{"product_id":"prefocus-torch-bulbs-3-5v","title":"Securlec Prefocus Torch Bulbs 3.5V","description":"\u003cp\u003eThese Securlec prefocus torch bulbs are 3.5V replacement lamps for hand torches that use a prefocus fitting. A prefocus bulb has a flanged collar that holds the filament at a set point, so the beam stays centred in the reflector once the new lamp is in place.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePrefocus torch bulb design\u003c\/li\u003e\n\u003cli\u003eRated at 3.5V\u003c\/li\u003e\n\u003cli\u003eMade by Securlec\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSecurlec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e3.5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003ePrefocus torch bulb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWhich one do I need?\u003c\/h3\u003e\u003cp\u003eCheck two things on the old lamp: that it has a prefocus collar and that it is marked 3.5V.
