LSH-646 Plaster-in LED Corner Profile
LSH-646 for architectural corner lighting. See the model-specific section drawing; final dimensions and configuration require confirmation.
Item No.: LSH-646
1. Main Features
LSH-646 is a plaster-in corner led aluminum profile for architectural corner lighting. The catalogue shows a corner-shaped section with perforated fixing wings. Use its individual cross-section to assess the architectural detail, fixing area and LED tape arrangement.
Confirm the outward corner orientation. A compact LED cavity is shown between two sloping mounting wings. A product photograph is useful for comparing shape, but the final installation should follow an approved drawing and a physical sample. Confirm the complete profile, diffuser, LED tape and mounting combination before ordering.
- Section-specific design: The visible structure combines a corner-shaped section with perforated fixing wings.
- Architectural coordination: Check inside versus outside corner orientation and board support.
- LED and cover selection: Compare the complete tape and diffuser combination for fit, appearance and access. A visible cover shape does not identify its material or transmission.
- Order consistency: Approve the same profile version, finish, cover and accessories for the sample and bulk order.

3. Applications
Ceiling and wall corners
Review the corner orientation against a section of the wall and ceiling. Mounting wings must have sufficient support.
Corridor transitions
Use straight corner runs to define an architectural edge. Check how joints and cable exits are concealed.
Retail feature details
Assess the visible line from customer viewing positions. Test the intended strip and cover before committing to a display installation.
These are proposed applications based on the section geometry. Suitability for moisture, outdoor exposure, fire-rated construction or other special conditions requires a separate verified specification.
4. How to Choose the Right Profile
- Start with this section: Confirm the outward corner orientation. A compact LED cavity is shown between two sloping mounting wings.
- Check the mounting detail: Show the board thickness, support, fixing positions and finished plaster or paint line. Confirm whether the profile is installed before or after the board and finish.
- Test LED tape fit: Measure the usable bed and include the PCB, adhesive, solder pads, cable and connectors. Do not order tape by the model number alone.
- Review light appearance: Test the chosen LED density, diffuser and surrounding surfaces. A dot-free appearance depends on the complete arrangement.
- Plan access: Identify how the diffuser, tape, connector and driver can be reached after installation. Confirm cable routes before closing the ceiling.
5. Quality Checks Before Bulk Purchasing
Evaluate a sample of LSH-646 against the latest drawing before approving a bulk order. A lower price can reflect a different version, cover, wall thickness, finish, included accessory set or packaging specification.
- Compare external dimensions, the usable light chamber, cover locking features and straightness with the agreed tolerances.
- Measure wall thickness at agreed points. Do not replace a measured specification with labels such as heavy-duty or premium.
- Check the cover for fit, consistent appearance and removal access. Approve the exact material and optical finish in writing.
- Inspect the exposed face under the intended lighting. Look for scratches, coating defects and finish inconsistency across lengths.
- Build one real mounting sample. Check fixing support, the finishing edge, corner alignment and cable access.
- Run the intended LED configuration to evaluate thermal behaviour and visual consistency under the proposed conditions. Aluminum alone does not establish a maximum permitted wattage.
- Agree on carton protection, length identification and version labels. Keep the approved sample and specification with the order.
6. Customization and Project Support
For a project or OEM enquiry, send the model and version, a section of the wall or ceiling, intended lengths and quantities, LED tape details and the required appearance. A CAD file or marked-up sketch helps identify whether this section fits or another product should be reviewed.
