Hi,
I'm looking at picking up a Seleco SVT150 CRT with low
hours on the tubes. It's a 110 ANSI lumen unit and I'm
wondering how big a screen size I could expect (with suitable
brightness) when projecting on to a white wall and/or
screen. The room will be almost completely dark when the
unit will be in use. I've seen several formulas for screen
brightness, however I've also seen an 8" CRT project a
quite bright, much bigger picture than the formulas would
suggest. Just a bit confused.
Mike.
