Christie 003-120730-01 Projector Lamp for LW41 LX41 | OEM Replacement

003-120730-01 is a lamp module still widely used on Christie projectors, covering 2 models. This guide consolidates the lamp module specifications, replacement compatibility assessment, model compatibility list, and pre-replacement checks in one place.

1. Lamp Module Specifications

The above specifications are taken from the Zorsika product database. Contact our sales team for the complete technical datasheet.

2. Replacement Compatibility: Check These Three Physical Parameters First

The key specification on record for this lamp is power: 245W. Whether it can be used as a substitute depends on whether these three or four specifications match those of the original lamp item by item—wattage determines whether the lamp driver can power it, reflector size determines whether it fits in the lamp chamber, and socket/base and arc gap determine whether it can ignite.

Matching wattage does not mean universal compatibility. Many models on the market have the same wattage but differ in reflector size by a few millimeters. Forcing the lamp to fit can prevent the lamp chamber cover from closing, shift the optical axis, or block the cooling airflow. Conversely, even if the reflector is the same but the wattage differs, the lamp driver may report an error or the lamp may not ignite at all. The correct assessment order is to match the OEM lamp module model first, verify wattage and reflector size next, and check the socket form factor last.

This lamp is used in models equipped with LCD panels. Different panel technologies have different optical-path requirements for the lamp arc position. Even if a replacement built for a different panel technology physically fits, it may produce an uneven brightness distribution, so such substitution is not recommended.

3. Compatible Projector Models (2 Models, Christie)

The following Christie projector models have been verified as compatible with 003-120730-01:

LW41, LX41

This list contains verified models and is not exhaustive. Projectors from the same generation often share the same lamp module. For models not listed, send us photos of the projector nameplate and the original lamp label for confirmation.

4. Three Checks Before Replacement

1. Verify the nameplate model: Open the lamp door and confirm that the model on the lamp module label exactly matches 003-120730-01. Some Christie models have suffixes such as -V and +, and lamp modules are generally interchangeable. If you are unsure, send us photos of the nameplate for more reliable confirmation.
2. Confirm the lamp configuration: The same model comes in four variants: an OEM lamp in its original packaging, a bare OEM lamp, an aftermarket replacement, and a used lamp, with significant differences among them. A bare OEM lamp combines an OEM arc tube with a third-party lamp holder and generally offers the best overall value for money. Be sure to specify which version you need when placing your order to avoid disputes after delivery.
3. Verify the physical specifications: These specifications must match those of the original lamp. If any one differs, the lamp may not fit or may not ignite.

5. Choosing Between Zorsika PRO and Common Alternatives

Zorsika PRO Series projector lamps are built to “OEM specifications and in-house quality control”: key parameters are benchmarked item by item against the OEM specifications, each lamp is individually tested to confirm that it lights up before shipment, and the lamps are ready to install without structural modifications.

OEM parts offer exact consistency, but at a higher overall cost; aftermarket alternatives are cheaper, but their arc tube sources and quality control are less reliable. Common problems include low brightness, a green color-temperature cast, and noticeable lumen depreciation after a period of use. Zorsika takes a middle-ground approach: OEM-benchmarked specifications, in-house quality control, and a more hassle-free overall experience.

Brightness and service life vary substantially depending on projector condition, operating environment, and cooling conditions. Zorsika does not make uniform numerical performance guarantees; before a bulk purchase, test one or two lamps to confirm that they light up.

6. Frequently Asked Questions

Q: My projector is not among the 2 models listed. Can I use 003-120730-01?

A: The list contains verified models and is not exhaustive. Christie products from the same generation often share the same lamp module. Send photos of the projector nameplate and the original lamp label to the Zorsika technical team, which can confirm whether the lamp is compatible.

Q: How should I choose between an OEM lamp in original packaging, a bare OEM lamp, and an aftermarket replacement?

A: If stable brightness and long-term reliability are your priorities, a Zorsika PRO Series lamp is the best choice. It is matched item by item to the OEM specifications, individually tested to confirm that it lights up before shipment, benchmarks OEM performance, offers a more hassle-free overall experience, and includes an 180-day warranty. For routine business and educational use and in meeting rooms, the PRO Series is also the more hassle-free option. Other replacement lamps cost less, but their arc tube sources and quality control vary considerably, increasing the risk of brightness degradation and shortened service life. They are recommended only for temporary backup projectors.

Q: Why choose Zorsika PRO instead of an OEM lamp?

A: The core principle of the Zorsika PRO Series is “OEM specifications and in-house quality control”: power, arc gap, and reflector size are matched item by item against the OEM specifications, while an additional individual lighting test is performed before shipment, backed by an 180-day warranty. Compared with OEM lamps, it provides a more hassle-free overall experience; compared with other alternatives, it offers more consistent quality control.

Q: What should I do if the projector reports that the lamp is not recognized after replacement?

A: First, confirm that the lamp-hour counter has been reset. Most such messages are caused by an uncleared timer. If the error persists after the reset, contact the Zorsika technical team. We provide reset instructions and troubleshooting guidance for the corresponding projector model.

Q: How long is the lamp warranty?

A: Zorsika PRO Series projector lamps come with an 180-day warranty. Under normal use, damage not caused by the user—such as a ruptured lamp or premature abnormal lumen depreciation—is eligible for after-sales service. Brightness degradation within the standard range is considered normal wear and is not covered by the warranty.
