24V backlight boards for illuminated advertising
The SL-BL007-B020 catalogue listing covers a rectangular LED backlight board for advertising lightboxes. It combines 24 SMD2835 LEDs with a 300 × 75 × 10mm format, specified 200–250 lm output and a 120° beam. The detailed parameter table lists DC 24V input and 2.4W power per board.
For sign-making contractors and lighting-component distributors, quote the board version and project quantity together. Provide the sign enclosure drawing, display-face material, required colour temperature and destination so the boards, joint parts and supply configuration can be checked before bulk procurement.

Specify the board behind the advertising face
The product illustration shows the board as a backlight source for a lightbox. Define the board positions from the enclosure and graphic dimensions, then evaluate the proposed spacing with the actual diffuser and face material. Confirm the chosen white-light version before approving the sample configuration.
Review the board and joint construction
The board image labels a 300mm long edge and shows the LED face, reverse side and terminals. The panel illustration shows neighbouring boards connected using metal bridges and screws. Provide the assembly drawing so the required connections and fixing arrangement can be specified for the order.
Make the wholesale bill of materials clear
State the number of individual boards, number of lightboxes and any joint components or matching power units required. Use the listed DC 24V board input when defining the electrical configuration, and confirm circuit grouping and feed wiring for the finished sign. Include the catalogue reference in repeat-order enquiries to identify the requested board version.
Sign-fabricator procurement questions
What does the quoted quantity refer to?
Specify whether the quantity is for individual SL-BL007-B020 boards or for the components required by a number of finished signs. List joint parts and power units separately so the quotation states the complete supply scope.
How do I select the matching power configuration?
The detailed board specification is DC 24V. Provide the board count and wiring layout so total panel demand, circuit grouping, feed connections and power-unit requirements can be checked together.
Can I use the same specification for repeat sign projects?
Keep the catalogue reference, colour-temperature version, approved board layout and bill of materials with the project. Quote those details when requesting repeat supply, and confirm any changes in enclosure or face construction.
Are sample boards and wholesale pricing available?
Samples are available, with configuration, cost and shipping confirmed first. Wholesale supply starts at 20 pcs, and higher quantities receive lower unit prices. Include the destination and required components with the enquiry.
What lead time applies to OEM or private-label enquiries?
The standard lead time is 12–18 days. OEM, ODM and private-label enquiries are supported; custom requirements, scope and production schedule are confirmed for the order. Transit time is confirmed separately.
