Ambered GU10 Bulb – Three Evening Modes. One Better Light.

If your only goal is to light up a room, an ordinary GU10 LED will do the job. But that’s never what we set out to build. We looked beyond brightness. We looked at the blue light. The invisible flicker.

And what it means to spend evening after evening beneath artificial light that was never designed with human biology in mind. So we built a different kind of GU10 bulb. Today, most of us spend more than 90% of our time indoors. That means the light in our homes has become part of our daily environment, not just something that helps us see.

That’s why every Ambered GU10 includes three built-in modes. Amber when you want a warm, comfortable light for reading, cooking, or relaxing. Deep Red 670nm when the day is over and it’s time to help your body prepare for sleep. Or Amber + Deep Red when you want the warmth of amber light together with the deeper glow of 670nm red light.

Every mode is completely free of blue light. Every mode is flicker-free. Every mode was created for evenings, not office ceilings.

Despite using just 5 watts, the bulb is designed to deliver thousands of hours of comfortable evening lighting. With an expected lifetime of around 25,000 hours, that’s approximately six years of daily use at 10 hours per day. Six years without blue light after sunset. Six years without invisible flicker. Six years of evenings that feel softer, calmer, and easier on your eyes.

Because when you spend thousands of hours under artificial light, the spectrum of that light matters. Take 14 nights to experience the difference in your own home.

If it doesn’t become your favourite evening light, simply return it. We’re not saying it’s the perfect bulb. We simply believe it creates one of the most comfortable evening environments you’ll ever bring into your home.
