Not sure what the current limiting resistors are.
There are strips that are designed to be powered from a constant voltage supply.
They use on board resistors to set the current limit. That is not the case with your boards.
Your boards are designed to work with a constant current source.
Although if you are VERY careful you can save some money (with risk) and power them with a voltage source.
The key to doing this is the temperature and not exceeding the max voltage.
If the LEDs get too hot they will draw more current. As they draw more current they get hotter and on and on until the board burns up.
This thermal runaway process can take hours so you need to check the temperature of the strip occasionally for a couple of hours.
There is a similar thermal runaway process that takes place when you power two strips in parallel with a constant current source.
The current in one strip increases and the other decreases until most current is going through a single strip.
This type of runaway can take many hours to play out.
The safest way to power strips is with a single string of strips powered by a single constant current source.
Like using an LDD driver with each strip and powering all the LDDs with a single LRS.
I have some Bridgelux Vesta strips powered by 350, 700, and 1000 mA LDDs.
The 350 mA is warm to the touch at about 40° C.
The 1000 mA is almost uncomfortable to touch for an extended period of time at about 50° C.
The 700 mA is in between warmer but not very hot.
Do not exceed 50° C when powering with a voltage source.
