Square LED panels for advertising-lightbox backlighting
Specify a 300 × 300mm square backlight board for illuminated advertising displays. The panel carries 96 SMD2835 LEDs and is rated at 14.4W, with DC 24V input and 1350–1450 lm specified output. SL-BL007-A080 is the catalogue ordering reference for this listing.
For sign fabricators and lightbox manufacturers, the 300mm square format is a practical starting point for the panel layout. Provide the usable enclosure dimensions, graphic or diffuser material and desired white-light version so the board quantity, connections and power supply can be specified together.

Fit the board layout to the lightbox
Measure the usable back-panel width and height, frame obstructions and feed positions before selecting the board count. The photographs show a square PCB with its rear face and terminal details. Include a layout drawing with the enquiry so connection components and circuit grouping can be confirmed for the actual assembly.
Assess the lightbox depth, diffuser and printed face with a representative sample. Panel spacing and the display material affect the final illuminated appearance; select the layout against the finished graphic.
Packing and production-order preparation
The packing photographs show stacked square boards with protective sheets and an outer carton. Specify the required board quantity, protective packing and carton labelling for the shipment. Power supplies, feed leads and connection parts should be itemised in the quotation.
Square backlight-panel purchasing questions
Is the A080 reference an 80-LED panel?
The parameter sheet specifies 96 SMD2835 LEDs. Use SL-BL007-A080 as the catalogue ordering reference, together with the 300 × 300mm dimensions and required colour temperature.
What supply configuration should I request?
The detailed parameter table specifies DC 24V. Share the total board count and panel drawing so the power unit, wiring and circuit grouping can be confirmed for the assembly.
Can I choose a white-light version for printed graphics?
The listed white-light order range is 3000–8000K. Specify the colour temperature required for the graphic and evaluate a sample behind the intended diffuser; a colour-temperature control is not specified.
Can I test a panel before buying in volume?
Samples are available. Provide the lightbox dimensions, face material and required version to define the sample configuration. Sample cost, quantity and shipping are confirmed separately.
What are the wholesale supply terms?
Orders start at 20 pcs, with lower unit prices at larger quantities. Standard lead time is 12–18 days. OEM, ODM and private-label enquiries are supported; custom scope and transit time are confirmed with the order.
