All four product families in this comparison are used for perimeter or side lighting, but they are not interchangeable. Select the module that matches the aluminum profile, required optical reach and wiring system before comparing wattage.
Comparison overview
| Product family | Primary distinction | Verify before ordering |
|---|---|---|
| 7W side-lit module | Compact module format with optical lens | Shape, bar length, connector and available mounting space |
| 12W/18W plug-in edge-lit module | Frame-mounted optical bar available in two power/length configurations | Selected wattage, exact dimensions, lens, CCT and plug-in connector |
| 13W edge-lit bar | Longer bar and different optical distribution from the compact module | Frame width, bar length, output, certification and connector |
| 20W rigid LED bar | Higher-output rigid aluminum format | Optical reach, heat dissipation space, driver capacity and mounting method |
7W side-lit module
The 7W Side-Lit LED Module is designed for perimeter installation in compact lightbox layouts. It can be the correct choice when its physical size, lens and output match the frame; “small wattage” alone does not define the suitable cabinet size.
12W/18W plug-in edge-lit module
The 12W/18W Edge-Lit LED Module mounts along the frame perimeter and projects light across the fabric. It is not a rear-panel backlight module. Buyers should select the actual 12W or 18W configuration and verify module length, optical lens, connector, color-temperature range and driver requirements.
13W edge-lit LED bar
The 13W Edge-Lit LED Bar uses a different bar length and optical layout. Compare the current product-page specification for output, certification, connector and mounting dimensions rather than treating it as a direct substitute for the 12W/18W family.
20W rigid LED bar
The 20W Rigid LED Light Bar provides higher output in a rigid aluminum format. Confirm that the lightbox depth and lens distribution can use that output evenly; more lumens can produce brighter edge bands when the optical layout is wrong.
Selection sequence
- Confirm that the system is edge-lit or side-lit.
- Measure internal frame dimensions and the available mounting channel.
- Compare module length and optical-lens specification.
- Check voltage, driver capacity, connector and linked-run limit.
- Confirm color-temperature range and certification on the exact product page.
- Test a representative frame section before ordering production quantity.
