Zorsika's equivalent model for BE421 (<15K Lumens) is compatible with 12 projector models including Christie and Optoma DWU1800-JS, DWU2400-JS, 4K1600-JS, 4K2100-JS, ZK1320 and more. Enter BE421 (<15K Lumens) in the search system on Zorsika's official website to find the complete compatibility list.

• Optical Alignment: Focal length, throw ratio, and lens elements matched to OEM specifications
• Resolution Testing: Each unit tested before shipment, MTF data available for review
• Coating Process: Lens coatings at the same level as original manufacturer, minimizing light loss
• Stable Supply: Supports bulk procurement and project-based delivery

In short: The lens is the optical core—don't gamble with picture quality over price differences. Zorsika projector lenses are manufactured according to original factory drawings, offering overall better value.

Note: Actual imaging performance depends on projector condition and installation environment. For bulk orders, we recommend testing one unit first before committing.

What to Watch When Replacing a Lens?

• Power off first: Always shut down and wait for the cooling fan to stop before removing or installing a lens to avoid damaging connectors with live electricity.
• Don't touch the glass: Fingerprints and oils directly affect image quality. Hold the lens by the barrel, not the glass. Use an air blower for dust—never wipe with cloth.
• Lock after focusing: Test focus after proper installation, then tighten the mounting screws. Loose screws over time can cause image drift.
• Keep connectors clean: Dust on mounts and contacts causes poor connectivity. Clean them when replacing the lens for better reliability.

FAQ

Q: My model isn't on the list of 12. Can I still use BE421 (<15K Lumens)?

A: The list shows verified models, not an exhaustive inventory. Projectors of the same brand and generation often share lens interfaces. Take photos of the unit nameplate and original lens and send them to Zorsika tech support for confirmation.

Q: Can this lens replace the OEM?

A: The lens is the core of the projection light path, directly determining sharpness and color accuracy. Zorsika lenses (models in the spec table above) align with OEM optical parameters (focal length, throw ratio, lens elements) item by item, with matching coating processes. They deliver sharp, crisp images with no edge blurring. Generic replacement lenses often use inferior glass with fewer coating layers, resulting in noticeable brightness loss and color shift. For professional and exhibition applications, Zorsika is the better choice.

Q: Why choose Zorsika over the OEM?

A: Zorsika lenses are manufactured according to OEM optical blueprints, with lens elements, coatings, and throw ratios matched item by item, and each unit undergoes resolution testing before shipment. Compared to OEMs: shorter lead times and better overall value. Compared to other third-party lenses: documented optical performance with test data.

Q: The lens doesn't match the screen size. What should I do?

A: First confirm the lens interface type and optical axis position for your projector model, then select a lens with the appropriate throw ratio based on your actual installation distance. If unsure, send your installation distance and screen dimensions to Zorsika technical support—we'll recommend the right lens.

Q: Is there an installation guide for BE421 (<15K Lumens)?

A: Yes. Lens removal and installation steps are essentially the same for models like Christie and Optoma. Contact Zorsika sales to get illustrated or video guides for your specific model.

Q: What's the warranty period for the lens?

A: All Zorsika projector lenses come with a 12-month warranty. Normal use and non-human damage (such as drops, liquid exposure, or unauthorized disassembly) are covered. Contact after-sales service directly. Warranty period is calculated from the shipping document date.
