24" to 48" t5ho retrofit can I do it.
 
I have an old reef fixture with 4x24" t5ho and a 150w mh and 12 led moonlights I paid 100 bucks for it a couple years ago but I really have no use for it(especially all the actinics)nowhttp://img.tapatalk.com/d/13/01/03/qyqyna2a.jpg

I have a 72g tank with a dual t8 shoplight fixture over it. I need more light the t8's are not cutting it.

I have no money to put into this project
But I do have some 48" t5ho bulbs

Can I use the parts out of this fixture to make a dual t5ho 48" light.

This will just be a temp light until I can afford a ray II, I don't want to put any money into this project. I have all the nessecary tools soldering iron, but connectors and a spool of 16g wire.

I'm assuming there's 4 ballast? For the t5's? Would I have to connect 2 to run a 48"?

I have no clue how this stuff works lol
Any help would be great

I'm no electrician, but just at a quick glance, I would probably say no: I don't think the ballasts could handle the jump to a 48" lamp (more than doubling the wattage per lamp). I could be wrong, though. Hopefully someone else can help you out.

Bump anybody have any ideas

why not hang the metal halide and let it light the tank?

You could take it apart and see how it's wired. If each set of two bulbs are wired in series, basically then say each bulb is 20w, then it's shooting 40w through the whole system. Remove tw of the caps go end to end it would end up at 40w (numbers are just an example). It just depends on how it's wired. If it's in parallel, it probably won't work, if it's series, it should.

Should is the key word. lol.

That thing sucks a ton of power, and it's a 48" tank so I would have to hang it pretty high. I also would have to replace the 10000k bulb with something more suitable for a planted tank(I'm broke)

So if I have 1 ballast per 2 bulbs I should be fine running 1 48" bulb off each ballast?

The theory is sound. I of course would take it apart and my multimeter out and things like that. Telling someone over the net it would work without ever seeing the inside of it, is harder to do.

try hanging it 14 inches above the tank and just see what it looks like
10k will still grow plants actually

just stand on a stool or something and plug it in just to see if its feasable.. it never hurts to try

Sethjohnson30 01-24-2013 12:02 PM

I'm not gonna mess with this old thing.

I ordered 2 20w 7000k led floodlights, and 2 10w 10000k led flood lights. I plan on running these alongside the dual bulb t8 shop light I have over the tank.

I think I will just toss that light on cl.
