I've got so much going on right now, it won't happen right away. But I will keep that in mind! This winter I should have some time to play around with some new ideas and lights. Thanks again bro, in a few sentences you substantially increased my very limited understanding of how these things work.
Mine, too.
Is this because the 3590's have a slightly less Vf at lower currents?
is it because one uses a better case maybe?i seen some of them are plastic,maybe its for the ip rating? most of us do have alot of water sitting about in the grow.
I can only speak for myself: knowing nothing and following in the footsteps of wiser more experienced builders, I did what they did. I believe in his awesome chart, Supra gives a breakdown of maximum cobs-per-driver using HLG as the example drivers. That's what I used to make my decisions.
Where is there a new chart?
It's probably because the ELG drivers are a recent addition for Mean Well and most people just copy what was used by SupraSPL. Indeed I'd rather have had ELG drivers because these are Dim-to-off. No need for relays to deal with inrush.
Water cooled COB LED was my rationale.
Both have IP67 ratings. Its just because the ELG is brand new and harder to source.
good eye! thats a pretty serious "footnote"
If you have a 220v hookup it may be a decent budget choice.
