Hi! Hope all are doing well.
I am currently in the process of making a solar powered DIY light and for this application I have chosen a CREE XP-L HI LED. I have my LED's, my power sources, etc. However, I am struggling to determine how to power this light to my desired output. All I know is that it's max output is roughly 1045 ish lumens and has a drive current of 2.95v @ 1.05A (whatever exactly that means besides what it explicitly states)
For my application I need 254 lumens so about a 1/4 of the max output. How do I figure out how much power is needed to get this output? Is there a chart somewhere I need to pull out? Also is it voltage I should be concerned about or Amperage? I was told higher voltage makes the LED put out more light but from my understanding it's Amperage that determines that.
Either way this should help me determine which driver it is I need to get.
Thanks to all the folks on CPF. You guys have always been a life savor.
