Compatible Projector Models: 2 Infocus Projectors

The following are verified compatible projector models for SP-LAMP-077 in the Infocus projector lineup, with model numbers separated by commas:

IN3924, IN3926

Note: Projectors from the same generation often share the same lamp module. For models not listed, please contact Zorsika technical support for confirmation.

Verify These Three Things Before Ordering

1. Verify the model nameplate: Open the projector lamp door and check that the model on the lamp module label matches SP-LAMP-077 exactly. Some Infocus models may have suffixes like -V or + which are typically interchangeable at the lamp module level. When in doubt, take a photo of the nameplate and send it to Zorsika technical support for confirmation.
2. Confirm lamp condition/type: The same model is available in four conditions: original packaged, original bare, compatible, and refurbished. These four types vary significantly. Original bare refers to original manufacturer arc tube with third-party lamp housing, which usually offers the best value. Be sure to specify which condition you need on your order to avoid disputes upon delivery.
3. Verify physical specifications: Reflector size 51X51D, socket E20.9, and arc gap must match your original lamp. Any mismatch may result in the lamp not fitting or failing to ignite.

What the Zorsika PRO Series Gives You

For high-usage standard lamp modules like SP-LAMP-077, the Zorsika PRO Series offers OEM-spec replacement solutions with power, arc gap, and reflector size matched item by item to the original factory specs. Every unit undergoes individual lamp-on testing before shipment—ready to install without any structural modifications.

• Spec Match: Power, arc gap, and reflector size matched item by item to OEM parameters
• 100% Tested: Each unit undergoes individual lamp-on testing before shipment for guaranteed brightness and stability
• Warranty Commitment: 180-day warranty on lamps; after-sales service for正常使用 non-human damage
• Stable Supply: Supports bulk purchasing and project-based orders

Bottom line: If you want OEM-quality performance but prefer a more hassle-free experience overall, the Zorsika PRO Series projector lamp is built exactly for this.

Note: Brightness and lifespan vary significantly depending on machine condition, usage environment, and thermal management. Zorsika does not make uniform numerical commitments. We recommend ordering 1-2 sample units for lamp-on testing before bulk purchasing.

Regular Maintenance: Help Your Lamp Last Longer

• Clean Dust Promptly: Dust buildup on the air intake and air filter directly raises the lamp's operating temperature. In dusty environments, clean every 1-2 months; in standard office settings, every 3-6 months.
• Use Eco Mode: This lamp supports 225W / 160W dual power modes. Switching to eco mode in everyday presentation scenarios significantly reduces thermal load on the lamp.
• Avoid Frequent Switching: Thermal cycling is a major cause of lamp wear. If you don't need to use the projector for a short period, use the blank function instead—don't repeatedly power on and off.
• Proper Shutdown: Always wait for the fan to stop before cutting power after shutdown. Thermal shock from cutting power while hot is a common cause of lamp failure.
• Reset After Replacement: Be sure to reset the lamp timer in the menu after installing a new lamp; otherwise the machine will continue alarming based on the old timer.

Frequently Asked Questions

Q: My machine isn't on the list above. Can I still use SP-LAMP-077?

A: The list represents verified models only—it doesn't mean those are the only options. Infocus products from the same generation often share lamp modules. Take a photo of the unit's nameplate and the original lamp label and send it to Zorsika technical support; we can help confirm compatibility.

Q: How do I choose between OEM-packaged, OEM-bare, or compatible lamps?

A: If you prioritize brightness stability and long-term reliability, the Zorsika PRO Series lamp is the top choice—matched item by item to OEM specs, 100% individually tested before shipment, OEM-level performance with a more hassle-free experience, backed by a 180-day warranty. For regular business, education, and meeting room use, the PRO Series is also the smarter, more worry-free option. Other compatible lamps are cheaper but vary widely in lamp core sourcing and quality control, with higher risks of brightness decay and shorter lifespan—best reserved for temporary backups only.

Q: Why choose Zorsika PRO over OEM?

A: The core logic behind the Zorsika PRO Series lamp is "OEM specs, self-controlled quality": power, arc gap, and reflector size matched item by item to OEM originals, plus an additional 100% individual lamp-on test before shipment and a 180-day warranty. Compared to OEM, it's more hassle-free overall. Compared to other compatible options, it delivers more stable quality control.

Q: After replacing the lamp, the machine shows "lamp not recognized"—what should I do?

A: First confirm whether you reset the lamp timer. The vast majority of such alerts are caused by an uncleared timer. If it still errors after resetting, contact Zorsika technical support—we provide reset procedures and troubleshooting guides for the corresponding models.

Q: Is there an installation guide for SP-LAMP-077?

A: Yes. The lamp door position and removal/replacement steps are essentially identical across these Infocus models. Contact Zorsika sales to get illustrated or video tutorials for your specific model.

Q: How long is the lamp warranty period?

A: Zorsika PRO Series projector lamps come with a 180-day warranty. Normal use and non-human damage (such as lamp burst or abnormal early lumen decay) qualify for after-sales service. Brightness decline within standard ranges is considered normal usage wear and is not covered by warranty.
