Use it with:
HPL-N 250W, HPI-T 250W, etc.
Impregnated electromagnetic copper VSAs for use with an external semiparallel detonator for CDM, CDO, MH, HPI (Plus) and SON lamps. PHILIPS BHL 250 K307 230-240V 50 / 60Hz can be used with 1 lamp in combination with a igniter which is the same (power specifications) as the connected lamp. For example, you can use the SI51 igniter to connect to HPI. For HPL (-N) no ignitor needed.
A complete system to light the lamp requires a Igniter, Ballast and a 12uF Capacitor.
