Using the correct lamp

Protect your investment and buy genuine Epson ELPLP15 lamps for your Epson EMP-820P projector. OEM authentic Epson ELPLP15 lamps have been manufactured to meet the specifications of your projector and will keep it working at optimum levels.
Beware of the generics being sold over the Internet! These lamps can damage the sensitive and expensive mechanisms and are also prone to explosions. They have been created with Krypton-85 and other toxic materials that put your health at risk. Installing a knock-off lamp will also void the guarantee on your Epson EMP-820P projector leaving you unprotected should anything happen after installation. Avoid hassles and buy authentic. Look for the seal of approval and buy from an authentic manufacturer. Learn how to protect yourself from counterfeit manufacturers.

Installing a new Epson ELPLP15 lamp

Pre-installation preparations:
1. Turn off the  power to the Epson EMP-820P projector. Wait for a two-minute cool down period — the projector may beep when it’s reached the time limit.
2. Disconnect the power cord after the two minutes is over.
3. Wait an additional 45 minutes to one hour for the Epson EMP-820P projector to cool internally before opening it up.  Wait the full period as these projectors operate under high temperature and you can burn yourself badly.
