I have a speed controller so have turn it down so I should swap fans ? And put the fan at the end of what tube ? So have the fan at the window sucking air out ?
I'm in taking fresh air from the window at the back of the room from the left side of the window and exhausting air out the right side, so it's more use putting the exhaust ducting above the reflector than at the bulb?
