I know the LED component itself works off of the 1 to 3 volt range. However, we all know that there are "LED bulbs" that twist into a standard light socket. So obviously there is a step down voltage to it. And maybe an AC to DC conversion. Or even an AC 60 Hz to a higher Hz, depending on what the manufacture did.

With that said. There are LED tubes that directly replace the T-8 fluorescent bulbs. As noted above with the fluorescent ballast to remain. But apparently it could depend if it's the old magnetic or new electronic ballast. But there are LED T-8 style tubes that require to have the ballast removed all together.
