Hello. Ive been playing with led's for a little bit but ive been using resistors and cheap cree xre's. not really good for efficiency
Im making a new portable floodlight so i can transport it and use it for working on cars or camping whatever. Perhaps even playing basketball at night if its good enough . Build is on the cheap, found a old ammo box and got a battery that looks good and fits perfect. Got a P7 from somewhere (dont know if i can mention on forums) and a nice backlit voltage readout from the same place. Ill attach a pic later if i can figure it out.
Basically, i want to run 1xP7 off 10 to 14.7v and i want to be able to dim it or for the driver to have modes.
I keep looking around for this but i get lost in a never ending reading session and never end up getting anywhere. Resistors are inneficient, Boost drivers unsuitable, small maglight drivers are too fragile (at least the ones i got were)
Can i use a voltage reg?
Buck driver?
Anyone got a link to something thats a good price and i can get in Australia without hassles?
Any other input on the project appreciated
Cheers,
Mike
