Continued!..................

Now after you got the socket secured into the duct work,take the bulb out of the socket and take the foil tape and wrap the inside of the edge of the duct several times to try to build up a cushion for the glass tube to rest against also helps take up the gap between the duct and the glass tube because it isn't a perfect fit....................you can also use normal foil to help build up the base of the funnel.....................

Now take one end of the glass tube and wrap it with foil tape,go around the base of glass a couple of times to once again create a cushion for the glass where it meets the end of the duct! after all glass on metal isn't the best idea!.....................now insert glass tube into the duct end that you prepared just keep working with it until the glass tube fits nicely snug into the duct......once you do this.then wrap the glass and the duct together but stay close to the edge of the glass because you want as much of the glass tube being clear,try not to go to far down the basde of the glass,may restrict some of your light!................once you have both ends taped together with foil tape,reach inside of the glass tube and tape the inside of the tube to the duct that way you have a complete seal once you turn on your fan!......................Now we are half way there!.............

now we have cooltube hooked to the 1ft duct,as well have the light socket anchored inside the 1ft duct...............
