170mm LED sign modules for compact display layouts
Select a compact three-LED light source for an illuminated-sign or advertising-display assembly. SL-BL102-3L measures 170 × 21.5 × 13mm and is specified at 3.5W ±10%, with 350 lm ±10% output, 10 × 60° lenses and a 24V DC input.
For sign fabricators and component wholesalers, the short module envelope is useful when assessing limited mounting space or a layout using several lengths. Send the frame dimensions, planned positions and chosen white-light version to confirm the modules, fixing parts and electrical supply scope.

Check the short module against the mounting space
Use the 170mm length, 21.5mm width and 13mm complete height when checking the frame drawing. The photographs show individual lenses and slotted fixing areas for installation planning.
The construction illustration identifies a 1.6mm aluminium substrate. Include the fixing positions and frame profile to confirm the hardware for the quoted assembly.
Optics, connection parts and sample layout
The specified lens angle is 10 × 60°. Assess the module positions with the intended enclosure, graphic and diffuser, then review a sample assembly before approving production quantities.
The connection photographs illustrate board-end DC sockets. Send the module quantity, wiring route and required connecting parts so the leads, fixing components and 24V power units can be itemised.
White-light order choices and mixed-length projects
Four ranges are listed for ordering: 2800–3200K, 3700–4300K, 4700–5300K and 6500–7500K. Specify the selected version with SL-BL102-3L so the sample and production order use the confirmed configuration.
The series illustration includes the three-, six- and eighteen-LED versions. For a project using several lengths, provide a model-by-model quantity list and review each bar’s dimensions, output and power.
Packing and wholesale procurement
The original packing graphic shows individual protection and cartons. Confirm the packing specification, units per carton and supplied components with the order quotation.
Wholesale quantities start from 20 pcs, with lower unit prices at higher volumes. Samples are available and standard lead time is 12–18 days. OEM, ODM and private-label enquiries are supported, with sample shipping, custom production scope and transit time confirmed separately.
Questions for buying 170mm LED sign modules
What is the power rating of this compact module?
