is it 1or 2a?
One without a driver draws about 2.7 amps I think. Bloke at work measured it on his p7 deal extreme torch.
the proper bike light i mean
bump?
2.8A if you want 900 lumens
is that measured or just "if you want 900 lumens"
does anyone know what current the driver pulls in?
Is the voltage draw 14.4v?
I heard the DX was around 2 to 2.4 ish amps
you need to push it to 2.8 to get near to the 900 figure and then also have a lot more heat and less runtime .
trout - the one you disassembled. what driver was in it?
Circuitry: Digital Regulated 1000mA Current Output
Brightness: 900 lumens maximum brightness
thats off their site /\
A P7 is 2.8 amp at 3.7 volt full power
4 dies each pulling .7amp 3.7 volts - wired in parallel so volatge remains 3.7 but amps are 2.8
That the max figure. It can be lower
so my 7-8v 5.2ah battery will last?
Should be good for around 4 hrs depending on what driver you are using and how efficient it is. If its for a DX light you need to find out what type of driver and what incoming voltage it will accept.
