Not sure if this is the appropriate place, or something like DIY. I have purchased 6 of these light bars from Amazon https://www.amazon.com/gp/product/B074NX7H1K/
The power supply is 6A and each bar takes .3A (4W / 12V). So the power supply should be sufficient.
I know that wiring in parallel each light will get 12V and reduce the current.
The light bar itself seems to be a set of 24 LED diodes with a resistor (hard to read the ohms through the frosted plastic) every 2-3 lights.
My plan is to wire nut them all together directly to the spliced end of the powered source, with a separate run for each light. Alternatively, I might create 3 'feeds' and then wire them in parallel in a set of 2. As far as I understand that is the same thing.
Are there any problems going this route? Will this suffer from thermal runaway or anything? If it does, how can I calculate what size resistor I would need before each light bar? If I don't put in a resistor, realistically how much would this reduce the life of the lights?
Please note that I am a layman and can't really understand electrical diagrams, but I will try my best.
