Building a light from a light advice

[reefwars]

was a piece of cake easier than installing a plug in the wall, makes me kinda mad that theres so little to these lights. when i was done i taking it all apart i used one of the three metal halides and installed it into its own "rough canopy" to see if it works and it did.


now my next question is the actinic's that were with the light are 4x3'x39w can i get 18" 39w bulbs and can i use the same ballast and what not from my three footers to make a 18" t5-ho??????

Take the #s off of the ballast, input into google and see what comes up.
Should be info somewhere on this.
