Where It Works: List of 2 Compatible Models (with Specs)
Below are the verified compatible models for the WD660 (BenQ projectors), with brightness, resolution, and zoom ratio listed for each:
| Projector Model | Brightness | Resolution | Zoom Ratio |
|---|---|---|---|
| LH730 | 4000 lumens | 1920x1080 | 1.2X |
| LH750 | 5000 lumens | 1920x1080 | 1.62X |
Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (refer to the model nameplate/manual for accuracy); lens compatibility is based on the chassis interface and optical structure. For models not on this list, please contact Zorsika technical support for confirmation.
Same Specs — Why Choose Zorsika
For engineering lenses like the WD660, Zorsika benchmarks each item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes, sharp imaging, and no soft edges — ready to use right out of the box.
Zorsika's same-spec replacement model is compatible with 2 projector models including the BenQ LH730 and LH750; enter WD660 in the Zorsika official website lookup system to see the complete model compatibility list.
- Optical Benchmarking: Focal length, throw ratio, and lens group matched to original parameters
- Resolution Testing: Each unit tested before shipment, with MTF data available
- Coating Process: Lens coatings at the same grade as the original, reducing light loss
- Stable Supply: Supports bulk purchasing and project supply
In short: the lens is the optical core — don't gamble on image quality to save a few bucks. Zorsika projector lenses are manufactured to original factory drawings, offering a stronger overall advantage.
Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk purchasing, we recommend ordering 1 unit for testing first.
FAQ
Q: Why choose Zorsika instead of the original?
A: Zorsika lenses are manufactured to original optical drawings, with the lens group, coating, and throw ratio benchmarked item by item, and each unit resolution-tested before shipment. Compared to the original, lead times are shorter and overall value is better; compared to other replacement lenses, optical quality is backed by data.
Q: Can the lens replace the original?
A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (see the specification table above for the model) are benchmarked item by item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes, sharp imaging, and no soft edges. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, resulting in visible brightness loss and color shift. For engineering and exhibition scenarios, Zorsika is recommended.
Q: My projector isn't on the list of 2 models above — can I use the WD660?
A: The list covers verified models, not all of them. Same-brand, same-generation engineering projectors often share the same lens interface. It's safer to send a photo of the model nameplate and the original lens to Zorsika technical support for confirmation.
Q: Does the WD660 come with installation instructions?
A: Yes. The lens removal and installation steps for BenQ models like these are basically the same. Contact Zorsika sales for illustrated or video instructions for your specific model.
Q: How long is the lens warranty?
A: All Zorsika projector lenses come with a 12-month warranty. Under normal use, non-human-caused damage (such as impacts, water damage, or unauthorized disassembly) can be handled directly through after-sales service. The warranty period is based on the date on the shipment document.
Routine Lens Maintenance Tips
- Power off before changing the lens: Always shut down and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface while powered.
- Don't touch the lens elements: Fingerprints and oil will directly affect image quality. Hold the lens by the barrel, not the glass. Use an air blower to gently remove dust — don't wipe dry with a cloth.
- Focus before tightening: After installation, test focus first, then tighten the fixing screws to avoid image drift from loosening over time.
- Keep the interface clean: Dust buildup on the mount and contacts can cause poor connections. Cleaning them while changing the lens is a good habit.
