Where It Works: List of 6 Compatible Models (With Specifications)

Below are the verified compatible models for the WD439 (Komei projectors), each with brightness, resolution, and zoom ratio:

Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (refer to the model nameplate or user manual for final confirmation); lens compatibility is determined by the projector's mount interface and optical structure. For models not listed, please contact Zorsika technical support for verification.

Why Choose Zorsika

For professional lenses like the WD439, Zorsika benchmarks every parameter against the original factory optical specifications (focal length, throw ratio, lens groups). The lens coating process is identical, delivering sharp images with no soft edges—ready to install and use right out of the box.

Zorsika's equivalent replacement lens is compatible with 6 Komei models, including the EFL-WU72, EFL-WU66, EFL-WU86, EFL-4K76, and QLP-G950U; enter WD439 in the search system on the Zorsika official website to view the full list of compatible models.

• Optical Benchmarking: Focal length, throw ratio, and lens groups matched to original factory parameters
• Resolution Testing: Each lens individually tested before shipment; MTF data available on request
• Coating Process: Lens coating on par with the original factory, reducing light loss
• Stable Supply: Supports bulk procurement and project-based supply

In short: the lens is the optical core—don't gamble image quality against a price difference. Zorsika projector lenses are manufactured to original factory drawings, offering a stronger overall value proposition.

Note: Actual image performance may vary depending on projector condition and installation environment; we recommend testing one unit before bulk procurement.

FAQ

Q: Why choose Zorsika instead of the original factory?

A: Zorsika lenses are manufactured to the original factory optical drawings, with lens groups, coatings, and throw ratios benchmarked item by item, and each lens undergoes resolution testing before shipment. Compared to the original factory, we offer shorter lead times and better overall value; compared to other replacement lenses, our optical quality is backed by data.

Q: Can this lens replace the original factory one?

A: The lens is the core of the projector's optical path and directly determines sharpness and color. Zorsika lenses (models listed in the specification table above) are benchmarked against original factory optical parameters (focal length, throw ratio, lens groups) item by item, with an identical lens coating process, delivering sharp images with no soft edges. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, making brightness loss and color shift immediately visible. For professional and exhibition applications, Zorsika is the recommended choice.

Q: My projector isn't in the list of 6 models above—can I use the WD439?

A: The list covers verified models but isn't exhaustive. Professional projectors from the same brand and generation often share the same lens mount. For a more reliable answer, send a photo of the model nameplate and the original lens to Zorsika technical support for confirmation.

Q: Does the WD439 come with installation instructions?

A: Yes. The lens removal and installation steps for Komei projectors of this type are largely the same; contact Zorsika sales to get illustrated or video instructions for your specific model.

Q: What is the warranty period for the lens?

A: All Zorsika projector lenses come with a 12-month warranty. For normal use and non-man-made damage (e.g., impact, water ingress, or unauthorized disassembly), please contact our after-sales service directly. The warranty period is calculated from the shipping date on the delivery note.

Lens Maintenance Tips

• Power off before changing lenses: Always shut down the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the mount with power on.
• Don't touch the glass: Fingerprints and oil stains directly affect image quality. Hold the lens by the barrel, not the glass; use an air blower for dust and never wipe with a dry cloth.
• Focus before tightening: After installation, test focus first, then tighten the locking screws to prevent image drift from loosening over time.
• Keep the mount clean: Dust on the bayonet and contacts can cause poor connectivity; clean them when swapping lenses for extra safety.
