Same Specifications, Why Choose Zorsika PRO?

For high-demand standard lamp modules like the NP34LP, the Zorsika PRO series provides OEM-equivalent replacement solutions with matching power, arc gap, and reflector size, tested unit by unit before shipping, ready for installation without any structural modifications.

• Specs matched: Power, arc gap, and reflector size match OEM specifications item by item
• Unit-by-unit testing: Each lamp is light-tested before shipping for guaranteed brightness and stability
• Warranty commitment: 180-day warranty on lamps; normal use with non-human damage is covered by after-sales service
• Stable supply: Supports bulk procurement and project-based orders

In short: If you want OEM-quality performance with more peace of mind, the Zorsika PRO series projector lamps are designed exactly for this scenario.

Note: Brightness, lifespan, and other performance metrics vary significantly depending on machine condition, usage environment, and thermal management. Zorsika does not provide unified numerical guarantees. We recommend ordering 1-2 sample units for light testing before bulk procurement.

Frequently Asked Questions

Q: Why choose Zorsika PRO over OEM?

A: The core philosophy of Zorsika PRO series lamps is "OEM specs, self quality control": wattage, arc gap, and reflector size are matched item-by-item to OEM specifications, with an additional lamp-by-lamp illumination test before shipment, backed by 180-day warranty. Compared to OEM, it's more worry-free overall; compared to other alternatives, it offers more stable quality control.

Q: How to choose between factory box, bare lamp, and compatible?

A: If you prioritize stable brightness and long-term reliability, Zorsika PRO series lamps are the top choice—matched item-by-item to OEM specs, with lamp-by-lamp illumination testing before shipment, performance on par with OEM, more worry-free overall, and 180-day warranty; for regular business/education and meeting room use, PRO series is also more worry-free overall. Other alternative lamps may cost less, but lamp core sources and quality control vary significantly, with higher risks of brightness degradation and shortened lifespan—they are only recommended for temporary backup units.

Q: What to do if the machine shows lamp not recognized after replacement?

A: First confirm whether you performed lamp hour reset—most prompts are caused by uncleared timer. If it still errors after reset, contact Zorsika technical support; we provide reset methods and troubleshooting guidance for corresponding models.

Q: My machine is not on the 3-model list above. Can I use NP34LP?

A: The list shows verified models, not all compatible models. NEC products from the same generation often share lamp modules. Take a photo of the machine nameplate and original lamp label and send it to Zorsika technical support to confirm compatibility.

Q: Is there an installation guide for NP34LP?

A: Yes. The lamp door position and disassembly/reassembly steps are essentially the same for these NEC 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 180-day warranty; normal use and non-human damage (such as lamp explosion, abnormal early brightness degradation) are covered by after-sales service; brightness衰减 within standard range is normal wear and not covered by warranty.

Before Ordering, Check These Three Things

1. Verify nameplate model: Open the projector lamp door; the model on the lamp module label should exactly match NP34LP. Some NEC models may have suffix differences like -V or +, but lamp modules are usually interchangeable—when in doubt, send a photo of the nameplate to Zorsika technical support for confirmation.
2. Confirm lamp configuration: The same model comes in four configurations: factory box, bare lamp, compatible alternative, and second-hand. These differ significantly. Bare lamp uses OEM lamp core with third-party housing, offering the best overall value; be sure to clearly state which configuration you need on the order to avoid disputes upon delivery.
3. Verify physical specifications: Reflector size 51X51D, socket E20.9, and arc gap must match the original lamp—any mismatch may result in installation failure or failure to ignite.

After Lamp Replacement, Keep These Points in Mind

• Clean dust promptly: Dust buildup on the air intake and filter directly raises lamp operating temperature—clean once every 1-2 months in dusty environments, or every 3-6 months in normal office environments.
• Use eco mode wisely: This lamp supports 260W/220W dual wattage; switching to eco mode in typical presentation scenarios significantly reduces lamp thermal load.
• Avoid frequent on/off cycles: Thermal cycling is a major cause of lamp wear—if not using for a short period, use the blanking function rather than repeatedly powering off.
• Proper shutdown: Wait for the fan to stop before cutting power—hot shutdown causes sudden lamp cooling, a common cause of lamp explosion.
• Reset after replacement: Be sure to perform lamp hour reset in the menu after installing the new lamp; otherwise the machine will keep alarming based on the old timer.
