  1. Just a warning - testing using a new PSU how not yet tested LED emitters do amperage wise on a Friday evening while drinking whiskey does not render viable results and renders precious LED’s dead. Learning is expensive.

      3K USD would be a little too much for me to break in gear over a Friday evening. I don't know how your laws in Canada are but here you really don't want to drink and drive, you loose your license for at least a few years if not for life and if you cause an accident its 10 years with no bail I think.

      Chinese workers are grateful and ask for more.... ;)

       

      LED strips typically have built-in resistors on the tape. But they require correct polarization.

      It's wiser to use too high value resistor, at the beginning, and have too little current, then decrease its value.

      @Sensei, they weren’t strips, they were Osram CSLNM1.TG one square milimeter emitters on MCPCB’s that I was testing for temperature to set the current accordingly on the driver. Unfortunately a new power supply unit that I got played some tricks on me so poof!
