RGBW LED Sheets (RGB + White)

An RGBW LED sheet combines multi-color (Red, Green, Blue) LEDs with a separate, dedicated white LED on the same circuit. The big advantage is you get true, high-quality white light for functional tasks, not the muddy, bluish-white that regular RGB lights create by mixing colors. It's the best of both worlds: vibrant accent lighting and clean, usable white light from the same fixture.

It's very similar, you just have one extra wire to manage. An RGBW LED sheet uses a 5-pin connection instead of a 4-pin one. You'll have terminals for Red, Green, Blue, White, and a common positive (+24V). It's crucial to connect each wire to the matching terminal on your controller. We have a detailed guide on how to wire RGBW strips that covers the whole process, with diagrams.

You need a controller with 5 outputs (R, G, B, W, V+), specifically labeled for RGBW. A standard 4-pin RGB controller won't work because it can't manage the separate white channel. We stock over 2,600 control units, so whether you need a simple RF remote, a DMX decoder for a commercial job, or a Wi-Fi controller that works with an app, we have an RGBW controller series that will do the job.

Yes, absolutely. Our RGBW flexible LED sheets are designed to be cut. You'll see designated cut lines, usually marked with a scissor icon, between the LED segments. Just use a sharp pair of scissors and cut straight across the copper pads. This lets you trim the sheet to the exact size and shape of your project, whether it's a kitchen island or a retail display.

Those terms describe the color temperature of the dedicated white light, measured in Kelvin (K). 'Warm white' (2700K-3000K) is a cozy, yellowish light like a classic incandescent bulb, great for homes. 'Natural white' (4000K) is a balanced, neutral white light good for offices and retail. 'Daylight white' (6000K) is a crisp, bluish-white that mimics bright daylight, used for high-clarity tasks.

Yes, both the color channels and the white channel are fully dimmable. The dimming is handled by the PWM (Pulse Width Modulation) signal from your RGBW controller. You can dim the overall brightness, dim individual colors to create custom shades, and dim the white light independently for task or mood lighting.

This is a wiring mix-up at the controller. If your red button brings up green, for example, your red and green wires are probably swapped on the output terminals. The same goes for the white channel. Double-check that the R, G, B, and W wires from the sheet are landed on the correct R, G, B, and W terminals on the controller. It's a really common mistake, and an easy fix.

That all comes down to watts. Add up the total wattage of all the RGBW LED sheets you plan to connect. For example, if you have three 70W sheets, that's 210W total. Then, choose a power supply that's rated for at least 20% higher than your total load—so for 210W, you'd want a power supply of at least 252W. Sizing the power supply correctly is key to a stable, long-lasting installation.

The key is uniform distance between the LED sheet and the translucent surface. For natural stone like onyx or quartzite, you typically want about 20-50mm of space. We designed our clear plastic support pillars for exactly this. They create the perfect, consistent gap to diffuse the light evenly and eliminate any visible dots or 'hotspots,' giving you that smooth, high-end glow.
