Engineering Design Review
Use the published data as design inputs, not as a substitute for a released project drawing. Tie every interface, safety and visual-effect decision to the approved sample, wiring drawing and bill of materials.
| Design item | Published basis | Project action |
|---|---|---|
| Published design input | L-D-120-DMX512; full-colour RGB with 18 pcs SMD5050 LEDs; 120 mm diameter | Confirm on approved drawing / sample |
| Control architecture | UCS2903 listed as IC chip | Confirm on approved drawing / sample |
| Electrical basis | DC24V; 27 W; about 1.125 A per light, calculated from published voltage and power | Confirm on approved drawing / sample |

Controller, Addressing and Signal Topology
Define the exact IC or protocol, pixel grouping, controller port capacity, data direction, start address, channel order, connector pinout and termination before installation. Published control basis: UCS2903 listed as IC chip.
Power Distribution and Voltage-Drop Plan
Published electrical basis: 27 W at DC24V; planning current about 1.125 A per light, calculated from published voltage and power. Define power feeds, cable section, protection and return path from the final load and full-output scene.
Optical, Mechanical and Environmental Boundary
Published structure: full-colour RGB with 18 pcs SMD5050 LEDs; format: 120 mm diameter; protection: IP65 / IP67 waterproof options. Confirm mounting pitch, cable exit, service access, end treatment, joints and drainage for the actual installation.
Factory Acceptance and Site Commissioning
Before shipment and at site, verify channel order, addressing, test effects, full-load current, voltage under load, visible output and connector continuity against the approved sample and drawing.
OEM Order Freeze Checklist
- Final model, LED configuration, IC / protocol and pixel grouping.
- Voltage, power drawing, cable length and connector pinout.
- Dimensions, mounting interface and cable exit direction.
- IP construction, ends, joints and installation orientation.
- Controller, effect file, address map and acceptance method.
Product-Specific Control Note
The listed control IC or option is UCS2903 listed as IC chip. It determines how the controller addresses lighting effects. Confirm the final IC, protocol, controller output, data direction, connector pinout and address plan together; fixtures with similar appearance can still be incompatible at system level.
Product-Specific Installation Note
The published protection option is IP65 / IP67 waterproof options. Confirm the complete production build, including cable exit, connector, end treatment, mounting surface and any field joint. The published light structure is full-colour RGB with 18 pcs SMD5050 LEDs; mechanical clearances, heat path and mounting layout must be released with the project drawing.

Application Fit
The product page identifies applications including fairground and amusement lighting; final mounting application to be confirmed. Select the final configuration from the actual site environment, not from the product name alone.
FAQ
Can it be customized? Confirm the final electrical configuration, dimensions or spacing, cable direction, connector, IP target, controller compatibility and order quantity before production.
