GE 1kw CID PAR64 discharge 2 Decided to fire up the GE CID PAR64 lamp that I got a while ago. With the exposure reduced even further, the main arcstream can be seen. I used a Philips 1000w SON ballast together with a 400w Parmar SON ballast in parallel. Ignitor was the high voltage pulse transformer located inside the Thorn OQ1000 fitting that I used with a simple push-to-make switch wired in to trigger it. Apologies for the soft image as I was using 3 stacked ND8 filters and also shooting at an angle through the very thick outer envelope doesn't help either.

Decided to fire up the GE CID PAR64 lamp that I got a while ago.

With the exposure reduced even further, the main arcstream can be seen.

Apparently due to the tiny arc gap on these, the halide dose runs completely evaporated when the CSI lamp is fully run up Cool

Max said in LG that the reason why this lamp is unsaturated, is because of the volatility of the halides, which are tin and indium.
These halides have high pressure. and indium evaporate first, which cause this lamp to be blue for several secs during run-up. I've seen this blue phase in my 8000K 70W Aliexpress MH lamp: It is blue than turning into a cyan white light, as the thallium ionized before the indium.
