I have seen some "high frequency" ballasts that just
chop the 60 Hz so the 15% efficiency improvement is
lost. This is separate from the ballast loss, it is a
raising of the bulb efficiency by not allowing quench
to proceed as far inside the lamp. They label these as
HF but it is misleading. I cal
Actually I changed out all my fixtures last year and really noticed a
savings. I am only running 2 ballasts this year, not 4, but every little
bit helps.

Yes we are still working towards off grid. I am very pleased with the
numbers especially since I was using my table saw and other heavy tools for
a bit that month. Wind energy is of major interest to us.
Stevia dies at about 40F and even if kept warm, will die if it does not get

Hi Kim,
I think you're doing well. Still working toward severing the grid connection
to
save the trees? Sounds like you're making progress. Averaging about 16
kWhs/day.
You are now in the range where you have some viable off-grid options.
