Everything we see is light; without it there can be no sight. All light is not the same, and all lights are not the same which is why you can now choose between three core ranges plus limited edition models.
Choose the High Definition if you want a light that is as good as a reading light gets. It projects a light with a spectral power distribution which closely mirrors the daylight spectrum itself. The Alex Light is available in a wide variety of formats and Classic Lights offer minimum disturbance to others.
It is no accident that these lights are recommended by over 400 Independent Optometrists.
