Just talking about how much power the drivers are actually putting out when on full blast is all.
Are you wanting us to test this? How would we do it?

Not right now. But you determine this when you do the voltage drop test across the resistors like we discussed before with the pots turned all the way up. That will tell you how much current (Amps) is going through each string. Then add up the amps for all 6 strings and that will give you your total output current in Amps.
The drivers are supposed to have a maximum output of 5 amps. With 6 strings that should equate to approximately 0.830 Amps per string. The goal of balancing the fixture like we talked about is to have all 6 strings running as close to equal as possible.
But sometimes those drivers actually put out more Amps than what they claim to. So that's why I was curious to know what they are actually putting out.

Yes I would do that before you put the lenses on.
The balancing goes back to when I suggested righting down on a piece of paper the forward voltages of each of the leds in each of the individual strings. I think before you guys told me that strings 3 and 5 were slightly out of balance with the other strings. But that was with the old drivers that didn't work. So I would double check and take care of that before you put the lights above the tank.

LOL...we just had that same conversation.....Danny said....OH YEAHHHHHH....I have to re-test all the stings.....hmmm...I should do that BEFORE the lenses
HAHAHAHA

Not a huge deal, you can still do it with the lenses on.
Well the lenses are not on yet....SO the next thing he is going to do is the line testing.....then the lenses

This is how I'd do it if I were you guys.
I would test all the strings (voltage drop across the resistors) and write that down for each string.
Then I would test forward voltages of every single led on each string and write them down.
Once you have those numbers you'll know which strings are out of balance. So you can look at your forward voltage numbers of each of the strings and figure out which leds you can swap around to balance them.
Once all that is done. I would add the lenses.

Set the meter on 20 for d.c. voltage for both tests. For the voltage drop test just touch the probes to each side of the resistors. For forward voltages of the leds just touch one of the probes to the positive side of the led and the other probe to the negative side.
For the drop test does the pot have to be on high?
AND IIRC for the FV test you said pot on high RIGHT?

Any results yet?
LOL...NO....He is at work today. I am thinking he will do the testing tonight when he gets home.
Then he is off for 2 weeks, BUT then Muzzle loading season begins
SOOOOOO we shall see what gets done....LOL

WOW finally had time to read through all 21 pages and i must say again.... WOW that looks amazing. Cant wait to see this over your tank especially since im planning to build one sometime in the next couple months. This may change the number of lights i use on my tank. After you get it hung and adjusted im interested to see if you would change anything if you were to do it again (numbers of lights and/or colors or anything else)

Once it's ready to go on the tank I can loan you my spare PAR meter if you want to see what your old and new systems are doing.

HMMMMM...what a thought....LOL.
IDK anything about those things....we shall have to talk about this further when it is near time

WELL....It seem muzzleloader season has taken precedence over my lights
Maybe next week we will have something to talk about
That's OK!
