Permanent WS2811 Eaves Lights: Freeze Voltage, Branch Load and Service Access Before Installation
Quick decision
Do not order a permanent roofline by total metres alone. Freeze one voltage version, confirm that 2W is the per-point rating, map every WS2811 point in installation order, and divide the roof into powered service zones that can be reached after completion.
Published facts and evidence boundary
| Parameter | Published or derived value |
|---|---|

| Light and control | SMD5054 RGB; WS2811 cascade pixel |
| Body | 35x30mm published size; product drawing shows detailed housing dimensions |
| Voltage wording | Title lists 24V/36V; specification row lists DC24V |
| Published power | 2W in product title; bind it to the ordered point version |
| Protection | IP68 listed for the light body |
Start with daytime concealment and nighttime spacing
Permanent eaves lighting has two visual states. By day, housing, cable and track should sit consistently under the soffit; at night, point spacing and distance from the wall determine whether the façade shows separate pools, a continuous rhythm or uneven scallops. The 35x30mm body describes the module, not the installation spacing.
Build one representative bay containing a straight run, an inside corner and the actual fascia color. Review it from the driveway and street at night, then inspect housing visibility by day. Record point pitch, wall offset and corner treatment from the approved bay rather than copying spacing from a catalogue photo.
Resolve the 24V/36V wording before tracks are drilled
The page identifies LC3530-WS2811, SMD5054 RGB, a 35x30mm body and IP68. Its title contains 24V/36V and 2W, while the parameter row states DC24V. These entries describe a family or page mismatch; they cannot be combined into one electrical specification.
The production row must name one voltage, confirm 2W per point, define shell and cable color, point spacing, cable length between points, input/output conductor assignment, connector, data direction and IP construction. The sample, controller profile and power drawing must carry that same code.
Convert point count into branch load before choosing power locations
If 2W is confirmed per point, theoretical current is 2W/24V = 0.083A per point or 2W/36V = 0.056A per point. Fifty points equal 100W: about 4.17A at 24V or 2.78A at 36V before cable loss, connector heating and design margin.
This comparison explains why voltage choice changes current, but it does not establish a maximum chain or feed distance. Divide roof elevations at accessible locations, fuse branches appropriately and measure the last point under the approved full-load scene. Keep drivers and injection joints reachable without removing finished soffit panels.
Map the WS2811 data path separately from power branches
WS2811 is a cascade-pixel architecture, so animation planning follows point count, installation sequence, data direction and controller-port mapping. It should not be described as one native DMX address per light unless an external controller explicitly maps the pixels into DMX or Art-Net channels.
The current page does not publish point spacing, conductor assignment, pinout, port limit or signal distance. Freeze those on a signed string sample. Label the first and last point of every roof zone, document how data crosses corners, and define the replacement orientation so one failed service action does not reverse the chain.
IP68 at the light body is only one outdoor boundary
The product row lists IP68, but the installed system also includes cable entries, connectors, cut or splice points, driver enclosures, wall penetrations and drainage paths. A waterproof point does not make an unsealed field splice or trapped soffit cavity waterproof.
Approve the track or clips around the actual 35x30mm housing, preserve drip paths and provide strain relief at corners. Mark service loops and removable sections in the elevation drawing. Permanent installation value comes from recoverable maintenance, not only from a high body rating.
Conditional project decision table
| Project condition | Decision and evidence |
|---|---|
| Visible individual light pools | Set point pitch and wall offset with a night mock-up, not the 35mm body dimension. |
| Long color chase | Freeze point order, data direction and controller-port map before cable production. |
| Covered interior soffit | Use the signed housing version and keep drivers and joints accessible. |
| Exposed roof edge | Combine the IP68 body with sealed connectors, drainage and rated enclosures. |
| Many points on one elevation | Calculate from confirmed 2W/point, split branches and test the loaded last point. |
| Existing WS2811 show controller | Verify voltage, color order, point count and connector pinout on the signed string. |
LIKELIGHT LC3530-WS2811 as a permanent roofline sample
This model fits addressable RGB eaves and soffit projects that need a compact 35x30mm point, WS2811 cascade control and a protected light body. The 2W title value allows transparent branch comparison after the production version confirms its voltage and per-point basis.
It is not a complete roofline system by itself. LIKELIGHT should release a signed sample string, dimensional drawing, voltage/power row, spacing and cable schedule, connector pinout and sealing method before track punching or bulk cable production.
Information required before quotation
- roof elevations, total point count and zone lengths
- approved point spacing, wall offset and viewing positions
- selected DC24V or DC36V production version
- controller model, port plan and animation reference
- branch point count, driver locations and cable routes
- housing/track color, corners and mounting detail
- connector, pinout, service loop and drainage method
- sample date, production quantity, spares and delivery
These inputs link the visible roofline rhythm, WS2811 sequence, theoretical branch load and service plan. They prevent a permanent installation from being released as a loose product string with no recoverable zoning.
Frequently asked questions
Does the 35x30mm size define point spacing?
No. It defines the housing; spacing must be approved from the façade mock-up.
Should the project use 24V or 36V?
The page contains both voltage wording and a DC24V row, so select one signed production version before electrical design.
What is the theoretical load of 50 points?
If 2W applies per point, the load is 100W, about 4.17A at 24V or 2.78A at 36V.
Does IP68 make the whole roofline waterproof?
No. Connectors, splices, drivers, penetrations and drainage require their own protected design.
