Overdrive T8 Question
Ok, so I get the basic premise for overdriving a fixture. I have two 2 bulb fixtures I could break one down and add it's ballast to the other and run both wires from each ballast to one bulb. And then both wire sets from the other ballast to the other bulb. Giving higher light output in the same footprint.
However, that now leaves me with an empty fixture. Considering cost, to continue to buy cheap $10-$15 fixtures and piling up fixture carcases once I remove the guts, could I just buy a 4 bulb T8 ballast and overdrive it to the empty 2 bulb fixture? I see some online for as little as $4 and it would eliminate my extra fixture carcas problem.
I certainly have more room, but essentially for $4 I can increase the power of my current 4 bulb setup by 50%. Seems worthwile to me. Do I run the risk of having the ballast not fit in my current fixture? Are they all pretty much the same uniform size?
