There's several ways to check one is on your regular 110 outlet. If it reads below 125 volts you're likely OK. If it reads 128- 130 or higher I would call and complain.
The way you get the other voltage is by reading something like a dryer outlet, range, etc across the two hot conductors. That is two voltages each 125 volts but out of phase with each other. When each individual one is checked to ground you get 125. When checked across each other you get 250 volts.
Not to refudiate your post, I just don’t understand. All I know is flourescent light is very irritating to some of us, and now the government is telling us we MUST use them? What are we to do?
