Final DIY led ?'s

[NYC Joe]

About to start wrapping up my DIY led.
Everything laid out and soldering the strings.

Don't relly understand the MA output here.
I know if I do them higher. There's. Possibility of frying them.
But if I do them lower. Let's say650ma. What will that do?

Layout-
String 1- royal blue/reg blue/ violet LEDs, 13 total- this string needs to be run at 700ma? Cause of the violet LEDs.
Anyone have a multimeter that can help me dial this in?

String 2- cool white/neutral white, 13 LEDs total. Again this maxes out at 1500ma. What should u run this driver at?

String 3- colors Red/turquoise, few more royal blues, deep red, green violet again. Needs to be run at 700ma or lower. This also has a manual dimmer. Which is going the be wired up.

The other 2- will be connected to a reefkeeper alc. manually ramping etc.

Any things I should be doing to test the strings?
Def don't want the LEDs to blow up!

the reason they say to run the amperage at 750 - 880ma is so that you don't fry the leds. so if you have them running at a lower amperage you should be able to get more life out of the leds.

to far to borrow my meter...but someone can possibly help you out.

string 2 should be running at 750ma the recommended spec.

to test strings and leds. once again you need a digital multimeter. you need to put it in continuity testing. check for continuity to the heat sink/screws this is no good obviously. check for continuity from one led to the next to make sure you solder points are good. bench test before you install them over the tank.

just remember don't look into the light... lol
they are extremely bright so set your dimmer on low once you fire them up and gradually increase to make sure everything runs smooth. good luck.

Already saw spots with a simple aa battery tester.
Double checked all the + and - and blinded myself haha.

Ok now it comes down to:
Who wants to come over. I have beer!
