Thank you very much. If you pull out the ballast and transformer and replace it, you will not loose too much weight,because the electronic ballast is pretty heavy as well and the cost are very high for such old lamps. For those who still use it every day, an electronic ballast will reduce lamp costs.
If someone thinks of replacing it, there is the "turbo conversion kit" available. (edit: that kit doesn't contain a new ballast) I think, it contains an electronic ballast,too. ( edit: No, it doesn't!) That produces much more light output as well.
Nope - the turbo kit is a lamp socket, igniter, lenses, and stickers plus some odd hardware. Same ballast, same reflector . . . (I just got about the last kits from HES last year and did four of mine).
The new Cyber is e-ballast, but that has nothing to do with the Turbo mod to the original, which was to go from MSR1200 to MSR1200-SA . . . the new one is a 2000 watt lamp . . .
Sorry, was jetlagged as heck yesterday. The turbo conversion from SV also includes belly and optic fan trays and cooling bafffles. It's not a hard change overall, but does take a bit of time.
The addition output on the turbo is mainly from the additional optical efficiency of the short arc lamp. The lenses are just for sharper gobo projection, and the fans since more transferred light means more heat. Not at quiet as the SV anymore either, if that matters to you.
My next version of the cyberlights restauration would be an additional fan for the lithos, but there is not much space at all. If you use two wheels at the same time, there is no air movement between.
I replaced the "litho housing" fan already against a much better one. The standard fans are not that good quality. This produces a lot less sound level, too.
The "light house" fans should be protected by a sheet of glasfibre against the heat of the lamp. The bearing and motor of the fans are placed directly on the lamp heated aluminium. In my opinion, this is a failure in design that cause the fans to fail very soon.
Not sure what is going on in your fixtures, but on mine, the belly fans have no direct exposure to the lamp as stock - there is a full sheet metal baffle between the two. And the optic fan tray in the front moves a good bit of air. You might also note that the passages in the Cyber body tend to draw air from the front optic area, through the main optic cavity, into the lamphouse and then exhaust via the ridge fan, at least in the SV and Turbo, and frankly, I have never noted any tendency for the optics to overheat in mine, even when run in 8 to 10 hour stints.
And the blowers in mine seem to be quite good quality, and quite quiet . . . I have to wonder if someone "upgraded" yours in a prior life?
There are the original fans inside with the yellow sticker. The metal where the fans are mounted on is directly heated from reflector and lamp. In this case, the bearing from the fan is directly heated from the metal, because there is no airflow at all. You can prevent it, if you just put some sheet of fibreglas in between. It will cost barely nothing and is easy to install. So there is no argument not to do it.
I just wanted to protect the gobos from the heat with extra fans. I is not nessesary. Just because I can do it. I got 55€ fans for 9€ each with much better quality than the original ones. They don't mechanically fit into the lamp housing, but they work perfect in the upper housing. The small extra gobo fans are available for 1,50€ each.
