What kind of light you read by matters as much as how much of it you have.
By 60, your eyes need about three times the light they needed at 20. A stronger bulb gives you more of it, but you can still find yourself reading the same line twice.

See what ordinary light leaves behind.
An ordinary LED only looks white. It starts with a blue chip, so its light carries a spike of blue and too little of the other colours, especially red. The HD Pro's Daylight Wavelength Technology™ fills those gaps, so you get every colour, much as you do from daylight.
That is why reading by a window on a clear morning is so easy, and the HD Pro gives you that light at any hour. Colours look true, fine detail is easier to pick out, and with no flicker the light stays steady for as long as you read.
| Measurement | The HD Pro | The ordinary LED we measured |
|---|---|---|
| Colour fidelity (Rf) | 98 | 83 |
| Colour gamut (Rg) | 101 | 97 |
| Deep-red rendering (R9) | 92 | 40 |
| Colour temperature | 4,193 K | 7,648 K |
The HD Pro's light engine was measured on 27 November 2023 on an Everfine SFIM-300 at 500 mm, sample HD Wide Beam (S-1). The ordinary LED was measured on 29 October 2018 on the same instrument, at 20 inches.
Daylight scores 100 for colour accuracy. On deep reds, the HD Pro scores 92 and the ordinary LED we measured scores 40.
Set it exactly how you like it without getting out of your chair.
You bring the head exactly where you need it, shape the beam and set the brightness, and the HD Pro stays just as you left it. Pick any control below to see it close up.

Here is the HD Pro, figure by figure.
Hover over or tap any figure to see what it means for you.
- Light engine
- 7.2W LEDIt is the LED and lens that make your light. At 7.2 watts it costs pennies a week to run, and you can replace it at home.
- Lux at 50cm
- 3,600 to 7,200Lux is the amount of light that reaches your page, measured 50cm from the head. The narrower you set the beam, the higher it goes.
- Lumens
- 630Lumens are all the light the lamp gives out, and the lens gathers it into a beam, so it reaches your work rather than the ceiling.
- CRI
- 98The Colour Rendering Index measures how true colours look under a light, out of 100, where daylight is the perfect score. The ordinary LED we measured scores 88.
- Colour temperature
- 4,000KIt describes how warm or cool the white looks. At 4,000K your light is a neutral white, between the yellow of a warm bulb and the blue of a cool one.
- Spread of light
- 33 to 61cm (13 to 24in)It is the width of the circle of light, which you set by turning the ring on the head.
- Dimmable
- Yes, steplessStepless means the thumbwheel dims it smoothly to any level you like, rather than in a few fixed steps.
- Cordless battery
- Optional, 6.5 hoursWith the optional battery, one charge gives you about six and a half hours of full-strength light, and it recharges in 90 minutes.
- Height
- 152cmIt stands 152cm tall, and the arm bends to bring the head down to your work.
- Weight
- 4.8kgThat is the whole light on its base, heavy enough to stand steady beside your chair.
- Cable length
- 2.8m (9ft)That is the length from your light to the plug, which gives you plenty of choice about where it stands.
- Warranty
- 5 years, arm for lifeThe whole light is covered for five years, and the arm is guaranteed for life. We have been making lights for reading for over forty years.

0800 032 9366What makes it different from an ordinary reading lamp?
Three things. The light itself scores 98 out of 100 for colour accuracy, where daylight scores 100, so colours look true and similar shades are easy to tell apart. It puts up to 12x more light on your page than a 60W bulb, instead of spreading it around the room, so small print is sharper. And you set the beam and the brightness to suit your eyes and whatever you are doing.
Will I really notice the difference?
Most people notice it the first time they switch it on: the light lands where they are looking and the print is easier to make out. 99.4% of the people who try one keep it for the difference it makes.
Is it a lot of money for a lamp?
It is, because it is built from 224 specially designed parts and it is modular, so key parts can be serviced or replaced at home for years to come. You can still try it at home for 90 days before you decide, and we collect it free from any UK mainland address if it is not right for you.
How the home trial worksWill it help if my room is already bright?
It can. A bright room can still leave your book in shadow. The HD Pro puts daylight-quality light straight onto your page, which is where your eyes need it.
How long will it last?
For years. The light engine and the battery can both be replaced, the five-year warranty covers the light and its light engine, and the arm is guaranteed for life.
Can I use it away from a socket?
Yes, with the optional battery, which gives you about six and a half hours of full-strength light on a charge and recharges in 90 minutes. You can order it with your light or add it later.
When will it arrive?
Usually within 2 to 3 working days by DHL to a UK mainland address, in two parts that go together in under 30 seconds with no tools. Non-mainland UK addresses usually take up to 10 working days, and for an address outside the UK, call us for a quote.
How is the HD Pro different from the HD Original?
Both have the same light and the same controls on the head. The HD Pro can also run from a battery and be dimmed with a remote, and its modular design means key parts can be serviced at home.
