NLSW-2520 RGBWW DMX Flexible Wallwasher
4-in-1 RGBWW Chip · DMX512 Professional Control · Flexible Format · 16 Million Colours + Full Warm White
What Is the NLSW-2520 RGBWW DMX Wallwasher?
The NLSW-2520 is a flexible LED wallwasher strip built around 4-in-1 RGBWW chips housed in a 25×20mm asymmetric profile. The "wallwasher" optic design directs light evenly across vertical wall surfaces — eliminating the bright-top/dark-bottom gradient of standard strips. DMX512 control gives professional-grade programmable colour and white output across every channel independently.
The RGBWW 4-in-1 Chip — Four Channels in One Lens
Four independent LED emitters — Red, Green, Blue, and Warm White — packed into a single optical lens. Mixed at source, not at distance.
Saturated red for dramatic accent lighting, fire effects, brand-colour wash, and mixed warm sunset tones. DMX channel 1.
Full-spectrum green for nature themes, biophilic walls, architectural brand colours, and combined with red/blue for complex mixed hues. DMX channel 2.
Deep blue for hospitality ambiance, poolside features, night-sky themes, and mixed cyan/purple/teal tones with red and green. DMX channel 3.
High-CRI warm white for natural accent and task lighting. Mix with RGB to create pastel tones, skin-flattering hues, and natural colour-plus-white scenes. DMX channel 4.
Mix R+G+B for pure colours · Add WW for pastel and natural tones · Use WW alone for warm white accent · Full 8-bit (0–255) per channel via DMX for precision colour matching to any brand, scene, or mood

NLSW-2520 Wallwasher vs. Standard RGBWW Strip
The wallwasher profile makes a critical difference to the quality of the wall illumination — not just the colour output.
🟣 NLSW-2520 Wallwasher
- Asymmetric 25×20mm optic — designed for wall illumination
- Even top-to-bottom wash — no bright/dark gradient
- 4-in-1 RGBWW chip — no colour separation at any distance
- DMX512 — professional console control, scene programming
- Flexible — follows curved walls and columns
- IP65/IP67 — indoor, outdoor, and humid environments
- Uniform colour across entire wall surface per zone
- Mounting channel positions strip optimally for wall wash
⬜ Standard RGBWW LED Strip
- Symmetric forward beam — not optimised for walls
- Bright directly opposite, dimmer at edges — uneven wash
- Separate RGB LEDs visible from close range (colour dots)
- PWM or analogue control — limited scene flexibility
- Flexible, but no purpose-built wallwasher mounting
- IP ratings available, but without wallwasher housing
- Colour separation visible on wall if viewed closely
- Strip placement affects wash quality significantly
Why Specify NLSW-2520?
16M+ Colours + Warm White
Full RGB spectrum PLUS warm white in a single chip — pastel tones, skin-flattering mixed whites, and brand-accurate colours all achievable from one installed product.
DMX512 Professional
Industry-standard protocol compatible with every professional lighting desk, software controller, and AV integration system worldwide. The same protocol used in concerts, theatres, and five-star hotels.
Even Wall Wash
Asymmetric optic delivers a uniform top-to-bottom wall wash — no hot spot at the profile level and no dark zone at top and bottom of the illuminated surface.
Flexible — Curves Too
Flexible FPC construction follows curved walls, columns, arched alcoves, and organic forms with a minimum bend radius of 100mm — standard rigid wallwashers cannot follow curves.
IP65 / IP67
Weatherproof versions for outdoor architectural wash, façade feature lighting, covered exterior installations, and humid interior environments like spa walls and pool surrounds.
Chainable Universes
Multiple NLSW-2520 zones chain on the same DMX universe — up to 128 RGBWW zones per 512-channel universe. Large installations handled with standard DMX infrastructure.
Technical Features
🔢 4 DMX Channels/Zone
R, G, B, and WW each consume one DMX channel per zone. A 512-channel DMX universe handles up to 128 independent RGBWW zones from one data feed.
⚡ 24V DC Input
24V constant voltage — lower current draw per metre vs 12V, less voltage drop on long runs, and safer for commercial and outdoor permanent installations.
📐 25 × 20mm Profile
Asymmetric cross-section — 25mm depth from wall, 20mm height. Houses the RGBWW strip and angled optic in a compact form that mounts within standard cove and channel dimensions.
🔄 8-Bit Dimming
256 levels (0–255) per channel via standard DMX — smooth, precise colour mixing without visible stepping across the full output range of each RGBWW channel.
🌡️ Thermal Management
Aluminium extrusion body acts as heatsink for the RGBWW strip — critical for colour stability, as LED colour temperature and output shift as chips heat up without thermal management.
🔌 3-pin XLR DMX
Industry-standard 3-pin XLR DMX input and thru-put on the decoder — daisy-chain multiple zones without additional splitters. Compatible with all DMX cables and connectors.

Installation Guide
🔌 Hardware Installation
- Mount the NLSW-2520 wallwasher at the required height from the wall — typically 200–400mm from the wall face, depending on the wall height to be illuminated. The further from the wall, the wider the wash coverage but the lower the peak intensity.
- Secure the profile using the supplied mounting clips at 300mm intervals. For ceiling-edge cove mounting, fix the clips to the ceiling face so the profile projects forward with the wallwasher optic facing the wall.
- Connect the 24V DC driver output to the RGBWW DMX decoder input terminals. Use a driver rated at minimum 120% of the total strip wattage across all connected zones. Position the driver in a ventilated, accessible location for maintenance.
- Connect the DMX data cable — standard 2-core shielded cable (e.g., Belden 9842 or equivalent) — from the DMX controller or previous fixture's thru-put to the decoder's 3-pin XLR input. Terminate the last decoder in the chain with a 120Ω DMX terminator.
- Set the DMX start address on each decoder's DIP switches or digital address display. Zone 1 = address 1 (channels 1-4 = R,G,B,WW), Zone 2 = address 5 (channels 5-8), and so on. Document all addresses in the project's lighting schedule.
- Power on the system. Send a test signal from the DMX controller (full white = R255, G200, B150, WW255). Verify uniform colour on the wall wash surface and check for any zones not responding (usually a DMX addressing or cabling issue). Seal all IP cable connections per the project's IP rating requirement.
🎛️ DMX Programming Guide
- Create a fixture profile (personality) for the NLSW-2520 in your DMX software — 4 channels per fixture: Ch1=Red (0–255), Ch2=Green (0–255), Ch3=Blue (0–255), Ch4=Warm White (0–255). Most consoles have generic RGBW profiles — use these, assigning your WW channel as the 'W' channel.
- Programme essential scenes first: Scene 1 (Warm White: R0 G0 B0 WW255 — standard ambient), Scene 2 (Full Colour: varies by design), Scene 3 (Brand Colour: set R/G/B to match the venue's Pantone/hex code), Scene 4 (Off: R0 G0 B0 WW0).
- For smooth colour transitions, programme cross-fade times between scenes — typically 3–5 seconds for atmospheric transitions, 0.5 seconds for dramatic snaps, and 30+ seconds for slow ambient colour drifts in spa and restaurant environments.
- For multi-zone installations (e.g., 10 separate wall panels each with their own address), programme each zone individually and then group them in the console for simultaneous control. You can then offset the chase timing by zone for wave effects across multiple walls.
- For automated operation in hotels and retail, programme a time-based macro: 07:00 → Scene 1 (warm white, 80%), 12:00 → Scene 1 (full bright), 19:00 → Scene 3 (brand colour, 60%), 23:00 → Scene 4 (off). Most DMX consoles and Art-Net controllers support time-triggered macros.
- Document the final lighting design: scene list, DMX addresses, cable routes, and decoder locations. Provide this to the venue's facilities team for ongoing management. For complex hospitality installations, schedule a commissioning session with the Nucleo technical team.
🎨 When the Wall Is the Medium
Most lighting treats the wall as a surface to be illuminated. The NLSW-2520 treats it as a canvas. When RGBWW light washes evenly from floor to cornice in a colour that was chosen, programmed, and timed exactly — the wall stops being architecture and becomes atmosphere. The room changes mood. The event changes character. The hotel lobby shifts from daytime business to evening luxury without a single person touching a switch.
The combination of 4-in-1 RGBWW chips and DMX512 is what separates architectural colour lighting from decorative lighting. Decorative lighting glows. Architectural lighting is designed, programmed, and directed with intent. The NLSW-2520 is a professional-grade tool for that intent — supplied with full technical support for project design, DMX commissioning, and installation across India.
