I was planning a calibration and some lux readings over the weekend but the lamp counter issue has me reconsidering this model.
I'm fairly confident BenQ would likely claim ignorance or that it's a bug but this is obviously concerning for multiple reasons.
I've noticed the rapid pace of the "lamp hours," as well, but it's not a deal killer for me. Sure, I'd like it to be as accurate as possible, but the benefits far outweigh the negatives.
I can always keep a spare lamp around and when it goes - - it goes! Chances are I'll notice the lamp "dimming" long before then. (Hopefully.....

Getting to know the lamp hour
When the projector is in operation, the duration (in hours) of lamp usage is automatically calculated by the built-in timer.
See "Setting Lamp Power as Economic or SmartEco" below for more information on Economic mode.
To obtain the lamp hour information:
1. Press MENU/EXIT and then press / until the System Setup : Advanced menu is highlighted.
2. Press to highlight Lamp Settings and press MODE/ENTER. The Lamp Settings page displays.
3. The lamp hour information is shown in the row of Equivalent Lamp Hour.
4. To leave the menu, press MENU/EXIT.
Extending lamp life
The projection lamp is a consumable item. To keep the lamp life as long as possible, you can do the following settings via the OSD menu.
• Setting Lamp Power as Economic or SmartEco
Using Economic mode reduces system noise and power consumption by 30%. Using SmartEco mode reduces system noise and lamp power consumption by up to 70%. If the Economic or SmartEco mode is selected, the light output will be reduced and result in darker projected pictures
Setting the projector in Economic or SmartEco mode also extends the lamp life. To set Economic or SmartEco mode, go to the System Setup : Advanced > Lamp Settings > Lamp Power menu, and press MODE/ENTER. The Lamp Power page displays. Then press / repeatedly until your
desired mode is selected and press MODE/ENTER
