Good colour might be science, but we got it down to a fine art.

Our colours have tested up to 5x more powerful than other smart brands across flagship products. Yep, even that brand you’re thinking of now. How do we know? As part of our process, we do RGB specific Lumen output testing in our spectrometer across products by leading competitors.

What can more powerful colour do for me?

At LIFX, we feel the power of colour strongly impacts the usefulness of smart lighting. More power in colour means less gimmicky lights in the world that end up in landfill and more atmospheric light you can actually use for real benefits. Benefits like improving sleep, focusing on work, upping the ante on workouts and creating a home full of flexible spaces that would otherwise remain the same, day in, day out.

About Circadian Rhythm

Polychrome Technology™

At LIFX, we pioneered blended color in the smart home with our first ever LIFX Z lightstrip. We then took this to another level with our Colour Candle that has 27 addressable colour zones. We call this Polychrome Technology™.

Create gradients of complementary colours to accent your space. Or have fun with your team colours on game night.

    For the brightest, most vivid colours, nothing can compete with the Lifx Lightstrip with Colour Zones.

  • Mashable

    Other smart lights I’ve used are disappointingly dim when you switch to a fun colour, but the LIFX bulbs stay bright no matter what colour you choose.

  • Better Home & Gardens

    This means you can create endless colour and intensity options to fit all your lighting needs, from a romantic dinner to an energising workspace.

We use superior hardware.

We select premium LEDs specifically to boost colour and open up a broader spectrum. Unlike many other smart lights, we don’t use pre-made RGB LED kits (aka ‘the easy way’). We select each individual LED based off very specific performance requirements to create a more potent colour experience (what we’d call ‘the LIFX way’.) Deeper primary colours mean you can mix a broader spectrum of richer shades, and we wanted all of them.

Our bulbs self-stabilise their colour output.

Colours shift over time as LEDs heat up. So we created an algorithm that uses data from internal heat sensors to actively calibrate colour, adjusting the various LEDs over time to counteract this drift. When you turn on a LIFX light, you’re setting off a chain of mathematical calculations that will ensure your flamingo pink is going to stay at maximum flamingo—not slide off into salmon, fuchsia, mink or coral.

We can blend subtle tones (like our broadest range of whites.)

These extra-vibrant LEDs and highly controlled colour rendering also gives us other strengths. We blend them in with our white LEDs to get the warmest ambers and the coolest icy whites in the industry. This means more invigorating high-energy whites and deeper relaxing evening tones than any other smart bulb.

We use a unified colour space and calibrate each product.

It’s not superior colour if you set your living room to yellow and the lamp turns gold while the ceiling goes to shades of neon green. But this is exactly what can happen when colour handling is tuned for each product without comparison. We have an entire engineering phase (all in-house) to test and tune each new product to our LIFX colour space and blending logic.
