Hi if anyone can help please do. My question is I'm after a module that needs 3v to 5.5v if I use a 3.7v will I get the same power in mw as if I used 5.5v ?or does the more voltage produce higher mw?

That depends on the driving circuitry. Voltage input will not matter with a constant current driver, but the modules (especially reds) will sometimes have only a current limiting resistor. In that case, increasing the voltage will change the current. In other words, if the circuit board has more than 1 or 2 parts on it, changing the voltage will not change the output power.
