Christie 003-120577-01 Projector Lamp for DHD800 | OEM Replacement

003-120577-01 is a lamp module that remains widely deployed on Christie projectors in the field, covering 1 model. This guide presents its specifications, replacement compatibility, model compatibility list, and pre-replacement checks in one place.

1. Lamp Module Specifications

These specifications are sourced from the Zorsika product database. Contact sales for the complete technical datasheet.

2. Can It Be Used as a Substitute? Check These Three Physical Parameters First

The core catalog parameters for this lamp are: power 330W / 264W, reflector size 56X56D, socket E21.7, and arc gap 1.3mm. Whether it is a suitable substitute depends on whether these parameters match those of the original lamp: power determines whether the lamp driver board can drive it, reflector size determines whether it fits into the lamp housing, and the socket and arc gap determine whether it will light.

Identical power does not mean universal compatibility. Many lamp models on the market have the same power rating but differ in reflector size by several millimeters. Forcing installation may prevent the lamp housing cover from closing, shift the optical axis, or block the cooling airflow. Conversely, if the reflector is the same but the power rating differs, the lamp driver board may report an error or fail to light the lamp. The correct assessment order is to verify the original lamp module model first, then check the power rating and reflector size, and finally confirm the socket format.

This lamp is used in projectors with DLP panel technology. Different panel technologies have different requirements for the lamp arc position within the optical path. Even if a substitute fits across panel technologies, uneven brightness distribution may occur, so this type of substitution is not recommended.

Standard Mode and Eco Mode

The dual power ratings are the two lamp drive power levels supported by the lamp module. Whether they can actually be switched depends on the projector menu, as not all models provide access to the eco setting.

3. Compatible Models (1 Model, Christie)

The following compatible projector models have been verified for 003-120577-01 in Christie projectors:

DHD800

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 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 003-120577-01. Some Christie models carry suffixes such as -V and +, and the lamp modules are generally interchangeable. If uncertain, the safest option is to send us a photo of the nameplate for confirmation.
2. Confirm the lamp version: Four versions are available for the same model—factory-packaged, factory bare, aftermarket, and used—and they differ significantly. The factory bare version combines an OEM arc tube with a third-party housing and generally offers the best overall value. Be sure to specify the required version when placing your order to avoid disputes after delivery.
3. Verify the physical specifications: The reflector size 56X56D, socket E21.7, and arc gap 1.3mm must match those of the original lamp. If any of these values differs, the lamp may not fit or may fail to light.

5. Choosing Between Zorsika PRO and Other Alternatives

The Zorsika PRO series projector lamps follow the principle of “OEM specifications with in-house quality control”: key specifications are matched item by item against the OEM, every lamp is tested to confirm that it lights before shipment, and the lamps are ready for installation without any structural modification.

OEM parts offer exact consistency but come at a higher overall cost. Other replacement parts are less expensive, but their arc tube sources and quality control are less consistent. Common issues include low brightness, a greenish color temperature, and noticeable lumen depreciation after a period of use. Zorsika takes a middle path: OEM-matched specifications, in-house quality control, and a more hassle-free overall experience.

Brightness and service life are significantly affected by the projector’s condition, operating environment, and cooling conditions. Zorsika does not make blanket numerical performance claims. Before bulk purchasing, obtain and test one or two samples to confirm that they light properly.

6. Frequently Asked Questions

Q: My projector is not among the 1 model listed above. Can I use 003-120577-01?

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 original lamp label to Zorsika technical support, who can confirm whether the lamp is compatible.

Q: How do I choose between factory-packaged, factory bare, and aftermarket versions?

A: If you prioritize stable brightness and long-term reliability, choose a Zorsika PRO series lamp. Every lamp is matched item by item against the OEM specifications and tested to confirm that it lights before shipment. Its performance is benchmarked against the OEM for a more hassle-free overall experience, and it includes a 180-day warranty. The PRO series is also a more hassle-free choice for routine business, education, and conference-room applications. Other replacement lamps cost less, but their arc tube sources and quality control vary more widely, creating greater risks 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 behind the Zorsika PRO series is “OEM specifications with in-house quality control.” Power, arc gap, and reflector size are matched item by item against the OEM, while every lamp receives an additional lighting test before shipment and is covered by a 180-day warranty. Compared with OEM lamps, the PRO series offers a more hassle-free overall experience; compared with other alternatives, it provides 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, as most such messages result from an uncleared timer. If the error remains, contact Zorsika technical support. 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 include a 180-day warranty. After-sales service is available for normal use without user-caused damage, such as a ruptured lamp or abnormally early lumen depreciation. Brightness degradation within the standard range is considered normal wear and is not covered by the warranty.
