I searched every where on how to upgrade my Eclipse 3 hood to give out more light on the cheap..

I saw the retro fit kits but they were not cheap.

AHsupply kit was not too exspesive $45 plus shipping

then i found ODNA (over driven Normal Output)

So I went to Home Depot and bought a Sylvania Ballast for $15 and some new fangled push connectors $2, and a three prong power plug $9.

Now out of my eclipse Hood I should be getting some were around 70 watts or a little less, on a 29 gal tank.

This is my first plant tank so 2 wpg should a great starting point.

Just need to find some good cheap 24" bulbs to put in, since the ones in now are pretty old and turning black on the ends.

sure thing..

basically take it apart, unwire the old set up and wire in the new ballast..

I also added some vents since it will get hotter.

The link is in the original post, look up

fixture looks exactly the same as it did before the upgrade except for the two extra holes in the lid.

I cut the original ballast off and connected the new ballast to the end of the cord and from the other end of the ballast connected to a grounded AC plug.

Should work fine in the 18" if you want to fit the ballast in the hood it would depend on which one you get.
