LSH-4020DD Double-wing plaster-in LED Aluminum Profile
LSH-4020DD is a double-wing plaster-in LED aluminum profile with perforated fixing wings on both sides of a central diffuser channel. The catalog shows a 20 mm height and 80 mm overall width. It is a candidate for straight ceiling slots, corridor light lines and recessed wall accents.
The 40 mm face dimension helps distinguish this section within the range. Specify the drawing together with the item number when requesting a quotation. The aluminum housing and cover form part of a lighting assembly; LED strip, driver, wiring and installation details must be selected for the project.

[TO CONFIRM: Catalog dimensions are provisional readings. Confirm units, tolerance and final CAD. Do not use overall flange width as the drywall cutout.]
Selection and compatibility
Check the flange elevation and channel orientation on the section drawing. Models with similar face widths can have different body depths and fixing levels.
This is a wider-face candidate where the lighting detail should read as a broader band. Width alone does not establish output: compare strip layout, diffuser transmission, power and viewing distance in a lit sample.
The catalog shows a 20 mm overall height. Compare the available recess depth with the shallower 13 mm family, and confirm how much space remains after accounting for the strip and cover.
Application ideas
Consider LSH-4020DD for straight ceiling slots, corridor light lines and recessed wall accents. These are proposed applications based on the visible structure, not verified project references. For an office or corridor, coordinate the light line with ceiling joints and service access. For a retail or hospitality interior, review the unlit appearance and glare from the actual viewing positions.
A profile photograph cannot establish ingress protection, emergency-lighting suitability, fire performance or photometric compliance. Where a specification requires one of these properties, obtain documentation for the complete assembly.
Installation planning
- Approve the profile section, board thickness, recess and finished light opening on a project drawing.
- Dry-fit a sample with the selected cover, strip, end caps and cable entry. Check removal access.
- Fix the profile to a suitable support using the agreed flange detail. Do not rely on finishing compound alone.
- Protect the LED channel and diffuser seat during plastering. Use the joint-reinforcement and compound system specified for the construction.
- After finishing and cleaning, install and test the strip, wiring and cover according to the approved assembly instructions.
[TO CONFIRM: Add your confirmed installation drawing, fixing method, screw spacing, board detail and accessory list. Generic sequence only; not a model-specific installation instruction.]
Quality checks before ordering
For LSH-4020DD, begin with the dimensional checks shown above. Compare the production section with the approved drawing, check straightness and inspect the diffuser engagement along the full length. Look for burrs at cut ends and blocked flange perforations.
Check the flange elevation and channel orientation on the section drawing. Models with similar face widths can have different body depths and fixing levels. Use a lit sample to assess spotting, cover movement and the finished plaster edge. Record the agreed visual acceptance criteria before bulk production. Heating depends on the strip, thermal contact and installation environment; a thicker-looking profile is not proof of a permitted wattage.
Customization, quotation and payment
Send the item number, required lengths, quantity per length, housing finish, cover preference and destination. Include your strip dimensions and any solder pads or connectors, as well as the wall or ceiling detail. We can review whether the illustrated section is suitable or whether a structural change needs assessment.
Request a quotation that separates the aluminum profile, cover, end caps, machining, packaging and freight. Confirm whether LED strips and drivers are included. Tooling, samples, payment stages, currency, shipping term and delivery schedule must be agreed in the written quotation.
[TO CONFIRM: Insert confirmed MOQ, sample charge, lead time, payment terms, warranty and contact or enquiry form. Do not publish unconfirmed commercial terms.]
Frequently asked questions
What does the item number tell me?
Use LSH-4020DD as an identifier. The drawing defines the geometry; model digits and suffixes are not a substitute for an approved dimensioned section.
Which LED strip fits?
The catalog marks an internal span of 37 mm. Confirm the mounting surface, connector clearance and cover engagement with a physical sample.
Will the finished line be dot-free?
That depends on LED spacing, mixing distance and diffuser. Approve a lit sample using the intended strip.
Can this be ordered for an outdoor installation?
No outdoor or IP rating is established by these catalog images. Confirm a tested assembly if the project requires one.
