I already have existing 4" duct I would like to use with a new 350cfm 6" Inline fan I've bought.

You will need a 4"-6" adapter from HD in the air conditioning section.

i wonderi if it will cause ill effects on the light fixture since it's a 4" vent hole. i know it will probably increase velocity and noise but it would just be easier to use what's already there.

won't cause any ill effects on your light - if anything the fan would be the thing taking the efficiency hit - but even that would be negligible. i find that very tough - aluminized duct tape (the sticky kind - not the metal kind) makes excellent adapters if you don't want to buy any.
