3mm and 5mm COB series for slim aluminum channels, display cases, shelves, and other spaces where standard boards are too wide.
Two narrow PCB options for channels that standard COB cannot enter cleanly.
Dense enough for compact linear work without moving into wider-board COB.
Power range matched to slim-profile and display-oriented installations.
Cut interval changes with width and voltage option, so confirm the exact model early.

Use this table to screen voltage, color direction, structure, and project fit before narrowing the final model.
| Item | Quote direction | Commercial note |
|---|---|---|
| Light engine | Catalog-backed flexible COB strip | Aligned with the Wismart COB Series 2026 catalog so buyers can compare against a defined product family. |
| Voltage option | DC 12V / 24V narrow-board options | Final driver and run-length plan should be confirmed before quotation closes. |
| Color / CCT direction | 3000K-6000K single-color white, CRI 90+ | Lock the exact white or color-control direction before sample preparation. |
| Output positioning | 3mm and 5mm COB strip options for compact slots | Use this as the first buyer-facing output range before final model confirmation. |
| Structure direction | Ultra-narrow PCB width for slim profiles and tight installation details | The correct choice depends on installation width, cut interval, color-control need, and power planning. |
| Typical project fit | Cabinet, shelf, display case, narrow aluminum profile, and compact architectural details | Use the application description to guide the buyer into the right family before SKU expansion. |
These catalog-backed rows help buyers narrow the correct model before sample approval and quotation.
| Model No. | Voltage | Power/m | LEDs/m | Color | CRI | Cutting Section |
|---|---|---|---|---|---|---|
| WS-COB-3mm | DC 12V / 24V | 7W | 400 led/m | 3000K-6000K | 90+ | 1cm / 2.5cm |
| WS-COB-5mm | DC 12V / 24V | 9W / 10W | 320 / 480 led/m | 3000K-6000K | 90+ | 2.5cm / 5cm |
Use these checkpoints to align samples, drawings, packaging, and production details before the order moves forward.
The real profile or groove width should decide 3mm versus 5mm before any other comparison.
Do not assume the narrowest board is always right if the scene needs stronger output or easier installation.
Compact channels often expose cut spacing and wire exit decisions earlier than standard installations.
Send the real profile drawing or slot width with the inquiry so the sample can be judged correctly the first time.
Use this checklist to confirm the commercial and technical points buyers normally settle before sample or quotation.
Measure the real inner-channel width before selecting 3mm or 5mm, not after the sample arrives.
Confirm whether the project needs 3mm minimum width or if 5mm can provide a better output compromise.
Check the cut interval against the visible section lengths because narrow layouts often have tighter tolerance.
Review cable-out direction and installation access early, because compact channels are less forgiving during wiring.
Use these request blocks to ask for datasheet review, drawing confirmation, sample planning, and OEM packing support.

Plan SamplesReserve space for private label, barcode, outer-carton, and mixed-SKU packing requirements.
Discuss OEM PackingThese FAQs focus on the questions buyers normally resolve before they move from category screening to model selection.
Start from channel width and installation tolerance first. If the profile can accept 5mm, it may offer a more relaxed supply and output path than forcing 3mm.
No. It also fits displays, showcases, fine joinery, and other compact-profile projects where standard-width COB is too wide.
Usually the design tradeoff is tighter structure first, then output. That is why width and brightness target should be confirmed together.
Only when width is the real constraint. If width is not driving the job, the low-voltage COB page is usually the better starting point.
Send the voltage option, target output, color direction, quantity, and application so the team can align the correct model faster.
