Hello Xelablan,

Is there any news about the conversion of the Marin to Xenon?
Do you have pictures? If so could you post them please?     

How does the conversion to HMI of your chinese projector go?  Huh

Hi!

I hear for some HMI conversion on 35mm machines, but there is thing that might be bad, or not, you will tell. Xenon lamp, and carbon arcs before are not used just like that, they have equal RGB spectrum, so 1/3 is red, 1/3 is green, 1/3 is blue, specialy the xenon lamp, and light spectrum is closest to sun.

But HMI has blurry picture and lack of contrast as I heard because mainly is raditing on white spectrum, but how bad is that I can't tell since I newer saw one in action, so I'm wonder did you noticed that and how big is?

I did give a try with halogen also, but that is useful only at home when testing something, but even in smallest portable machine I worked there was 500W xenon lamp which is good up to 5-6m wide screen (scope) with good optics. Since using electronic SMPS rectifier is quite light weight 4kg or so.....
