Mitsubishi HC6800 Projector Review

Mitsubishi HC6800 Brightness

The Mitsubishi HC6800 is one of the brighter 1080p home theater projectors out there. Immediately below are the measured lumens of each of the preset modes, (and also the color temperature they produced at 100 IRE) (white)

Mitsubishi HC6800 Projector - Uncalibrated

Lumen Output at various Color Temps at 100 IRE
Medium 687 @ 6583K
High Brightness 946 @ 7864K
Cool 573 @ 9459K
Warm 652 @ 5937K

After doing our calibration of “best” mode, we measured: 578 lumens

Brightest mode – High Brightness, cannot be calibrated, and remains 946 lumens.

The Effect of zoom lens positioning on brightness

Using Warm Temp setting
Zoom out (closest position – wide-angle) 739 lumens
Mid-zoom 687 lumens
Zoom in (furthest from the screen – tele) 608 lumens

The 18% drop from wide angle to telephoto lens settings should be consistent in any mode.

The Effect of low lamp (eco) mode on brightness

Low lamp power, Medium Temp mode 471 lumens
High lamp power, Medium Temp mode 687 lumens

Most home theater projectors lose about 20% – 25% of their brightness going to low power. Perhaps the larger than typical drop partially explains the jump from 2000 hours lamp life at full power to 4000 at low (eco) power, as most others go from 2000 to 3000 when dropping down in power.
