What do I need to make a constant current driver for a 5w LED?
I have a Vollong 5w 350 lumen LED. I was told i have to use a constant current driver for it to work. I looked at some instructions on here of how to build your own, but it was for a 1w and he had 200mA of current. I am needing somewhere around 700mA and a voltage of 7v. Can anyone explain what parts i need to substitute to get this made? I'd like to just make one myself instead of waiting 3 weeks for one to come in. Any help would be appreciated. Thanks!
