How to Choose a UCS1912 RGB Linear Pixel Tube for Facade and Entertainment Projects
A practical B2B guide to evaluating a DC24V UCS1912 RGB linear pixel tube by viewing distance, pixel allocation, power planning and installation.
Begin with the facade effect, not the data-sheet label
A linear pixel-tube project can disappoint for two opposite reasons: the light looks like separate bright blocks from the street, or the animation is too fine to be recognised at the intended distance. For facades, stages, hotels, KTV and bars, start with the viewing distance, the direction of the tube and whether the design needs broad colour flow, segmented chasing or a more detailed pixel pattern.
What the published 1 m tube configuration means
The published tube is 1000 x 50 x 45 mm, uses DC24V, SMD5050 RGB LEDs and a 180-degree beam angle. The page lists 48 LEDs/m and an 11.52 W/m maximum consumption. A one-metre module helps quantity take-off and repetitive facade layout; its 180-degree optical distribution makes the orientation of the exposed side and the mounting plane part of the visual decision.
Pixel allocation and UCS1912 cascade control
The page title says 16 pixels while the captured parameter record says Pixel QTY 8. These values conflict, so neither should be treated as the approved production allocation. UCS1912 is a cascade-pixel control architecture: confirm the final pixel grouping, data direction, controller compatibility, port allocation and content mapping before samples or production. Do not explain this product as individually assigned DMX addresses unless a selected controller explicitly maps it through DMX or Art-Net.
DC24V load planning and voltage-drop logic
At the published maximum 11.52 W/m, the theoretical current is 11.52 W/m divided by 24 V = 0.48 A/m. A 100 m quantity therefore begins with 100 x 11.52 W/m = 1152 W, and 1152 W divided by 24 V = 48 A. This is a load-planning starting point, not a single-power-supply instruction. Divide large installations into circuits and set power feeds, cable size and margin from the approved drawing and actual effect load.
Cover, mounting and environmental boundary
With comparable line resistance, voltage drop can be understood as current multiplied by line resistance. DC24V generally needs less current than a lower-voltage product at the same power, but it does not remove voltage drop. Cable length, conductor size, connectors, power-feed positions and the programmed load remain relevant, so measure loaded voltage at the end of each approved circuit. The page lists transparent and milky-white covers plus silver-white or black aluminium profile options; choose the visible finish and mounting direction from the facade surface and daytime appearance.
Quick selection table
| Broad colour flow or facade contour | Evaluate the 1 m tube where the viewing distance supports visible linear modules. |
|---|---|
| Fine pixel graphics or close viewing | Confirm the final pixel allocation first; the published title and captured record do not agree. |
| Regular bays, columns or rooflines | Use the 1000 mm module as a layout and quantity-planning unit. |
| Long or multi-zone installation | Start with 11.52 W/m maximum and 0.48 A/m theoretical current, then divide circuits. |
| Daytime visible facade | Select transparent or milky-white cover and silver-white or black profile from the surface and visual target. |
| Programmable RGB effects | Confirm UCS1912 grouping, data direction, controller compatibility, port allocation and mapping. |
Where this LIKELIGHT configuration fits
LIKELIGHT publishes this configuration with DC24V, UCS1912, SMD5050 RGB, 48 LEDs/m, 180-degree beam angle, 1000 x 50 x 45 mm structure, 11.52 W/m maximum consumption and CE/RoHS information. The listed applications include stage, KTV, DJ, bar, home, hotel and indoor or outdoor decoration. It is a useful starting point for repeated one-metre colour lines and segmented pixel effects; projects requiring a confirmed fine-pixel layout must first close the final pixel allocation.

Information to provide before quotation
For a reliable quotation, provide the elevation or mounting drawing, total length and length per zone, main viewing distance, effect reference, final pixel requirement, controller and data interface, cover and profile colour, mounting orientation, exposure conditions, cable direction, sample requirement and delivery date. These inputs let LIKELIGHT assess the visual segmentation, circuit plan and connection approach as one project.
