modifying my 48" coarlife

OK i have a question about the product mentioned in the title. It comes with two switched but only plug to go into the wall and i was wondering if there was anyway i could make it have two outlets two where i could controls both stes of lights with different timers? I want to do this because i want to run two bulbs all day long and for 2-4 hours of the day i want to run the other two along with those. Since i am not always home i want to be able to do this with two seperate timers. Is there any way i could splice into the cord or something like that. If you have any question please let me know.

Couldn't you remove the stock ballast and add 2 Work Horse 3 ballasts and two power cords. There are wiring diagrams on Fulham's site.

I saw a post somewhere of somebody doing this on a tek light I believe. The unit was wired with one cord going to two switches. All they had to do was run a second cord and wire it up so one cord went to each switch. Pop open your coralife and you'll probably have the same thing. As long as there are two ballast you're good to go.

Yep, as long as there's a second ballast, you could probably look up the wiring schematics and figure out how to do it yourself.

All you need is an extra grounded power cord and possibly another set of wires for the ballast-bulb connection (probably not though).

Post up pictures of the ballast and we'll help. I've wire and re-wired quite a few sets already...and made some mistakes too.

shouldn't be hard at all, just need a cord, you can use an old extension cord(or new one) and just cut it to use.

This is assuming there is 2 ballasts, which 99% sure there is, b/c I've never seen or heard of one ballast that can be controlled like that.

Just open it up, look at how the existing cord attaches to the switch(both), then remove the wires going to the extra switch and wire them to the new cord just like the other one. Should take 10mins max as long as the fixture comes apart easy. You may need a couple wire nuts.

Found the page I was talking about.
http://www.njagc.net/articles/saveafewonteklighting.htm
You'll probably have to do it the same way as on that page but you may have to drill a hole for another cord. Not sure if the coralife has the cap for an extra cord like the tek does. Wal-mart will have everything you need to do this, and I believe they even sell replacement appliance cords so you won't have to cut an extension cord.

Ok guys I opened my fixture and this is what I have, I have four connection points, there are two ballast and this other little box that is coated in grade 8. There are two red wires coming out that the box with grade 8 on it both of the ballast have one black wire with a white strip down it and one regular white wire. There are four wire that come from the switches and of course the three wire from my plug and three more from the plug that I am going to add I am going to describe the four connection that I have and hopefully someone can tell me how I need to modity them

1st connection
One of the red wires from the unknown box
Both of the black and white wires from the ballast
And the white wire from my current plug

2nd connection
The other red wire from the unknown box
The black wire from the 1st ballast
And the wire from the lower left switch wire

3rd connection
One black wire from the 2nd ballast
The wire from the lower right switch wire

4th connection
The black wire from my current plug
Both of the wires from the top switches

Ok now I just need to know where to separate the wire as to make on plug control one set of lights and the other plug control the other set. So I need to know what wires to switch around and where to put the other three from the new plug I am planning on putting in there I posted a pic from the unknown box below



pic of the connections

With a ballast name/brand/model, I could pull up the wiring diagram and help. Without it, it'll be harder.

And in the diagram, it'd be helpful if you label the bulbs, the power switches, and the cord.

What you have.

What you want.


Sorry about my awesome photoshop skill, I don't have my circuit diagram program anymore.

First off, your mystery box is a 12 volt dc transformer for your cooling fans (almost positive). It doesn't matter which way this gets wired up so thats why both wires are the same color. Just make sure the transformer is wired to the switch for the ballast that will be on the most.

Wire all the black wires and one of the orange wires together. Wire one of the white wires to each one of the switches, one switch needs an orange wire too. Wire the green wires together and these should be attached to the light casing (ground).

it was a coarlife electronic ballast looked at a photo and it said model SPL- 255R-JS rapid start electronic ballast and i could label those things my program was messing up and as for labeling the bulbs they were not really connected to anything i was planning on doing all of the wire for the bulbs came out of one side and te other two i were using were coming out of the other side. At least i dont think the bnulb wires have to do with anything i am trying to accomplish

No you won't have to change anything with the wires going to the bulbs.

And I forgot to label the wire colors in my drawing. Blue = white wires, black = black, and green = ground.
