... From what I understand,fixtures that require electronic x-formers are those where size is an issue..You can get an electronic ballast to fit in smaller places,although the load/watts are generally alot less than it's cousin,the big,ol' clunky magnetic ballast/transformer which is not much more than an iron core with copper windings and a capacitor or two.. Being electronic,utilizes choke coils,and other small semi-conductor parts,thusly requiring the use of an electronic type dimmer control.Failure to do so can result in either x-former failure,or pre-mature dimmer burn-out.I believe hertz(frequency) has something to do with that here..I usually check with the manufacturer,or my rep at the lighting supply house I go to.. Good Luck!!
