free stuff is always good. A few things to keep in mind:

there is no point in running all six ballasts if you need practice. I would do one ballast
until I was successful. Much easier to trouble shoot this way.

are the bulbs used? old/dirty bulbs can definitely make a difference.


make sure the right wattage bulb is mated to each ballast.

definitely research on here about electricity, overloading circuits, how many lights to use per circuit etc...

personally I would use the bigger fan to exhaust the can filter, preferably up into the attic.

Have fun and I hope that helps.
