Zorsika WD488 Projector Lens for Hualu HL-DU700C HL-DU800C HL-DU900C HL-DU1050C HL-DU750C and 8

WD488 is a lens compatible with engineering projectors from brands such as Hualu. This article compiles a list of its 8 compatible projector models and selection notes.

Lens Specifications at a Glance

The above specifications come from the Zorsika product database. Contact sales for the complete technical datasheet.

WD488 Model Compatibility List (8 Models, with Brightness/Resolution/Zoom Ratio)

The following are verified compatible models for WD488 (Hualu projectors), with brightness, resolution, and zoom ratio listed for each:

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, contact Zorsika technical support for confirmation.

Same Specifications — Why Choose Zorsika

For engineering lenses like the WD488, Zorsika benchmarks each item against original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes for sharp imaging and no edge blurring — ready to use right after installation.

Zorsika's same-spec alternative model is compatible with 8 models including Hualu HL-DU700C, HL-DU800C, HL-DU900C, HL-DU1050C, and HL-DU750C; enter WD488 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 leaving the factory, with MTF data available
• Coating process: Lens coatings at the same level 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 dollars. Zorsika projector lenses are manufactured to original drawings and offer comprehensive advantages.

Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk purchasing, we recommend obtaining 1 unit for hands-on testing.

What to Watch Out for When Replacing a Lens

• Power off before replacing 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 on.
• Don't touch the lens elements: Fingerprints and oil 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 first, then tighten: After installation, perform a focus test before tightening the fixing screws to prevent image drift from loosening over time.
• Keep the interface clean: Dust on the mount and contacts can cause poor contact. Cleaning them while replacing the lens is a safer practice.

Frequently Asked Questions

Q: My projector isn't on the 8-model list above — can I use the WD488?

A: The list covers verified models, not all models. Engineering projectors of the same brand and generation often share the same lens interface. For confirmation, send a photo of the model nameplate and the original lens to Zorsika technical support.

Q: Can this lens replace the original one?

A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (model numbers in the specification table above) benchmark each item against original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes for sharp imaging and no edge blurring. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is recommended.

Q: Why choose Zorsika instead of the original?

A: Zorsika lenses are manufactured to original optical drawings, with lens groups, coatings, and throw ratios benchmarked item by item, and each unit undergoes resolution testing before leaving the factory. Compared with the original, lead times are shorter and overall value is better; compared with 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 appropriate 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: Is there an installation guide for the WD488?

A: Yes. The lens removal and installation steps for Hualu models 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. For normal use and non-human-caused damage (such as impacts, water damage, or unauthorized disassembly), contact after-sales service directly. The warranty period is based on the date on the shipping document.
