Even if your not new to the game sh@t happens..lol.
Hyper reds? The leds..730nm..are usually called far red. Most of their spectrum is in the IR range which is non visible light. There is normally some visible light emitted though.
The only led I know that goes by hyper red is osram ssl hyper red at 640nm...most companies call that part of spectrum deep red.
If a few are lighting then you know your supplying enough volts to test it. The ones that aren't lighting...if tested separately...are probably burned out. I usually can identify a burnt emitter by just comparing it to one that lights...you can see a color change of the led die..a burnt look...
Must have shorted it somehow when testing..
That's one reason I have used a killawatt to check draw instead of going further with a mutimeter. I didn't want to burn out leds figuring out the correct settings and placement of mutimeter.
I do still need to get to that eventually...but it hasn't been a necessity.
400ma is a low current with ir leds...they WILL be dim...the 730nm spectrum dosent need to be overly bright so it's not a bad thing either..it's just a trigger for flowering to my knowledge
You also need to meet the minimum voltage requiremt of the driver....19v. 8 at 2v would only be 16v. So you may need to add a few leds to the string to meet that requirement...whether another color...additional far red of same type....or a far red led that runs at a higher voltage. Maybe just one xml that runs at 3v or so will give you the little extra you need.
But...it worked running a little under the recommended voltage until you used the multimeter for testing. So maybe not necessary to adjust voltage on string.
The emitters that don't light sound like dead ducks...just replace those and you should be good. But it wouldn't hurt to boost the 15.54v your getting now to 19v with an extra led or two.
