Cinetron HD700 Brightness
The HD700 projector has 6 preset modes - of those, the 3 User modes start out exactly the same, and very similar to Theater mode. Shown below is measured brightness of each mode, and the color temperature measured for white (100 IRE).
Best Mode: After calibration, there was no real difference in brightness of Theater mode. Mike recorded 864 lumens, a drop of only 4 lumens and well within the accuracy of the equipment.
Brightest Mode: 961 lumens. Dynamic mode is defiinitely cooler looking than the calibrated Theater mode, but provides an extra 100 lumens, when needed
The Effect of zoom lens positioning on brightness: Our standard measurements reported are done with the zoom at its mid-point. Here are relative numbers from the Cinema 1 mode, for different lens positioning From a percentage standpoint, the differences will be the same for any mode, as you change the lens angle:
Zoom out: 852 (closest to the screen - wide)
Mid-zoom: 868 (mid-point on the zoom)
Zoom in: 702 (furthest from the screen - tele)
Those are the strangest readings I've seen in terms of the zoom affect on brightness. Normally Zoom out is the brightest, and as you move towards the more telephone zoom in, the lumen output drops. Mike doublechecked these measurments, and yes, Zoom out is actually dimmer than the midpoint.
I've been wracking my brain about how that could be. My guess may relate to the iris, which may not open fully wide enough to pass all light when the lens is at wide angle? Doesn't really matter why though, except that maximum lumens is one rational for ceiling mounting close, instead of shelf mounting further back.
The Effect of Low lamp (eco) mode on brightness:
Low lamp power ("Normal" lamp mode), Theater: 868 lumens
High lamp power ("Economic" lamp mode), Theater: 679 lumen
That works out to a drop of 22% of brightness when running the lamp in ow lamp mode. That same percentage difference should be unchanged, regardless of preset mode. Most projectors' low power modes drop power between 20 and 25%.
