    im worried about heat though. what are the negative effects of heat on my light unit? all the ballasts and lights are in one sealed unit.. there isnt much ventilation here.. i wanted to add some fans but i got zero space :( and im reluctant to drill some holes on the side of the unit :(

    let me ask our local scientists :)

    the lifespan of your bulbs will be affected and the life time of the ballasts.

    RC helicopters, now you talking haha! This is a really cool build and looking forward to the end result. If you can find a fan where would you be looking to place it?

    Go have a look at a decent RC shop for some fans used to cool brushless speed controls, I'm sure they should be about the right size.

    thanks dude!

    im going to drill 2 holes at the back for the 2 fans. or maybe it will only be one fan.. im not sure.. also then i have to get a inverter or something to run it on 12v.. or i'll have to rig it with those multi AC plug thingys..

    this really messes up my plans :p but on the good size i do see they make 3cm fans.. but i hate buying internationally. takes so long to receive it. anyone know where i can get these fans?

    Aah I see, have you phoned any local RC shops or computer hardware shops? You get little laptop holders with cooling fans on them you might be able to use. Not sure what size the fans are but then again 3cm is damn small so they'll prob be too big....hmm. Ill do some googling and see If I can find anything.

    Look on your old graphics cards. Their fans are normally tiny.

    You could maybe do a rechargeable 12v battery supply to the fan then there are no extra wires coming out of the canopy. Just not sure how long the charge would last.

    Hey dude, if you don't come right with the small fans up there send me a whats app and I'll see what I can organize. I should be able to get 1 - 1.5 inch for you.

    From Wikipedia: Cooling solutions for electronics or turbines usually use high thermal conductivity materials such as copper, aluminium, and silver to cool down specific components.

    The aluminium will carry the heat away from the lights and ballasts the question is where it is going to carry the heat to? Glass is also a good thermal conductor so it may transmit the heat to the tank. You can try install some fans to circulate cool air over the frame to carry the heat away but I have no idea how well this will work.

    I would run the setup for a few hours and see how hot it gets before taking any further action. It could be that no additional heat sink is needed.

    +1

    With all that aluminium around you might not need any additional cooling.
