the inline fans at home depot or lowes suck they come in all sizes 4 6 8 inch.the "vortex" fans are $$$ google them. lots of diffbrand names same type fan tho.Htgsupply has deals. i leave one side of my hood open attach fan and ducting to suck thru the sealed fixture at the socket end .at the same time it exchanges the air in my room cools the bulb and evacuates thru the chimney.same place the furnace and hot water heater vent to all hot sources.
