The Serious Readers Risk-Free Home Trial

Your verdict is the only one that matters.

Order any HD Light and try it in your home. The HD Original and HD Pro get a full 90 days because your eyes need time to adjust to a new quality of light. The HD Essential gets 30. If it does not make a tangible difference to the clarity of your sight, we collect it from your door and refund you in full. UK mainland only.


How the Trial Works

The only test that matters

We can show you the spectral analysis and the lab reports. But the only meaningful test happens in your home. It comes down to how the light performs for your eyes, in your favourite chair, with the book or task in front of you. The HD Original and HD Pro get 90 days because it takes time for your eyes to fully adapt to a new quality of light.

The HD Essential gets 30. Either way, the trial exists so you can prove the engineering to yourself. If it does not make a tangible difference, you get every penny back.

The proof is in the numbers

98 out of every 100 people who try one of our lights decide to keep it. That is not a marketing claim. It is the simple outcome of this trial process, repeated thousands of times.

It is the clearest evidence we have that the engineering delivers a difference you notice from the first evening and still notice months later. Backed by more than 500 independent opticians who see the consequences of poor light every day and recommend our lights to their patients.

I was put off by the price for years. It's worth every penny. I wish I'd bought one years ago.
