How Many 36W, 24V DMX Wall Washers Fit on a Feed?
Planning a 24V DMX facade row? Start with a nominal load schedule using 36W per fixture, then have the supplier check each real cable run. If the selected SKU's current, connectors and wiring are not confirmed, stop at budget planning rather than ordering from the arithmetic alone.
30-second answer
- For whom: Facade buyers and integrators coordinating fixture count, power branches and DMX control.
- Published direction: The L-W-10036-DMX page lists 36W, DC24V, RGB and DMX512, with 15°, 30°/45° beam and IP65/IP66 variants.
- Stop before order: Do not freeze supply, cable gauge or quantity until the exact SKU, current/wiring data, run lengths and protection version are confirmed.
Have a facade drawing? Send fixture count per branch, spacing and cable lengths to request an SKU-specific load schedule and quotation.
Choose the wall result before the fixture count
The page lists RGB with DMX512 and 15°, 30° and 45° beam options. A narrower beam concentrates light over a smaller area; a wider beam covers more broadly. Uniformity still depends on wall setback, spacing and aim.
Mark facade height, fixture-to-wall distance and target coverage on an elevation first. The beam changes the visual footprint, so fixture count alone cannot establish an even result.
Quote one deliverable combination
The page lists 36W, DC24V, RGB and DMX512 alongside beam and IP variants. An option list is not a compatibility matrix; each quote line should identify one exact model, beam and protection version.
Group fixtures by exposure and maintenance access. A consistent SKU may simplify spares, while different exposure zones may require different versions. Reconcile each quote line with the drawing instead of assuming every option combines.
Use 36W / 24V as a nominal current screen
Nominal current is power divided by voltage: 36W ÷ 24V = 1.5A per fixture. Ten units total 360W, or 15A nominal at 24V, before driver behavior, design margin, losses or cable drop.
List units and cable length by branch, then ask the supplier to size the supply and conductors for the exact SKU. Without that data, 15A is a budget screen, not a supply-selection result.
Draw power branches separately from DMX data
DMX512 describes control communication, not the power path. The page confirms DMX control but does not publish channel use, addressing rules, maximum cascade length or connector pinout; the protocol name cannot answer those questions.
Show 24V branches, data direction, controller position and fixture IDs separately. Request wiring and control documents for the exact SKU; validate the layout with a sample if connector or data topology remains open.
Screen nominal load, then request a circuit check
Buying implication: submit fixture count per branch, longest run, feed locations and target SKU. Ask the quotation to return the rated supply arrangement and wiring plan. Do not convert these ampere figures directly into cable or breaker specifications.
This is arithmetic from the published rating, assuming every unit uses this 36W/24V version. Actual input current, supply margin, cable length and gauge, connectors and temperature are not included.
Planning example: each unit is treated as the published 36W, 24V model; no margin, loss or voltage drop is included.

Decision matrix
| When this fits | Choose this direction |
|---|---|
| Narrow emphasis | Compare 15° at the actual wall setback and verify coverage with a sample. |
| Wider wash | Compare 30°/45° against fixture spacing and uniformity. |
| Budget only | Use 36W/24V nominal arithmetic and label margins/drop as excluded. |
| Ready to order | Obtain exact-SKU current, supply guidance and wiring first. |
| Different exposure zones | Confirm the selected IP version and connection parts for each location. |
| Difficult access | Include access, spares and replacement labor in system pricing. |
Turn the L-W-10036-DMX into a quoteable facade schedule
This model makes color control, beam choice and 24V distribution relevant to the same facade discussion. The page does not give current and complete wiring limits for every version, so this planning table is not a construction drawing or power approval.
Send branch counts, spacing, longest run, wall setback, target beam and exposure zone. Ask for the exact SKU, option matrix, dimension/wiring drawing, BOM, supply/cable recommendation, sample and acceptance plan, full-system quote, spares and lead time.
| Parameter | Published value |
|---|---|
| Model | L-W-10036-DMX |
| Power / input | 36W / DC24V |
| Control / color | RGB / DMX512 |
| Beam options | 15°, 30°, 45° |
| Protection versions | IP65 / IP66 options |
| Construction | Aluminum-alloy housing; adjustable bracket |
Access and environment affect installed cost
The page lists IP65/IP66 versions, an aluminum-alloy housing and an adjustable bracket. The fixture rating does not automatically establish the rating of field connectors, junction boxes or the complete run.
For high or difficult-to-service locations, include bracket access, junction-box placement, spares and replacement labor in the BOM. State the protection of each connection component instead of assigning one rating to the whole system.
What a useful quote returns
- 01SKU and option matrix: model, wattage, voltage, beam and IP version on each line.
- 02Drawings and BOM: facade positions, branch lengths, power/data wiring and accessories.
- 03Commercial validation: representative sample, acceptance points, complete-system price, spares and lead time.
Match the option schedule to the installation drawing before comparing installed-system cost, not fixture price alone.
FAQ
15°, 30° or 45°?
Compare wall setback and target coverage, then validate with a sample. The page lists these angles but no universal spacing rule.
Does 15A mean I should buy a 15A supply?
No. It is nominal arithmetic for ten 36W units at 24V; margin, actual current, cable loss and branch design remain SKU- and layout-dependent.
