DIY LED assistance

Remote troubleshooting is pretty tricky on someone else's setup. Not knowing what type of LEDs specifically are in the string etc. Could simply be one of the LEDs on the way out causing the string to fail after things warm up a little.

DIY hardly worth it any longer with prices of commercial units coming down.

Can you give some info about the drivers you use and the general setup.

I'm using HLG150H-48B for those strings. Three strings in parallel that are balanced and running at around 1200mA. XP-E royal blues. I've got resistors and fuses protecting each string.

Hello

@mseepman what you described is straight forward. Not suggesting we can find the solution here with remote troubleshooting but a schematic can help. I have my whole place wired with 0-10V controller + Meanwell drivers and sometimes it's difficult to see visually think what goes to what.

First thought came to my mind is when the light don't come on do you have any meters to check if there are any voltage across the Meanwell terminals? Next is do you have anything at the 0-10V control?

Those are both excellent questions that I have not investigated. I will try to climb into the cabinet this weekend to see. Was very frustrating recently as they have gone out more quickly than usual each day.

Hello

Hope that helps. Usual disclaimer. Make sure you have your meter set to voltmeter and not ampmeter before you use it.
