How to Choose 80mm DMX RGB Pixel Lights for Facades, Signs and Entertainment Projects
A practical B2B guide to choosing 80mm DC24V DMX RGB pixel lights by viewing distance, fixture spacing, control planning and installation conditions.
Start with the visual task, not the fixture
A pixel-point project can look under-resolved when the fixtures are too far apart, but it can also become expensive and hard to maintain when too many points are used. For building outlines, channel letters, stage walls and amusement installations, begin with the viewing distance, the intended animation and whether the light points themselves should be visible.
What the 80mm format changes
This published configuration is an 80mm RGB pixel light with 12 SMD3535 LEDs, DC24V input and DMX control. An 80mm luminous point is a visible design element, so it suits graphic outlines, signs and decorative arrays more naturally than applications that require an uninterrupted linear light line.
The page lists IP20 and IP65 options. IP20 can be considered for dry indoor installations; splash-prone or outdoor work should evaluate the IP65 version together with end treatment, connectors, cable exits and the complete mounting method.
DMX control and power planning
DMX512 is useful when a project needs organised zones and programmed colour changes. In RGB operation, a controlled point often uses three colour channels, but the final channel mode, addressing and controller capacity must follow the confirmed fixture and controller configuration. Do not assume the 12 LEDs shown inside the housing create 12 separately addressed DMX pixels.
The published rating is 2.88W per fixture. A 100-fixture concept therefore starts with 100 x 2.88W = 288W; at DC24V, 288W / 24V = 12A. This is a theoretical planning value. Divide real installations into suitable power circuits and allow for cable size, connector count, programme content and the loaded voltage measured at the end of each circuit.
DC24V reduces current compared with a lower-voltage product of the same power, which can help circuit planning. It does not remove voltage-drop risk: with comparable line resistance, voltage loss follows current multiplied by line resistance. Cable length, conductor size, connections and feed locations still determine the field result.
Mounting, protection and service access
Before fixing the layout, mock up a small area at the intended viewing distance. Use the result to choose point spacing and mounting pitch. The 80mm housing needs enough structure for alignment, cable routing and replacement; a drawing should show fixture orientation, branch points and service access before production.
Quick selection table
| Readable sign outlines or decorative grids | Evaluate 80mm points after a viewing-distance mock-up |
|---|---|
| Smooth continuous light line | Consider a linear fixture or a denser point layout instead |
| Programmed colour zones | Confirm DMX mode, addresses and controller plan |
| 100 fixtures | Start power planning from 288W and 12A at DC24V |
| Dry indoor installation | Assess the IP20 configuration with the mounting structure |
| Moisture-prone or outdoor installation | Assess IP65 with connectors, cable exits and complete installation details |

Information to prepare for quotation
Send the elevation or installation drawing, total fixture quantity and zone quantities, main viewing distance, target effect reference, indoor/outdoor environment, required protection option, controller information, cable direction and requested sample or delivery date. These details allow point spacing, control zones, power circuits and connection methods to be evaluated as one project system.
