Rebuilt 14-15-20W Ballast

Rebuilt 14-15-20W Ballast

Click to view full size image

Here is a generic 14-15-20w ballast that i rebuilt for some reason, even though i could have bought a new ballast for roughly the same cost as rebuilding this one (and it's not 100% done yet).

This ballast runs F20's at 350mA and F15T8's at 400mA (versus 300mA for F20's and 320mA for F15T8's when compared to its rusty counterpart).

Interesting that you can get any reasonable current from it when you insert the E plates from alternating sides. They gotta be quite loose from each other vs. how they were in the original assembly

I actually cheated a bit a put two layers of electrical tape between the E and I sections in order to get the reactance just where i wanted it (i should have used mylar tape but i do not have any on hand).

Old lighting is, and will always be, the best lighting.

Oh so the inverted E's (the ones that bypass the gap) are only the first and last ones ? - In this case the part that bypasses the gap saturates and this way doesn't have much effect anymore..

The electrical tape will probably compress over time from the heat and magnetic attraction, the ballasts I have taken apart had paper soaked in varnish although super glue will also work for a while.
