WB351 Compatible Model List (4 Models with Brightness/Resolution/Zoom Ratio)
The following are the verified compatible models (LEXI projectors) for the WB351, each with brightness, resolution, and zoom ratio:
| 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 (subject to the model nameplate/manual); lens compatibility is determined by the body interface and optical structure. For models not listed, please contact Zorsika technical support for confirmation.
What the Zorsika Lens Offers You
Zorsika provides replacement lenses for the WB351 with identical specifications to the original, with key parameters matched item by item against the original, supporting bulk project procurement and supply.
The Zorsika equivalent replacement model is compatible with 4 LEXI models including CL6600U, RL-M9U, RL-M8U, and RL-M7U; enter WB351 in the Zorsika official website query system to view the full list of compatible models.
- Optical Alignment: Focal length, throw ratio, and lens groups matched to original specifications
- Resolution Testing: Each lens individually tested before shipment; MTF data available
- Coating Process: Lens coatings on par with the original, reducing light loss
- Stable Supply: Supports bulk procurement and project supply
In short: The lens is the optical core—don't gamble picture quality for a price difference. Zorsika projector lenses are manufactured to original drawings, offering an overall advantage.
Note: Actual imaging performance is affected by projector condition and installation environment. We recommend testing one unit before bulk procurement.
What to Watch Out for When Replacing the Lens?
- Power off before replacing the lens: Always shut down the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface with power on.
- Don't touch the lens glass: Fingerprints and oil stains directly affect image quality. Hold the lens barrel, not the glass; use an air blower for dust and avoid dry wiping with cloth.
- Focus before tightening: After installation, test focus first, then tighten the locking screws to prevent loosening and image drift over time.
- Keep the interface clean: Dust on the mount and contacts can cause poor connectivity; clean them when replacing the lens for reliability.
Frequently Asked Questions
Q: My projector is not in the 4 models listed above. Can I use the WB351?
A: The list covers verified models but is not exhaustive. Engineering projectors of the same brand and generation often share the same lens mount. For certainty, send photos of the nameplate and original lens to Zorsika technical support for confirmation.
Q: Can this lens replace the original one?
A: The lens is the core of the projection optical path, directly determining sharpness and color. Zorsika lenses (model shown in the specification table above) are matched item by item against original optical parameters (focal length, throw ratio, lens groups), with consistent coating processes, delivering sharp images without edge blur. Ordinary replacement lenses often use standard glass with insufficient coating layers, making brightness loss and color shift immediately visible. For engineering and exhibition applications, Zorsika is the recommended choice.
Q: Why choose Zorsika instead of the original?
A: Zorsika lenses are manufactured to original optical drawings, with lens groups, coatings, and throw ratios matched item by item, and each lens undergoes resolution testing before shipment. Compared to the original, we offer shorter lead times and better overall value; compared to other replacement lenses, our optical quality is backed by data.
Q: What if the lens doesn't match the projected image size?
A: First, confirm the lens mount and optical axis position of your projector, then select the appropriate throw ratio lens 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: Is there an installation guide for the WB351?
A: Yes. The lens removal and installation steps for LEXI models are largely consistent. Contact Zorsika sales to obtain 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, unauthorized disassembly), contact our after-sales service directly. The warranty period is based on the shipping document date.
