It delivers the high-voltage starting pulse an HPS lamp needs to strike, then drops out of the circuit once the arc is established. A lamp that will not start on a known-good ballast and capacitor is the classic sign of a failed ignitor.\u003c\/p\u003e","brand":"Advance","offers":[{"title":"Default Title","offer_id":50298402865389,"sku":"BC-LI501H4","price":21.75,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nls-us.com\/products\/advance-li501-h4-hid-ignitor","provider":"National Lighting Supply","version":"1.0","type":"link"}
