Im looking for a 5v 2A driver or self build circuit with current regulator with;


Constant linear current, no pwm

High efficiency, i can get 70% from a 10w resistor

User defined levels, so no cycling through strobe etc, preferably with resistor switching

Weight or size is not really a problem within reason

Cost within reason isnt either, aslong as its worth it


Thanks for the help,pete
