would it be possible

I have a 48" odysey set up for 2 250 watt halides, 2 96 watt power compacts and 2 65 watt power compacts. Is there any way to switch the power compacts out and put T5s in there instead? What kind of ballast and bulbs would be good for the Halides? Just wondering because our ballasts blew up,

 

probly a PITA. might be better to shop for ballast of ebay. Ive done that twice already, but did find exact fit one plug and play. just measure your old ones and you can find replacements that way. you could upgrade the pc bulbs to uvl brand like me. much much better.. same materials used in there t5 bulbs. reekgeek.com carrys the uvl bulbs w/internal reflectors.

heres a oydessa replacement 65w x 1 ballast I used:

heres a 96w x 1 ballast:

make sure your unit has individual ballast for each bulb. some have 1 ballast for 2 bulbs if that the case you'll need different ballast 65w x2 or 96w x 2..

also make sure the wires going into the wire harness (that connects to bulbs) are in there snug. mine were loose, the second time around and I thought I lost another ballast, but it was just shorting out. give it a try before you buy..

 

Odyssea has cheap ballasts and they don't last very long, I ended up replacing all of mine, I steer clear of that brand now.
