Using 200w 6-55vdc boost Converter

Real quick question folk may sound stupid but here goes I am thinking to run 4 boost converters to supply 30vdc to 4 COB LEDs from a 7a 6-55vdc boost converter power module will this even have a chance of working I think it will but wanted some input from my folks here trying to use this module will this work? To supply 4 12vdc rails to power 4 of these

So I take it this will work since no one said it couldn't, thanks
