    Default fan cooled light push or pull

    this topic is so miss leading on hps fan cooled lights.

    witch is the best way ?

    <<FLITER>><<DUCT>><<LIGHT>><<FAN>><<DUCT TO OUTSIDE>>

    or

    <<FLITER>><<DUCT>><<FAN>><<DUCT>><<LIGHT>><<DUCT TO OUTSIDE>>


    last time I tried the light I tried it both ways and don't think it made any difference if I remember right.
    but it was in the summer

    this is how mine is setup
    <<FLITER>><<DUCT>><<LIGHT>><<FAN>><<DUCT TO OUTSIDE>>

    I would personally go with - <<FLITER>><<DUCT>><<LIGHT>><<FAN>><<DUCT TO OUTSIDE>>

    But I believe I read somewhere that the most ideal way is to have cool/cold air from out of the tent, through the cooltube or cool system, then outside but I don't completely know how it works.

    I thought it would be the best way as the heat from the light can only go to the fan and then the fan creates a vortex like a tornado and sucks all the heat out.

    I think that if the fan is blowing from filter end it can get heat trapped inside the light area from the turbulence of the fan.

    if I am wrong someone please correct my way of thinking.

    You can have your filter at either end of the duct but make sure that your fan is before your light, as you don't really want the hot air from the light going through the fan

    I blow through my light .

    Make sure bulb socket is facing the blower . You dont want dust and grit hitting your bulb head on . Plus cooling off your bulb too much sucks up more engery


    Look at my set up

    You will see a significant reduction in temps using this method I'd say

    That is exactly how it should be. Your air cooled hood should be on its own fan. The extraction filter and fan should not be connected to the air cooled hood.
