Compatible Models: 4 Leli Projectors (with Brightness, Resolution, Zoom Ratio)
Below are the verified compatible models for WD640 (Leli projectors), with brightness, resolution, and zoom ratio listed for each:
| Projector Model | Brightness | Resolution | Zoom Ratio |
|---|---|---|---|
| CL6600U | 9000 lumens | WUXGA 1920×1200 | 0.5, 0.68-0.80 |
| RL-M9U | 9000 lumens | WUXGA 1920×1200 | 1.6 |
| RL-M8U | 8000 lumens | WUXGA 1920×1200 | 1.6 |
| RL-M7U | 7000 lumens | WUXGA 1920×1200 | 1.6 |
Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (refer to the model nameplate/manual for accuracy); lens compatibility is subject to the body interface and optical structure. For models not on the list, please contact Zorsika technical support for confirmation.
What Zorsika Lenses Offer You
For engineering lenses like the WD640, Zorsika benchmarks each item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes, sharp imaging, and no blurring at the edges — ready to use upon installation.
Zorsika's equivalent replacement model is compatible with 4 models including Leli CL6600U, RL-M9U, RL-M8U, and RL-M7U; enter WD640 in the Zorsika official website query system to view 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 coating at the same level as the original, reducing light loss
- Stable Supply: Supports bulk procurement 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 according to original drawings, offering a comprehensive advantage.
Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk procurement, we recommend obtaining 1 unit for testing.
What to Watch Out for When Replacing a Lens
- Power off before replacing the lens: Before removing or installing the lens, be sure to shut down and wait for the cooling fan to stop, to avoid damaging the interface by operating with power on.
- Don't touch the lens elements: Fingerprints and oil stains directly affect image quality. Hold the lens by the barrel, not the glass; use an air blower to gently remove dust — do not wipe dry with a cloth.
- Focus before tightening: After installation, perform a focus test first, then tighten the fixing screws, to avoid image drift from loosening over long-term use.
- Keep the interface clean: Dust accumulation on the mount and contacts can cause poor contact. Cleaning them while replacing the lens is a safer practice.
Frequently Asked Questions
Q: My machine isn't on the list of 4 models above — can I use the WD640?
A: The list covers verified models, but it doesn't represent all. Engineering projectors of the same brand and generation often share the same lens interface. It's safer to take photos of the body nameplate and the original lens and send them to Zorsika technical support for confirmation.
Q: Can the lens replace the original one?
A: The lens is the core of the projector's optical path, directly determining clarity and color. Zorsika lenses (model numbers as in the specification table above) 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 blurring at the edges; ordinary replacement lenses often use standard glass elements with insufficient coating layers, resulting in brightness loss and color shift visible at a glance. For engineering and exhibition scenarios, Zorsika is recommended as the priority.
Q: Why choose Zorsika instead of the original?
A: Zorsika lenses are manufactured according to original optical drawings, with the lens group, coating, and throw ratio benchmarked item by item, and each unit undergoes resolution testing 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: What if the lens doesn't match the screen size?
A: First confirm the model's lens interface and optical axis position, then select a lens with the corresponding throw ratio based on the actual installation distance. If unsure, send the installation distance and screen size to Zorsika technical support, and we'll help you choose.
Q: Does the WD640 come with installation instructions?
A: Yes. The lens removal and installation steps for Leli models like these are basically the same. Contact Zorsika sales to obtain illustrated or video instructions for the corresponding model.
Q: How long is the lens warranty period?
A: All Zorsika projector lenses come with a 12-month warranty; for normal use and non-human-caused damage (such as impact, water damage, or unauthorized disassembly), you can contact after-sales service directly. The warranty period is based on the date on the shipment document.
