No transformer needed for LED.
If it had a transformer, it would light up the gaussmeter!

Very different from flourescent lighting which needs ballast transformers.

I suspect they are using a combination of resister and diode, since
there is no large amperage requirement.
My knowledge if electronics is not specific enough to design a circuit,
so I might be leaving out a capacitor.

Just remembered to test on the GS meter,
with the 18-bulb-LED off, the reading is 47, and on is down to 43.
So perhaps it does have a capacitor, like the GS filters.
