Twin Pack Replacement Lamp

The Panasonic ET-LAD120W twin pack supplies two 420 Watt projector lamps in one box. Each unit is built with original OEM bulbs and high-temperature housings for extended service life. The pack is designed for venues that run projectors daily and want a spare on hand.

Upgrade From Third Party Lamps

Original bulbs last three times longer than replacement bulbs while delivering better brightness and more pronounced colour contrast. The jump is worth it when downtime is costly and image quality must stay consistent across multiple presentations.

Fits PT DW830 DX100 DZ870 Series

These lamps install directly into the listed Panasonic PT-DW830, PT-DX100 and PT-DZ870 models without adapters. The twin pack frees up storage space by combining two replacements in a single shipment and keeps a backup ready for the next scheduled change.
