Critique My Parallel Series Layout

I feel I have this down. Just wanted to see if anyone wants to tell me if it's right or wrong.
It's nothing more than a paint drawing and is pretty simple.

The drivers will be adjusted to 1A which should give each string of 12 600mA.

 

above my pay grade, but bump!

 

I should be more specific. And thnx for bump cosmo.

My plan in steps is:

1. Before taking the current 28 3W LED mod in my mh fixture apart I will adjust the drivers to 1200mA
2. Layout the current and additional 20 LED's, solder and wire the circuits as shown above.
3. Check each LED for short/grounding.
4. If all circuits are good I'll power up the drivers and check each string for 600mA at the resistors.

Hopefully they are all very close and I won't need to do any balancing. That would make it a whole new ballgame.


So if you happen to read this and have some advice, or if you think something is wrong please let me know. TIA

 

I just read up a bit on it out of curiosity and it looks good to me! Here was a nice little graphic showing pretty much what u did!

Just remember the reds blues greens and UV operate at 700 mA the whites are 1.3 A so make sure if you are having other colors not to burnt out the lesser powered LEDs

 

Well my expert opinion after reading 1 article on it!lol! Is that when you run in parallel it splits the power so if he's running at 1200 mA hell be pushing 600 mA a string! Now that's assuming the article was right and I can read! both stretches!

 

That is perfect. I just did something similiar with a 4.4 amp driver I have 8 strings of 9 leds (72) total. The driver is divided by how many strings you have running in parallel. In my case 4.4 ÷ 8 = 550ma per string of 9 leds. Every string MUST be the equal amout of leds though. Only difference in mine is I have a 750ma quick blow fuse as the bridgelux leds are only rated for 700max. This way really is the better way to do it. Less drivers less wiring less headache

 

I forgot I had posted this here.

Yeah it's all been figured out and the parts have been ordered. I'm pretty stoked about going all LED finally.

 

Congrats man, i love showing off the different lighting options, plus its actually cool watching the sunrise sunset effect! love them!

 

I shouldn't have said "all the parts". I was holding off on a Typhoon in case I punked out on the parallel. If so I was going to order two more 48P's w/ it. Now I go to order and it's OOS. LOL Hopefully they have it back in stock soon.
