Lamp information
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. The method of calculating the equivalent 
lamp hour is as follows:
Total (equivalent) lamp hour= 20/9 * (hours used in Normal mode) + 5/3 * (hours 
used in Eco mode) + 20/13 * (hours used in SmartEco)+1 * (hours used in LampSave)
See Setting Lamp mode eco function as Economic or SmartEco mode 
below for more information on Economic mode.
The lamp hour in Economic, SmartEco and LampSave is calculated shorter of that in 
Normal mode. That is, using the projector in Economic, SmartEco or LampSave mode 
helps to extend the lamp hour. 
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. You will see the Equivalent lamp information displaying on the menu.
4. To leave the menu, press Menu/Exit.
You can also get the lamp hour information on the INFORMATION menu.
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 or remote control.
Setting Lamp mode eco function as Economic or SmartEco mode
Using Economic /SmartEco mode will reduces system noise and power 
consumption. If the 
Economic/SmartEco mode is selected, the light output will be reduced 
and result in darker projected pictures, the projector protected for longer working life.
Setting the projector in Economic/SmartEco mode also extends the lamp 
operation life. To set 
Economic/SmartEco mode, go into the SYSTEM SETUP: 
Advanced > Lamp Settings > Lamp mode menu and press 
/. .
The lamp modes are defined as the chart below.

menu and press  / . The time period can be set from 5 to 30 minutes in 5-minute 
increments. If the preset time lengths are not suitable for your presentation, select

							Maintenance 63
Timing of replacing the lamp
When the Lamp indicator lights up red or a message appears suggesting it is time 
to replace the lamp, please install a new lamp or consult your dealer. An old lamp may 
cause a malfunction in the projector and in some instances the lamp may explode.
Do not attempt to replace the lamp yourself. Contact the qualified service 
personnel for replacement.
The Lamp indicator light and Temperature warning light will light up if the 
lamp becomes too hot. See Indicators on page 67 for details.
The following lamp warning displays will remind you to change the lamp.
The warning messages below are for reference only. Please follow the 
actual on-screen instructions to prepare and replace the lamp.
XXXX shown in the above messages are numbers that vary depending 
on different models.
StatusMessage
Install a new lamp for optimal performance. If 
the projector is normally run with Economic 
selected (Setting Lamp mode eco function as 
Economic or SmartEco mode on page 61), 
you may continue to operate the projector 
until the next lamp warning appears.
A new lamp should be fitted to avoid the 
inconvenience when the projector runs out of 
lamp time.
It is strongly recommended that you replace 
the lamp at this stage. The lamp is a 
consumable item. The lamp brightness 
diminishes with use. This is normal lamp 
behavior. You can replace the lamp whenever 
you notice that the brightness level has 
significantly diminished.
The lamp MUST be replaced before the 
projector will operate normally.

Replacing the lamp (FOR SERVICE PERSONNEL 
ONLY)
•Hg - Lamp contains mercury. Manage in accordance with local 
disposal laws. See www.lamprecycle.org.
• If lamp replacement is performed while the projector is suspended 
upside-down from the ceiling, make sure that no one is underneath the 
lamp socket to avoid any possible injury or damage to the human eyes 
caused by fractured lamp.
• To reduce the risk of electrical shock, always turn the projector off and 
disconnect the power cord before changing the lamp.   
• To reduce the risk of severe burns, allow the projector to cool for at 
least 45 minutes before replacing the lamp.
• To reduce the risk of injuries to fingers and damage to internal 
components, use caution when removing lamp glass that has shattered 
into sharp pieces.
• To reduce the risk of injuries to fingers and/or compromising image 
quality by touching the lens, do not touch the empty lamp 
compartment when the lamp is removed.
• This lamp contains mercury. Consult your local hazardous waste 
regulations to dispose of this lamp in a proper manner.
• To assure optimal performance from the projector, it is recommended 
that you purchase a BenQ projector lamp for lamp replacement.
• Ensure good ventilation when handling broken lamps. We recommend 
that you use respirators, safety glasses, goggles or face shield and wear 
protective clothing such as gloves.
