The Serious Promise
98 out of 100 people who try our lights keep them. That's the result of the engineering, tested thousands of times in real homes.
We back it with a proper trial, a proper warranty, and the trust of over 500 independent opticians.
Try it at home
Order a light and use it in your own home. HD Pro lights get 90 days because it takes time for your eyes to fully adapt to a new quality of light.
All other models get 30 days. If it doesn't make a clear difference to how you see, we collect it at our cost and give you a full refund. UK mainland only.
How the trial works ->
A 5-year warranty
HD Lights are built to be repaired, not replaced. Modular construction means components can be swapped and serviced for years to come.
HD Pro and HD Essential lights are guaranteed for five years against manufacturing faults. If something goes wrong, we collect it, fix it in our Aylesbury workshop, and return it to you. Parts, labour, shipping - all covered.
