DIY CREE LUMIA fixtures and apex
Hey guys, I am hoping someone can shed light on this for me.... as the title suggests I have cree lumia DIY led pucks. 4 of them over my 35g cube, yes it is a crazy amount of light...I have them all hooked up through a storm controller, however just bought an apex and I am wondering can the vdm module be used in conjunction or by itself to control these pucks... from what i can tell the vdm only has 4 controllable ports but each of my pucks has 5 channels, so would I need 2 vdms? Or can the apex control it through the storm?

Sorry don't know much about the Apex BUT do know you need a converter board to "translate" the Apex 0-10V analog signal to a 5V PWM signal.
Storm would not be involved in any way.. |

No they are 0-5V..
Other Meanwells are 0-10V (analog or PWM) like the ELN or LPF drivers..but the LDDs are 5V

Stepdown you mean?
AFAIK the VDM is 0-10V analog.. I have seen adapter boards to convert 0-10V analog to a PWM signal (5V) This is the first I came across.. https://www.stevesleds.com/Aquarium-...ess_p_183.html

Okay I have ordered the step down transformer thing-a-ma-bob from Steve's leds. No clue when it will get here.. but excited for it.. next question...
Do i need to get a vdm module? Or can I use the 4 variable ports on the brain in the time being? I don't currently have any pumps I can control with them. If I need a vdm that isno biggie, I have time on my hands waiting for the interface anyway...I havea stormX controller I could use too, by having everything controller through apex seems so much easier. I am going to get an icecap interface module for my gyre pump too |

I don't know exactly what fallback refers too.. but at this point it sounds as though I don't needed the vdm yet..

Since I was curious.. Seems the VDM module "saves" settings internally in case the main unit goes offline so to speak. |
