Ok a search on direct drive just seemed to confuse me even more.I often hear people use the term direct drive and each time it is said to produce a very bright Luxeon however with many risks involved.Can someone explain exactly what direct drive is?
I thought it was simply using a board with no resistor in place but from searching old posts I think this thinking is not correct.
Lets take the little Dorcy AAA circuit for example...I have used this circuit for many mods and usually remove the 1 ohm resistor.Does this mean this circuit is now direct drive?I am trying to understand the term and am also wondering just what the order is to control the current or voltage in a direct drive light.I know it has something to do with the VF of the Luxeon and I assume it also has something to do with the voltage and current of the power source but I am still curious.So what exactly is direct drive?...Is there such a thing as a regulated direct drive circuit?
Thanks for any help on this.
