Hello
Let me start by mentioning that I have little knowledge in this field.
LEDs I have: 12v 1Meter Rigid Double-row 3pin LED strips with 1.8A total draw (0.9A each row).
For some reason, they have massive voltage drop. With 12v input they measure 10.5v at the end of 1 meter and the lights seem noticeably dimmer, At 50cm it reads 11.3v. Is it normal? Wire used for testing: 10cm 2.5mm2(13AWG). Power Supply: 12V 15Amps.
I have to use the strips to light up my display cabinet(s), the cabinet has 6 shelves, each shelf is 25cm tall and 40cm long. I want each shelf to have it's individual light strip. So I will cut the strips in 40cm parts.
Now I have to find proper ways to wire the whole cabinet with minimum voltage drop, so the lights would be as even as possible. If you have any clue while considering the strips' huge voltage drop, please help.
I came up with three methods so far:
PS: I don't know how/where to make better presenting diagrams.
