Posi,
How do those LDD 1000's get power - are they wired in series with the COBs on the DC side of your COB driver? How do you know how many LEDs can run off one LDD? Looks like 52v max, but is there a watt limitation for the LDD, or is it based on how many 'extra' watts you've got available on your main driver? I'm trying to wrap my head around how the LDDs work.
I'm ready to order parts for a 3 - Vero 29 3000k light driven by a HLG-120H-C1050B. Since the driver can run 4 Vero 29s, I've got some watts to spare, and would love to run 4 - 3watt deep red leds at 500mA, mounted between the COBs. Would the LDD work for this? Will dimming the HLG cause issues with the LDDs? Sorry if I ask too many questions, lol.

I have a 12v 2.1a dc power supply for my fans. It was only using about 5w so I just wired the LDDs into that supply. The uva consumes about 9w, the far red about 5w. Worked out great so far

The specs in the datasheet say how many volts they can run. Than you need to stay within total power rating. My case only strings of less than 12v no more than 25w total.

Haven't checked but seems the voltage rating will keep watts in check. In the case of a 12v 250w dc supply for example, it would be capable of running 5 LDDs at 52v at 1a....or 7 LDDs at 52v .700ma....each equalling about 250w.

No worries...answer what I can. I'm not a expert on electronics but this is my understanding.
You could run the reds off your hlg at 1a or build a parallel circuit off of your serial to cut the power in half to .500ma...haven't done it but theres a post somewhere in the forum with a sketch. The LDDs are different...they are made to run off a constant voltage dc supply. Not sure if you could use them with a constant current driver but it dosen't sound right..
The LDDs have a wired and pin out version. The wired is a bit easier but I think you could still solder leads on the pinouts. They are pretty cheap and easy to install....give it a try
