24 volt too 2 - 12 v LEDs

Using a pre made bridge rectifier for each leg of the Supply shown, diode share load. 
The inline resistance controls current from the transformer & the filter capacitor to the diode string, approximately 5 meters long.
This project used a standard heating system transformer & pre built bridge rectifier on a heat sink mounted to the sides of the transformer too save space and increase sinking of the diode bridge. Combined half wave output to make a larger current output @ 12 volts with a simple regulator too balance voltage.

Why the diodes on the grounded conductors, you are already half waving with the positive diodes, there are only adding inline resistance. I can only see this as a safety feature for when playing with a circuit live.???

Rich some time a bridge is a connection point this makes it easy to see in the real world PSU, and that is a great question. Thanks for the input.

I'm using this in my home lighting project, its cheep easy and fast to build also supply's large amount of current for long runs of LEDs
