When to replace

Depending on the working conditions and setting of the Panasonic PT-D5600UL, projector lamp life may vary. The Panasonic PT-D5600UL uses the Panasonic ET-LAD55 projector lamp power and at 1300 hours the “Replace Lamp” warning is displayed on screen for 30 seconds. That message will be permanently displayed on screen until the Panasonic ET-LAD55 projector is changed. Don’t leave the lamp  as is after the warning message or the projector will automatically shut off and the so the Panasonic PT-D5600UL projector will enter a standby state. It will remain in standby state until the projector lamp is changed.

Choosing projector lamp options

The Panasonic PT-DW5000U comes equipped with two Panasonic ET-LAD55 projector lamps. You have the option of using:

  • SINGLE projector lamp mode: Either of the projector lamp is used – projector automatically chooses the lamp with the shorter operating hours.
  • DUAL projector lamp mode: Both projector lamps are used.
  • Projector LAMP1 : Lamp Unit 1 is always used alone.
  • Projector LAMP2 : Lamp Unit 2 is always used alone.

When only one Panasonic ET-LAD55 projector lamp is used (SINGLE, LAMP1 or LAMP2 options) and it’s been used for 1500 hours consecutively, the Panasonic PT-DW5000U projectors automatically switches to the second lamp. When both Panasonic ET-LAD55 lamps are used simultaneously for 1300 hours straight, the projector will automatically go into standby mode. Create longer projector lamp life by controlling the luminance of the projector lamp:

  • HIGH: Use when you need high brightness is necessary. Both lamps are used with this setting.
  • LOW: Set when high brightness is not necessary. This reduces power and operating noise while using only one lamp.
