Abstract: An arc lamp holder includes an axially directed air duct containing a socket into which the base electrodes of a sealed beam arc lamp are inserted for making electrical connection to the arc lamp. An ignitor assembly which includes a toroidal transformer is coaxially mounted of and surrounding the air duct. The ignitor circuitry includes a primary winding connected in circuit with a charging capacitor and a spark gap element. The capacitor is formed by a plurality of parallel connected disc capacitors mounted in a circular array to form a relatively large storage capacitance which is discharged through the spark gap and primary winding of the transformer to produce a high step up voltage applied to the arc lamp for starting thereof. The step up transformer, storage capacitor and spark gap are embedded in a dielectric potting material forming an integral portion of the lamp holder assembly.
