Sounds like you've had similar experiences.

The ballast seems fine.
> Fish tank tubes are a lot more expensive than household 40W tubes ~$3 :(These particular tubes are 30W, though I know what you mean about
aquarium tubes being costly. Replacing with LEDs is cost-effective
immediately. Long-term power-savings from LEDs would add-up nicely.

that are optimised for specific purposes / climate simulation.
To my eyes, these have a magenta tint.

It's not quite the same, but satisfactory for a few days.

about your bad luck!
I think a regular fluorescent tube looks a dull greeny-yellow in
comparison, though haven't used one of each long enough for a useful
side-by-side comparison of algae growth. ;)

IIRC, the fitting came bare, so I installed electronic ballasts from
Jaycar or Altronics.
