Genuine USHIO – 100% Original, Never Re-Lamped
This is a brand-new, original USHIO DXL xenon lamp—not a used original bulb that has been re-lamped with a new burner or fitted with a replacement reflector. Every lamp we sell is manufactured by USHIO in Japan as a complete, sealed unit. No recycled parts, no refurbished housings, no re-lamped cores. Using a genuine OEM lamp ensures reliable ignition, stable arc performance, consistent brightness throughout its rated life, and full compliance with Barco’s and Christie’s thermal management specifications. Non-genuine, re-lamped, or third-party compatible xenon bulbs often suffer from arc instability, flickering, color shifts, and premature failure—and may void your projector’s warranty or damage the lamp house.
