i thought it was 15-20% for JVC's in the past?
Most folks who have measured the lumens in the RS50 thread has stated their general throw - there is a growing pattern here which doesn't add up.
How is it that the RS50/60's are dropping a substantial amount of lumens once any of the color profiles are enabled? Even professional reviewers are finding this and thinking something is wrong with the model they were sent to review. I am curious if JVC is going to cherry pick an RS60 to send to Art since his first model couldn't muster more than 500 lumens in any of the color profiles.http://www.projectorreviews.com/blog...ck-first-look/
@ Ron - thank you for posting the spreadsheet for the 9 point measurement. I will do this before I swap out the lamp and once again after the new lamp is installed.
Mid range throw, 150 hours on the lamp, center measurement only.
8500K / Color profile = OFF (max brightness): 786 lumens
THX mode - 455 lumens
D65 Calibrated (red is low, pulling back green / blue gain for 100% RGB) - 354 lumens
My Mitsubishi HC5500 3LCD from 3 years ago is brighter than this with lower advertised lumens.
