Samsung SP-A600 Projector Brightness
I do love bright projectors. When it comes to the SP-A600's brightness in its "best" mode, it is one of the brighter ones out there. Most 1080p projectors measure between 300 and 600 lumens in best mode. Only rare (and expensive) models exceed 1000 lumens in best mode.
These were the measurements for all modes, pre-calibration. Shown along with the lumens are the color temperture measurements for white (100 IRE):
Vivid= 1017 @ 9583K
Dynamic= 638 @ 8399K
Standard= 702 @ 7235K
Movie 1= 738 @ 6155K
Movie 2= 669 @ 5034K
User 1= 729 @ 6145K
User 1 seems to be virtually identical to Movie 1, with the small measured differences within the margin of error of our equipment.
Post calibration, Movie 1 (User 1) 715 lumens measured @6467K.
Switching to low lamp, brightness drops to 522 lumens, a larger than typical drop of 27% (20-25% is most typical). That percentage drop should hold in all modes.
With a measured 1017 lumens in Vivid mode, that puts the Samsung SP-A600 projector in the high side of average range for a bright mode for projectors in this price range. (Note, a few, however can get much brighter, such as the Epson Home Cinema 6100, which is about 50% brighter in best mode, even though the Epson is over 200 lumens less bright when comparing best modes.)
Going from mid-point on the zoom to full telephoto (it's really not far to go) drops the brightness by about 12.5%. Going from mid-point to full wide angle increases brightness by 4.5%

To give you an idea of how the various "bright modes" compare, below are the same image shot with the same exposure. The first is Vivid, followed by Dynamic, then Standard:
