios by breaking squelch continuously.  This does not seem to impact our ship’s radios or handhelds if you are a short distance from the hangar.  In my case if I am working on our radios I turn off the LED lights and turn on the large round non-LED lights (on/off breakers in the SE electrical box).

That being said after the hangar door is open we should make sure to turn off all hangar lights.  It saves energy!
