Giesemann Fixture - Tridonic Ballast - Help Needed

[es355lucille]

I own a Giesemann (Original 230 series, I believe) fixture c/w 2 x 150 MH lights. I would like to modify this fixture to accomodate 2 x 250 MH.

I am totally assuming that these two ballasts will only run 150w MH bulbs.

Does anyone know where I can get Tridonic Ballasts from?

Or if there is one that would work in its place?

Try the DIY forum. You might get more response.

250W bulbs are larger and you will need to do more than just replace the ballasts.

good point GSMguy. He will need to replace the ceramic connections in the fixture since the connection points on the 150 watt differ from the 150 watt. That is if and only if they can be spaced enough to get them to fit.
