Can someone help me with a couple simple conversion questions. I'm pretty good with electronics, but new to LED lighting. I read over most of these postings but could not find the answers to my questions.
I'm trying to convert a (3) cell flashlight over to use LEDs so the batteries last longer. I want the light brightness to be very similar to the existing PR3 bulb, which is rated at 3.57 volts and 500mA.
I'm trying to add about 50% battery life , but don't want to suffer on light.
I can handle the assembly of the circuit. I don't know which LED's to use or where to get them.
Questions:
Which LED should I use? (I want white light)
How many should I use to equal a PR3 bulb?
Where can I purchase them? (Radio Shack?)
Is one LED solution lower cost than the other?
Thanks
PS: This is a great message board. I just found it tonight. I thought I was the only flashlight nut around. I't good to know I'm no alone.
