Point blank: Need to cool 2 x 600W lights using cool tubes. Is it possible to use the same pre-filter intake for the room, shoot it through the lights and have it exit all in one duct?

Planning on using an inline fan after the pre-filter, before the lights + 350cfm exit fan + carbon filter.

Do I absolutely need 2 sections of duct work and 2 main fans?
