Choose the Serious Light that fits the way you read.
All three give you the full spectrum of daylight. Because one light fits nobody, they differ in how much light they put on your page, how you adjust them and whether they need a socket.
A five-year warranty, backed by forty years of making lights.
An ordinary LED, measured
Daylight Wavelength Technology™
The ordinary LED peaks in the blue and falls away in the deep reds. Daylight Wavelength Technology™ spreads its light across the whole visible range. Both were measured on the same instrument.
Each one gives you the full spectrum of daylight.
All three are built on Daylight Wavelength Technology™, which gives you the deep reds an ordinary LED leaves out, so print is crisp and colours are true.
It scores 98 out of 100 for colour, where the ordinary LED we measured scores 83, and Serious Lights have been chosen for operating theatres and the British Museum.

What is the difference between the HD Original and the HD Pro?+
They have the same light and the same beam. The HD Pro adds the option of a remote handset and a battery, now or later, and a modular design whose key parts can be serviced at home. The HD Pro comes in Black, and the HD Original in Black or Heritage White.
Is the HD Essential bright enough for small print?+
It gives 4,800 lux at 50cm across one wide beam, which is 8x more light on your page than a 60W bulb. If you read very small print or do fine close work, the HD Original's beam narrows to put up to 7,200 lux on your page.
Which light do most people choose?+
The HD Original. More of our customers choose it than any other light, for the beam you can shape and the thumbwheel on its head.
Whichever light you choose, you can try it at home first.
Read by it and use it for everything else you love doing, then decide.
