STEVAL-ILB008V1
therefore dissipates less heat than an
electromagnetic ballast. The energy saved is
estimated to be in the range of 20-25% for a given
lamp power. Moreover, an electronic solution
allows for improved control of the filament current
and lamp voltage during pre-heating, resulting in
increased lamp life.
