Thank you for your detailed overview of how an electronic ballast operates, keep up the good work.

Thank you so much for this. Exactly what I needed.

[@franciswhite419]

what is the typical lamp drive voltage and frequency of these ballasts?

[@great__success]

it varies....check this table: amarokcz.wz.cz/img/ECG-T.gif

I have a fluorescent light that has an electronic ballast but the one lamp flickers on startup but only when the fixture is grounded any ideas? It used to work fine

[@thedavesofourlives1]

awesome thanks for the hard work!

Cheaper than WD40 is just to use kerosene, works in the ultrasonic cleaner as well if you leave the basket out.

Wait a minute I thought T8'S had no tare like T12's

[@opieshomeshop]

Potted in tar because they dont y ou want to spend a few bucks fixing these. They want to sell you a brand new one.

ELEBTRONIC BALLASTS ARE JUNK,DONT LAST MORE THEN 2 YEARS

[@great__success]
