Short answer: stock 5 V USB strips for plug-in fixtures that a customer installs themselves, such as shelves, cabinets, desks and display cases near a socket. Specify 12 V strips for wired installations, longer runs and projects where an electrician or installer fits a power supply. USB is the easier sell at retail; 12 V is the installer's choice.
The difference in one table
| 5 V USB (USB-A, USB-C, Remote) | 12 V | |
|---|---|---|
| Power | Any USB charger, laptop or power bank | A 12 V DC power supply, sold separately |
| Who installs it | The end customer | An installer, electrician or millworker |
| Typical use | Shelves, cabinets, desks, display cases, behind a TV or mirror | Kitchens, joinery, built-in furniture, longer or multiple runs |
| Run length | Shorter runs | Longer runs |
| Selling point | Plug in and it works | Hidden, permanent, wired to a switch or driver |
Why voltage matters for run length
At a low voltage, a long strip draws more current for the same light, and some of the voltage is lost along the copper. On a long 5 V run the far end can look dimmer than the start. A 12 V strip carries the same light with less current, so it holds its brightness over a longer run and suits installs where one power supply feeds several strips. For short plug-in fixtures, 5 V is simpler and the difference doesn't show.
Choosing for a retail shelf
- USB-A works with the chargers most customers already own, so it is the widest fit.
- USB-C suits newer chargers, laptops and power banks, and customers who have moved to USB-C.
- Remote adds a dimmer, so a customer can set the brightness without reaching into the cabinet. It is an easy upsell for display cases and bedrooms.
- 12 V belongs next to power supplies and installation accessories, for trade customers and confident DIYers.
Choosing for a project
For built-in work, start from the power: where the supply will sit, how many runs it feeds and how the lighting is switched or dimmed. That usually points to 12 V. Use USB strips for loose furniture, freestanding display cases and anything the client may move later.
What every Linework strip shares
Whichever voltage you choose, every Linework strip is a dotless COB strip with CRI 90 or more, cuts every 5 cm at the marked points, has an adhesive back and is for indoor, dry locations only.
