Lux

Sorry for the double post I didn't think the first one took. I bought an LED light(link) that is listed for a FOWLR tank. I was wondering if I doubled the lights would that double the LUX or is LUX dependant on the output of the LED itself and not the amount of LED's. I would like to keep soft corals but I don't know if these would provide enough light. Thanks for any help.
