400w HTI conversion

[Robert Saraceno]

Hi, I'm looking for to upgrade a projector to a HTL light source. I decided to start with my Eiki Nt-2 16mm projector for my first shot at it because it's easier to maneuver than my Elmo GS 800 I bought an Osram 400w/24 HTI bulb, like the Bauer p8 T400 uses, but I'm having trouble with selecting a ballast. Ideally, I'd like to build an electronic power supply. I have the elementary electrical experience, plus i know an electrical engineer who has experience with high voltage lights (though he knows nothing about film projectors) Any suggestions would be appreciated.

Hi Maurice, I couldn't get the link to open - where did you find this?

I couldn't find it myself.
But, try this one. It all sounds a bit technical, but there may be something of interest.

I managed to find a ballast and ignitor from a spotlight that uses the same bulb. New old stock too.

Well done, Robert,
I assume that the two parts shown are, in fact, all as one.

[Kevin Faulkner]

That's one big ballast. I'm keen to see how you get on with this Robert. Keep us posted with some pics.

[Robert Saraceno]

Thanks Maurice, i got lucky.I'll definitely post some pics Kevin. I was amazed I was able to track down a ballast.

[Kevin Faulkner]

Good luck with it all.
