RGB and RGBW: What's the difference?

There are two main categories of colour changing LED strip: RGB and RGBW. An RGB LED strip has three different types of light-emitting chip: red, green, and blue (sometimes called “three-in-one” LED). By blending light from all three chips, you can create a rainbow of different colours. These are ideal for ambient uplighting, downlighting, or lighting up the inside of signs and decorative features.

RGBW strips add a fourth chip—cool white—which gives you the versatility of switching from decorative colour to standard white light as needed. This is especially useful for venues that want to shift from a vibrant mood to more practical lighting as the day changes.

Benefits and Main Uses

One of the main benefits of any LED lighting is outstanding energy efficiency for dynamic lighting effects. LED strips also have a long lifespan, so there’s much less faffing with bulb changes.

Colour changing LED strips come in multiple colours as standard and can help you set the perfect atmosphere. They’re a popular choice for event venues and weddings, as they can be set to cycle through colours for a party vibe or matched to a specific theme. The flexibility of the strips makes them easy to fit into awkward spaces, curves, or built-up letters.

Key Things to Consider

Where will you use them?

Some LED strips are suitable for outdoor use, but always check the IP rating. For wet or steamy environments (like bathrooms), look for IP65, IP66, or IP67 to ensure proper waterproofing.

How are they installed?

Different strips use different mounting methods—some have strong adhesive backs, others can be fixed with clips. Consider how much flexibility you want (e.g., if you plan to move the lights). Some strips come in one-metre lengths; others in five-metre reels. Be aware of cut points, as these determine the minimum increments for adjusting length.

Voltage and Wattage

Most colour changing LED strips run at 12V DC, but 24V options exist. Good suppliers will list wattage and lumens per metre, helping you compare energy use and brightness.

Frequently Asked Questions

How energy efficient is LED strip lighting?

LED strips use up to 85% less energy than traditional bulbs and 15% less than compact fluorescents. Their long life also means fewer replacements and less maintenance.

Why do my LED lights glow when off?

This often happens with dimmer or remote setups, as a small current can remain in the strip even when ‘off’. Using a hard switch, or consulting an electrician for wiring issues, usually solves the problem.

Are LED strip lights safe?

Yes, provided they’re installed correctly. Always consult a qualified electrician if you’re unsure—especially if connecting to mains power.

How bright are LED bulbs?

For general household use, most LED bulbs are between 5W and 15W, emitting 300–500 lumens. Outdoor floodlights can emit much more (20,000+ lumens).

Are warm white LED lights bad for your eyes?

No—they aren’t powerful enough to cause permanent damage, but as with any light, avoid staring directly at them for long periods.
