solar pir lights
Is this possible to make a 12Volt PIR & FloodLight from a 240V one?
I have a solar/car battery system setup, and want to run an outside Security PIR Light using 12 Volts. Is it possible to buy a 240V Security Pir Light (fairly cheap to buy), and change it to work with a 12V supply?
I can get 12V 50watt Halogen bulbs no problem, its the PIR sensor i can’t find. Does anyone know where I could get one from or if it is possible to change the PIR circuitry to accept a 12V supply as opposed to 240V mains?
Cheers
Absolutely not. The element that lights up has a certain amount of electrical resistance (ohms) depending on the voltage to be used. The resistance on a 12v is not proper for 240v and would immediately burn out when used.
