For the sake of this internal monologue let's say we want to run a four Cree CD bin 36V 3500K 3590 array and our driver will run on 120V mains. Let's say we want to both veg and flower under this array.
There are several HLG drivers that will run them:
120H-C1050
185H-C1050
240H-C1050
185H-C1400
240H-C1750
240H-C1400
320H-C1400
320H-C2100
Lots of driver options just in the Meanwell line! Some will just get by and some have lots of headroom. How do we determine the best driver for a given set of parameters rather than just choose one that works? We know that fV changes with iF. We know that there is a driver efficiency drop when dimmed and a resultant COB efficiency increase. At what point is the efficiency drop/increase optimized? We know that the harder we drive the COB the higher the Tc runs which affects COB lifespan and output. At some point there will be optimal overlap of all of those parameters working as a whole; the sweet spot of power consumption, luminous output, heat generation, lifespan, etc. But what if we wanted to design based primarily on thermal efficiency, or maybe maximize COB efficiency? How does it change given 220V? What if we score some sweet DB bins?
This is just idle curiosity. I've already designed, built, and installed my own system. Somebody smarter than me and with more free time should design a program matrix that takes all of the variables into consideration to derive the sweet spot given any COB/driver configuration given the primary design goal. Hahaha.
And... GO!
LOL
