Hi Guys,

Here in Australia we can't get as much, and specialist lighting is hard to come by, which apparently is Metal Halide? :rolleyes:

Giesemann are really the only quality option, some unbranded probably chinese globes are also available, but I'd imagine quality control isn't as strict. Radium bulbs are pretty well extinct here in Australia, so unless any Aussie readers have any contacts please let me know!

So my question is what Giesemann 400w bulbs would be visually similar to halide? These bulbs are running on a pulse start magnetic ballast, the ones which originally came with the Giesemann Spectra here in Australia.

Thanks Guys,
Cal

What Giesemann fixture are we talking about? DE bulbs or SE bulbs? What are the bulbs you are running now? Can you please post a picture of the ballast that came with the Giesemann fixture? Please post a picture of the label of that ballast with the specs.
