(2) no striker needed (usually comes as a form of a capacitor (round aluminium can with 2 legs, which creates a blue/purple arcing look inside the can when "striking" happens).

(3) more precise control of the current used than mag ballasts.

Because of all of these, electronic ballasts (run on high frequency), when done right, can make those tubes lasts extremely long...

It is not impossible for those typical T8 tubes to last >10,000hrs or more under average operational conditions.

Oh BTW: mag ballasts relies extensively on pre-heater hookups. If any of the pre-heater wiring inside the tube becomes open, the tube is essentially "toast" and cannot be used.
Electronic ballasts also eliminate the 60hz flicker which has been claimed to give some people headaches. The buzzing associated with magnetic ballast is gon also. I don't think even make the magnetic ballast anymore, raw material costs more than the boards in the electronic ballasts. Manufacturers are always trying to reduce the amout of raw material in thier products, have you noticed just about everything is lighter than it used to be?
