DMX RGBW Wall Washer Procurement: Choose Module Length Before the Facade Order
Quick decision
Freeze the facade into straight segments and access zones before ordering one nominal length. On a hypothetical unbroken 12m line, 2m modules need six fixtures and five internal boundaries; 0.5m modules need 24 and 23. That comparison says nothing yet about actual gaps, power per length or DMX channels.
Published facts and evidence boundary

|---|---|
| Listed model | L-W-10024-DMXRGBW-96W |
| Published options | Single color or RGBW; nominal lengths 0.5m, 1m, 1.5m, 2m |
| Electrical listing | AC85-277V, 50/60Hz; 96W model entry |
| Optics and build | 90-degree beam; aluminum-alloy and tempered-glass description |
| 12m count illustration | 24 x 0.5m, 12 x 1m, 8 x 1.5m or 6 x 2m before gaps |
| Unconfirmed across options | 96W allocation by length/color, DMX channel mode, connectors and exact outdoor assembly |
Mark the facade breaks before choosing a fixture size
A long nominal fixture reduces seams on a plain wall but can cross a window, pilaster or service hatch. Mark the real straight runs, corner returns and night-view positions before converting metres into SKU counts.
The listed 90-degree beam supports a broad wash starting point; it does not define mounting setback, height coverage or color uniformity. Test one representative bay rather than extrapolating from a catalogue image.
Keep length, color and mains input on one order line
The current page lists model L-W-10024-DMXRGBW-96W, single-color/RGBW options, AC85-277V 50/60Hz, 90 degrees and nominal lengths of 0.5, 1, 1.5 and 2m. These are choices, not proof that every combination has identical wattage or circuitry.
Create one row per actually required facade module: length, color version, finish, mounting position and connector orientation. Without that matrix, a 2m straight bay and a 0.5m corner filler can be accidentally treated as electrically identical.
Use length arithmetic for interfaces, not a false power total
For a gapless 12m thought experiment, 12/2 gives six 2m modules and five internal boundaries; 12/0.5 gives 24 half-metre modules and 23 boundaries. Actual installed length adds physical gaps, ends and corners.
The page lists 96W but does not map that number to every published length/color. Multiplying 96W by any count would be an unsupported load estimate. Obtain the rating per ordered module and electrical protection design before sizing circuits; AC input current also needs power factor, not just P/V.
Partition DMX zones with the physical bays
DMX512 is the stated control family for this RGBW model. A lighting desk can assign scenes by facade bay, but one fixture does not equal one universal channel count: channel mode, addresses, termination and isolation depend on the supplied version.
Show each physical module, data-chain direction and accessible service point on the same drawing. Do not infer field cutting from the nominal length options; these are finished fixtures, not a cuttable LED tape.
Treat each extra seam as an outdoor interface
The product title claims an outdoor IP65 version; the list also describes aluminum-alloy and tempered-glass construction. The finished line still includes connectors, glands, brackets and drainage that are not covered merely by the luminaire label.
A 24-module plan has 18 more internal boundaries than a six-module plan on the same ideal 12m line. That may improve corner fitting but also multiplies alignment, sealing and maintenance interfaces; compare both effects on a mounted sample bay.
Conditional project decision table
| Project condition | Decision and evidence |
|---|---|
| Window bays and pilasters interrupt the line | Use shorter modules where necessary and count each resulting seal and bracket. |
| Long uninterrupted straight facade | Test 1.5m or 2m options to reduce fixture count and visual seams. |
| Sheltered display wall | Select by bay geometry and viewing result; do not assume an outdoor assembly is required. |
| Exposed exterior elevation | Specify the actual IP65 build and inspect each connector, gland and drainage path. |
| Many modules on one elevation | Schedule electrical branches from confirmed per-module ratings, not the standalone 96W line. |
| Independent color scenes by facade bay | Freeze RGBW DMX mode, addresses and service access per delivered fixture. |
LIKELIGHT RGBW washer as a facade module family
This LIKELIGHT listing is useful when the designer needs a broad 90-degree RGBW wash and can choose among 0.5m, 1m, 1.5m and 2m modules to follow the building rhythm. The first procurement drawing should be a dimensioned module schedule, not a single line reading '12m wall washer'.
It is not a basis to assert that each length consumes 96W or the same DMX channels. Approve one full bay with the exact RGBW mode, per-module rating, joint details and outdoor construction, then repeat the accepted schedule.
Information required before quotation
- elevation with each straight bay, corner and obstruction
- nominal module lengths and gap allowances
- RGBW or single-color version and target scenes
- mounting setback, height and one approved 90-degree test bay
- rating and quantity for each exact ordered module
- DMX controller, mode, addresses and cable route
- outdoor connectors, glands, brackets and service access
- sample approval, production quantity and delivery phases
These inputs turn the length list into a coordinated optical, electrical and service schedule instead of treating one 96W catalogue line as a complete facade system.
Frequently asked questions
Can six 2m units cover any 12m facade?
Only the ideal straight, gapless calculation. Actual corners, brackets, tolerances and access change the schedule.
Does every 0.5m unit draw 96W?
The page does not establish that. Obtain a rating for each ordered length and color version.
How many DMX channels does an RGBW fixture use?
That depends on its supplied mode and grouping; do not assign addresses from the color letters alone.
Does the IP65 title protect every field connector?
No. Specify and inspect the whole outdoor connection and drainage assembly.
