Re: Formula with best mix of accuracy and gain

Thanks for the reply. I actually zoom to achieve 2.35 but I took these measurements zoomed out. So that 16:9 fits on the screen with leftover space to the left and right. My 16:9 diagonal is actually 95". The calculations I did were correct for that number. Im thinking that instead of painting I may be better served by just buying a new bulb.

That seems a bit odd for a lamp that only has 500 hours on it - it may not be a bad idea to contact the manufacturer and see if there is anything amiss with the lamp and if they would replace it.

Oops, I misspoke. It actually has around 615 on it, but your point still stands. it shouldn't be THAT dim.

Now, when I open the iris, I get about 10fL, which is around 280 lumens. Better, but still pathetically dim.

Re: Formula with best mix of accuracy and gain

Silas, at this point I wouldn't recommend painting your white Sintra screen until you talk with JVC and find out if there is a problem with your bulb or not. At the lumens you are currently dealing with there is no DIY solution that is any higher gain than your screen and color neutral.

Please keep up apprised of your situation.
