Do you always need a buckpuck for high powered LEDs?
I want to power a Cree MC-E
LED with a 12 volt 5 amp/h SLA battery
. Most of the time you have to use a buckpuck
(an LED Driver). Do you always have to use a buckpuck? If I have a 12 volt battery and a 12 volt LED like the CREE MC-E, then I don't need a driver, right?
