    Hi people..

    My dad had some spare glass so i commandeered it to make a new T5 hood for my 3ft.
    Here's a pic with one of the two tube rails placed..

    So far my dad has helped me big time with the lid.. (pics coming soon)
    All the ballasts will be going in their own box relocated below the tank.

    Looks nice. How you going to rest the top on the tank? Also since glass is seethru dont you think the tanks going to blind you? what about reflectors etc?

    Some of the main T5 wires can't be more than say 1m. If they are you will pop the ballast. At least this happens on my VS ballasts.
    Where did you get the tube holders from? Would love to get my hands on some.

    Thanks Mekaeel - most of the glass is 5mm and some 2mm for the tube holders(all i could find):whistling:

    Sentari - The outside will be coverd in 2mm mirror and there are "stays" (lil pieces of glass under the rim) so that there's an overlap of about 10mm all-round.
    The way i measured the tube holders, the width is perfect for a "standard" reflector over all 6 tubes. Gonna try my hand at making some individual alanod one's in future.

    Ta Prodigy - Agreed dude.. that was the vrou's.. (mines are in the lil white bottle;))

    Marius - Thanks for the heads up dude.. Tube holders are just a piece of 2mm glass with the t5 endcaps siliconed on.

    Personally i wouldnt go for mirror. Have you seen what happens with saltwater and mirrors? They start pealing off and looks like rusting. Why not paint it with black acrylic paint or something like that?

    Sounds like a gewd plan and yes i have seen what happens to mirror (yeesh).
    I thought if i sealed the edges of the mirror with epoxy resin it would be cool..

    Heat factor has come to mind but the back is opened might just mount some low V fans into the reflectors. Any suggestions??

    @Loki sorry to put a damper on your project but your globes are far to close together. The heat produced will destroy the globes let alone the glass cage that contains them.

    Take a tip from the pros that build aquarium light fittings and look at the specs of how many T5 globes they build into a fitting. So do a little more homework. You can start here.

    thanx for the heads up Nemo.. having read the doc:
    I quote:
    "These models have
    adjustable speed fans, that
    change refering to the
    internal temperature."

    Can't be THAT difficult to replicate in this instance..
    I agree with you on the spacing tho, hence the next order of business will be the heatsink / reflector to help with the thermal dynamics.
    Fortunately this is just a prototype so whatever i (we) learn from this can be perfected later on.
    Waiting to get my hands on some alanod to do the individual reflectors.:).

    As they say "Nothing ventured nothing gained"..;)

    You can get the adenoid from a company called ARCONA in randburg. They import it. However if you want a off cut for your project give me a pm and i will give you some.

    And i will give you a heads up on how to make good reflectors.

    Help me out here guys..:
    Is 12 tubes over-kill for a standard 3ft tank or not?
    My understanding was "the more the merrier" when it came to lighting?

    Any opinions?
