Best driver for this led?
Well, i'm so new to high power LEDs,
My dad bought a high power LED on ebay http://www.ebay.com/itm/160584479457?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
The LED has the following specifications
Working Forward Voltage (VF) : 9-12V DC
Working Forward Current (IF) :1000mA
Intensity Luminous: 800Lm
The seller told me to use a DC DC converter for it. I will not pay $20 for one.
I've seen lots of sites about the driver but most of them has circuit made for LEDs which have a forward voltage of 2.8-3.6V.
and mine has a Forward Voltage of 12V.
So what will be the best driver for it.
I found this one but i'm wondering if this would work http://www.simple-electronics.com/2011/09/high-current-led-driver-using-fet.html
