What is the most simple way to create a circuit for a string of 5 to 10 high powered LEDs? I think that I want to run them in series to make sure I get maximum brightness.

I would like to incorporate a driver because the research I have done tells me this is the best way to regulate current and ensure that the LEDs won't over heat.

 

Could be as simple as a Meanwell ELN driver/heat sink/LED's in series..
More specifics can be provided once you give more detail..

Whats a high power LED??.. 30mA, 50mA, 1W, 3W, 5W, 1000W
Vf of LED's?
Input/Supply voltage?
Specific LED part number?
Mounting configuration?
Available space?
Forced air?
on and on...

 

There are limits how many you can run in series. My tutorial is about low power LEDs, but the basics are exactly the same...

LEDs, 555s, Flashers, and Light Chasers

For you, chapters one and two.

 

Didn't you know that LEDs in series are exactly the same brightness as single LEDs that have the same current?
