    just wondering - in my hood I run 2 PC fans just to keep the excess hot air from the T5's at bay - I have noticed though that the electrical connections keep rusting and I must replace them every so often.

    So the question is is there any specific make or something similiar that won't need to be replaced all the time?

    Are you using connector blocks? Try insulating the connection

    no that part of the connection is fine - is is where the manufacturer "welds" the little wire to their connection on the motors etc. thats where is rusts off.

    Well, you can start by using 220volt fans that they use in kitchen cupboard/computer server cabinets, they are well sealed and all you need is two push on lugs to connect to the power and then you can some heat-shrink to seal the connection.

    With the pc fans and the problem you having try some silicone

    Let the fan blow in and not suck out this will keep the moist of the motor and wiring

    with these 220 volt fans - does it plug directly in to the main? You just add a plug and switch?

    Thanks for the input guys. - had a look at a LFS yesterday and ones they have for sale are just far to expensive!!!
