Metal Halide is in the 4500K to 6000K range which is better suited for projection purposes. ••• More options Share pinkmouse Ex-Moderator Joined 2002 2005-06-25 11:25 am #3 2005-06-25 11:25 am #3 HPS is also very peaky, and that gives very poor colour rendition. ••• More options Share O Optical Member Joined 2002 2005-06-26 3:17 am #4 2005-06-26 3:17 am #4 yes, but is there any photo evidence? maybe the panel colouring can be tuned around it? probably not i know.. you cant make what isnt there, but id still like to see some photo evidence... ••• More options Share M Mikey p Member Joined 2004 2005-06-26 4:28 am #5 2005-06-26 4:28 am #5 Someone did post a picture of a HPS projection shot on one of the other forums, but I can't remember which one.
