SF-WW1818 LED Wall Washer Light

Professional Wall Wash Lighting

Wall washers do one thing: they throw an even, wide spread of light across a surface. The SF-WW1818 does it with six color channels instead of the usual three or four. RGBWA+UV means you get the full RGB color gamut plus dedicated white for clean, high-CRI illumination, amber for warm tones and natural skin lighting, and UV for blacklight and fluorescent glow effects. That's a range most single fixtures can't touch.

The bar format (~1 meter long) is purpose-built for linear wash applications — line them up along a wall, across a stage front, or along an architectural facade. The 25° beam angle provides a controlled wash that covers surfaces evenly without excessive spill. At 9,456 lumens and a CRI of 90, the output is bright enough for large surfaces and accurate enough for environments where color quality matters — broadcast, photography, corporate events, and houses of worship.

RGBWA+UV — Six Color Channels Explained

Each of the 18 LEDs in the SF-WW1818 contains six independent color dies in a single package. This means every LED can produce any combination of the six colors simultaneously, and all 18 LEDs can be controlled independently in 108-channel mode for pixel-level precision. Here's what each color channel contributes:

Color Mixing Advantages

With six independent color channels, the SF-WW1818 can produce colors that 3-in-1 (RGB) and 4-in-1 (RGBW) fixtures simply cannot match. The dedicated amber die means you don't have to mix red and green to approximate amber — you get a pure amber tone that looks natural and consistent. The dedicated white die means white light has a CRI of 90, rendering skin tones, fabrics, and architectural surfaces accurately rather than with the greenish or magenta tint that RGB-mixed white often produces.

The UV channel opens an entirely separate category of effects. Mix UV with blue for deep blacklight washes. Use UV alone for glow-paint and fluorescent effects. Add a touch of UV to any color mix for a subtle violet edge that adds depth to the color. The UV channel is independently controllable, so you can bring it in and out without affecting the rest of your color mix.

Common Color Recipes

CRI 90 — Why It Matters

CRI (Color Rendering Index) measures how accurately a light source renders colors compared to natural light. A CRI of 90 means the SF-WW1818 renders colors at near-reference quality — skin tones look natural, fabrics show their true color, and architectural surfaces display accurate texture and hue. For events with photography or video, CRI matters enormously: low-CRI fixtures make everything look flat and unnatural on camera, while CRI 90 produces results that look professional without post-production color correction.

DMX-512 Control

The SF-WW1818 communicates via standard DMX-512 protocol over 3-pin XLR connections (in/out for daisy-chaining). The onboard LED display with 4-button menu handles DMX address setting, channel mode selection, and standalone program configuration without needing a console.

Channel Modes

6-Channel Mode

6-channel mode is the simplest — one channel per color, all 18 LEDs act as a single unit. Set your color mix once and the entire bar produces that color uniformly. Ideal for static wall washes, architectural uplighting, and simple color scenes where per-LED variation isn't needed.

108-Channel Mode — Full Pixel Control

108-channel mode unlocks per-LED control across all 18 LEDs. Each LED gets its own 6 color channels (R, G, B, W, A, UV), giving you 18 individually addressable pixels across the bar. This is where pixel mapping software comes in — map video content, generative patterns, or custom color sequences across individual fixtures or multi-bar arrays.

With multiple bars in an array, 108CH mode creates a pixel grid. Four bars stacked vertically give you an 18 × 4 pixel matrix with full RGBWA+UV color at each point — enough for scrolling color gradients, text, simple video content, or architectural animation effects.

Non-DMX Control Modes

Frequently Asked Questions

What does "RGBWA+UV" mean?

It means each LED contains six separate color dies: Red, Green, Blue, White, Amber, and Ultraviolet. Each color is independently controllable. This gives you a much wider color palette than standard RGB or RGBW fixtures — true amber tones, clean high-CRI white, and UV blacklight effects, all from one fixture.

Can I use this outdoors?

The SF-WW1818 is rated IP33 — it's designed for indoor use. It can tolerate some dust exposure but is not waterproof. For outdoor events, use it under a covered stage, tent, or weather-protected structure. Direct rain or moisture exposure will damage the fixture.

Do I need a DMX controller?

No. The SF-WW1818 operates in four modes without DMX: auto-run (built-in color programs), sound-active (reacts to music), master/slave (multiple bars synced), and manual via the onboard 4-button display. DMX gives you precise color control and scene programming, but the fixture works impressively without it.

What is CRI 90 and why does it matter?

CRI (Color Rendering Index) measures how accurately colors appear under a light source compared to natural light. A score of 90 out of 100 means the SF-WW1818 renders colors with near-natural accuracy. This matters for events with photography/video (skin tones look natural), retail (products show true colors), museums (artwork is accurately lit), and any situation where color quality is important.

How many can I fit in one DMX universe?

Depends on channel mode. In 6CH mode: 85 bars per universe. In 10CH mode: 51 bars per universe. In 108CH mode: 4 bars per universe (4 × 108 = 432 of 512 available channels). For large pixel-mapped arrays in 108CH mode, you'll need multiple DMX universes.

How many can I daisy-chain on one power circuit?

Each bar draws approximately 216W at full output. The PowerCon in/out connectors allow daisy-chaining. On a standard 15A/120V circuit (1,800W available), you can safely run up to 7 bars per circuit with 20% headroom. On a 20A circuit, up to 9 bars. Always confirm total circuit load before the gig.

How does the UV channel work?

The UV (ultraviolet) die in each LED emits short-wavelength light that makes fluorescent materials glow — white clothing, UV-reactive paint, fluorescent tape, and specialty decor. You can run UV alone for full blacklight effect, or mix it at low levels with other colors to add a subtle violet tint. The UV channel has its own DMX channel, so it's fully independent from the other five colors.

Is the fan noisy?

The SF-WW1818 uses an intelligent temperature-controlled fan. The fan adjusts speed based on actual fixture temperature — it runs quietly at low temperatures and speeds up only when needed under sustained high-output operation. For noise-sensitive environments, running the fixture at moderate intensity keeps the fan near-silent.

What makes this better than separate RGB and UV fixtures?

Integration. With separate RGB and UV fixtures, you need twice the mount points, twice the cable runs, and two DMX addresses per location. The SF-WW1818 puts all six color channels in every LED, so your color mix and UV effect come from the same optical point — no alignment issues, no shadow conflicts, and half the infrastructure.

Can I pixel-map the SF-WW1818?

Yes — in 108CH mode. Each of the 18 LEDs becomes an individually addressable 6-channel pixel. Use pixel mapping software (Resolume, MadMapper, Jinx!, etc.) to map content across single bars or multi-bar arrays. Each pixel has full RGBWA+UV control.

Getting the Most From the SF-WW1818

Distance Determines Coverage

The 25° beam angle means the wash spread depends on throw distance. At 3 feet from a wall, each bar covers approximately 16 inches of surface height. At 6 feet, coverage expands to roughly 32 inches. At 10 feet, you're washing about 53 inches of wall. For full floor-to-ceiling coverage on a standard 8-foot wall, place fixtures about 6–8 feet from the wall — or use two rows at different heights for even coverage without hot spots.

Spacing for Seamless Wash

When lining up multiple bars, overlap their coverage zones slightly to avoid dark gaps between fixtures. For a ~1-meter (39-inch) bar with a 25° spread, placing units roughly 3–4 feet apart (center to center) at a 6-foot throw distance produces a smooth, seamless wash across the surface. Tighter spacing gives more even coverage; wider spacing creates visible pools between fixtures.

Start With 10-Channel Mode

Unless you need per-LED pixel control, 10-channel mode is the sweet spot. You get full RGBWA+UV color control plus master dimmer and strobe — enough creative flexibility for most shows and installs without burning 108 channels per fixture. Move to 108CH when you're ready for pixel mapping or need individual LED precision.

Use White + Amber for Warm, Natural Light

The temptation with RGBWA+UV is to max out the color channels. But the white and amber channels are where this fixture earns its money for professional events. White at 70% plus amber at 30–40% produces a warm white that matches tungsten sources and flatters skin tones naturally. This is your go-to recipe for weddings, corporate events, and any environment with cameras.

UV Subtlety Goes a Long Way

Full UV at 100% is great for dedicated blacklight moments, but try mixing UV at 10–20% into your color washes for a subtle effect. A deep blue wash with a touch of UV has a richness and depth that straight blue can't match. The UV adds a luminous quality to the wash that's visually striking without being obviously "blacklight."

Master/Slave for Automated Installs

For permanent installations in bars, lounges, retail, or lobbies: set one bar as master in auto-run with a slow fade program, daisy-chain the rest as slaves. Every bar follows the master in perfect sync. Change the look anytime from the master's display — no DMX console, no laptop, no operator. It just runs.

Mind the Airflow

The SF-WW1818 uses fan-based cooling with intelligent temperature management. When mounting, ensure the fan vents aren't blocked by adjacent fixtures, walls, or mounting hardware. Restricted airflow causes the fans to run harder and louder. Leave at least 2–3 inches of clearance around the fixture body for proper ventilation, especially in enclosed installations or when multiple bars are stacked closely.
