I am looking for advise, I'm thinking of using only my HP E3614a power supply to power a 445nm 1w diode for first light.
I thought that I should use the HP because it has a ten turn current adj pot.
Is this suitable to slowly up the current and not spike the diode? Or do you guys think that I need to add a extra current regulator circuit in series like the lm338 or lm317 for safty for the diode? Are dedicated drivers any safer for ramping up these diodes?
