i recently got this torch to use as a host for my 1 Watt 445 nm handy
DealExtreme: $24.69 Aurora X-06-3 Cree P4-WC 120-Lumen LED Flashlight with Assault Crown (3*CR123A)
I've tested the LED driver of this torch with a dummie load(5x N4007,1 ohm resistor).It gives 1,090 amps and the voltage across the dummie load-including the resistor is 5,3 volts...
I'm thinking of using that driver to power the diode...
(the batteries used are 3x CR123 rechargeables 3,7 volts nom.(4,1 volts max),880 mAh)
would it work?:thinking:
P.S. the driver was a bit overdriven,as the manuf/er suggests 10 volt input voltage for 900ma current.Probably is a linear current.When input voltage is 12,3 volts the current goes to 1,090 A.....
