    Hi There,

    After going round in circles looking at over tank hanging lights ive come to the conclusion that for my tank (100x40x30) im going to have to spend over £150 to get average lighting 2x39W t5 or £400 to get high light with a 4 tube t5 system.
    LED is the same, £400 ish for two small circular units or £400 ish for a long luminaire type.

    in not too keen on that so am looking at a DIY option.

    i have a broken Juwel Rio180 tank with the 2x54W T5 lighting unit that is only a year old as i replaced it recently when the old one failed. now i'm trying to find a metal half tube that i can fix it to and make an overtank hanging light out of it.

    hard to describe but think of a piece of guttering turned upside down with the lighting unit fitted to the underside of it. although not plastic but black metal.

    the issue is i can get half round pipe but the diameter is too small everywhere i look, it would need to be 20 to 25 cm diameter at least to fit the tubes into and about 100cm long in addition something that comes with end caps would also be useful (am i asking too much!)

    does anyone have any ideas as to sources of such pipe.

    i have a vision of a black matt finish pipe on the outside, polished metal inside to act as reflector and a couple of bolts through each end to hold the Juwel lighting unit in place.

    thoughts on a postcard please......

    Hi all,
    You can use plastic guttering and gutter ends as the luminaire, I've used them a lot. Paint the outside any colour you like, and the inside with gloss-white paint as the reflector. The internal paint tend to discolour over time, but you can always paint over it, you want as smooth a finish as possible.

    Have a look at this thread <http://www.aquaticplantcentral.com/forumapc/diy-aquarium-projects/79213-h-supply-gutter-light.html>

    If you want a cheaper lamp than an aquarium one the "Lightwave T5 Growlights" are OK. They only come in 2 or 4 foot, but you get a 4 x 4' 54W fitting for less than £120 (and you can have the 2 inner, the 2 outer or all 4 lamps on).

    If you want a really cheap option, you could get some "Large Edison Screw" (E27) fittings and 550 SM LED bulbs (like a corn-row bulb but uni-directional, so you don't need a reflector). I've got some of these E27 550 SMD LED at the moment they seem fine, but I've only had them for 3 months. They were about £12 for 2 plus the cost of the E27 light holder (I got ceramic ones for about £4 each, but could have got cheaper) and mains cable.

    cheers Darrel

    Thanks Darrel,
    the main issue is i want to use the Juwel Lighting unit that i already have. that cost me a round £200 a little while ago and theres no point in wasting it. however its 18cm wide (2 x 54w t5 tubes 900mm long)
    the issue is gutter pipe isnt wide enough to fit the unit into. i need tube ideally metal but maybe plastic thats 20 to 25cm wide

    Hi all,
    Are separate reflectors for each tube a possibility? I'm not familiar with Juwel light unit, but could you have them as a "Gulls wing", mounted on the central ballast?

    I think some-one (iaquatics?) sells reflectors for Juwel units? Again don't know if they are suitable.

    cheers Darrel

    yes you can get reflectors, the issue is ive blown the budget on a new optiwhite tank, braceless and open top. new eheim filter, glass pipes, ada substrate...not bought rocks or plants or fish yet and then just realised i need another £400 for lights!!!

    a mate pointed out i have a perfectly good juwel lighting unit so why not use that. however its ugly so no good on its own unless i can cover it with a canopy of some sort.

    it would be a shame to not use it but on its own it would look butt ugly over a brant new opti white tank with glass pipes etc.. if i can put this into an inverted half tube all you would see is the tube so as long as its got a good finish to it it should look fine. hence why im thinking matt black painted metal tube.

    see what i mean?

    Buy some thin-ish aluminium sheet from eBay and fabricate it to fit the unit and meet your sense of aesthetics. Some sellers will actually do this for you for a small fee. It might also lend itself to fixings for over tank suspension.

    Tank is 100 cm x 40 x 30 deep. Would any of those be suitable?

    Either will be ideal James. It's down to you for choice. I think two tiles would look much much better and not over kill.

    I'll pm you now mate
