My intent is to understand how to calculate the values of the components needed for my specific application. Save to parts list Save to parts list. Hi, I have been reading through the whole thread on Reef Central but I keep getting a little lost with all the ramblings from other peolpe. Your project is really interesting to me and i can do your project correctly. In your case the input voltage 42V and output load LED’s are fixed. Email Required, but never shown. The luminous flux of an LED is mostly linear, but at a certain point some of the current just leads to heat.
