Three well-designed light therapy lamps for your desk, with their lux at a stated distance, exactly as the manufacturers publish them.
Our pick: Lumie TaskSee on Amazon
Our pick
Lumie Task
If you work at a desk all day, the Lumie Task in White Mist is the simplest choice: it is a real adjustable, dimmable desk lamp that delivers 10,000 lux at 15 cm according to Lumie, with broad-spectrum CRI 95+ LEDs and no UV. It lights your work surface all day, without adding a second device to the desk.

Other situations
If you want an object that gets noticed, the Lumie Halo plays the design card with its copper ring, a Day Mode and an Evening Mode. If medical device status and a large illuminated surface matter to you, the Beurer TL 95 claims 14,000 lux at about 20 cm, in a bulkier format.

How these were chosen
- Lux always paired with a distance
- A figure of 10,000 lux means nothing without the measuring distance: the further away you sit, the lower the intensity. Compare lamps at the same distance, and look at where you will actually be sitting.
- Comfortable light for working
- At the desk, the lamp stays on while you read or type. UV-free, flicker-free light with good colour rendering (high CRI) is less tiring than a simple, very powerful panel.
- Space and looks on the desk
- A lamp you find ugly ends up put away, and a missed session does nothing. Pick a size that fits your desk and that you are happy to leave out on display.
Why lux mean nothing without a distance
Spec sheets highlight 10,000 or 14,000 lux, but illuminance drops quickly as you move away. Lumie, for example, states 10,000 lux at 20 cm for the Halo, then 5,000 lux at 32 cm and 2,500 lux at 50 cm. A lamp showing more lux at a shorter distance is therefore not necessarily brighter where you sit.
In this guide, each value is quoted with the distance given by the manufacturer, with no conversion. Before buying, measure the distance between your chair and where the lamp will stand: that is what decides which model suits your desk.
Desk lamp or session lamp
There are two ways to fit light therapy into your working day. The first is a desk lamp that produces very bright light, like the Lumie Task: it lights your keyboard and papers, and you use it without changing your habits. The second is a lamp you place in front of you for a session, like the Halo or the TL 95.
A session lamp offers a larger light surface, but it takes up a corner of the desk and does not replace your usual lighting. In an open-plan office or a small study, the desk lamp is often the easier option to live with.
How these three were chosen
Three light therapy lamps available on Amazon, from two manufacturers that publish their lux at a stated distance, the colour temperature and the absence of UV. Sunrise simulators and ordinary desk lamps are excluded. On their official pages, only the Beurer TL 95 is presented as a medical device.
None was tested in a lab. The characteristics quoted come from the manufacturer pages and the Amazon listings, nothing else, and no health claim is made beyond what the manufacturers write. Each card below also says when not to choose it.

Frequently asked questions
Which light therapy lamp should office workers choose?
One that fits on the desk and that you will actually use. The Lumie Task works as both a desk lamp and a light therapy lamp, which saves an extra device. The Lumie Halo suits people who want a beautiful object with an Evening Mode, the Beurer TL 95 those who want a medical device with a large illuminated surface.
How far away should a light therapy lamp be on a desk?
Each manufacturer measures its lux at a precise distance: 15 cm for the Lumie Task, 20 cm for the Lumie Halo, about 20 cm for the 14,000 lux of the Beurer TL 95. For the Halo, Lumie also states 5,000 lux at 32 cm and 2,500 lux at 50 cm. Lumie advises starting with 30 minutes a day, at full brightness and at arm’s length (about 50 cm). Follow your lamp’s instructions.
Should I see a doctor before using light therapy?
Yes if you think you have seasonal depression or depression, if you have an eye condition or disease, or if you take a photosensitising medication: talk to your doctor before you start. These lamps replace neither a diagnosis nor a treatment, and this guide gives no medical advice.
Can you use a light therapy lamp in the evening?
Lumie advises against using the Halo in Day Mode into the evening, as you may struggle to fall asleep, and offers a low-blue Evening Mode for that time of day. Manufacturers generally recommend sessions in the morning or early in the day.
Can a light therapy lamp replace a desk lamp?
Only the Lumie Task is designed as an adjustable desk lamp. The Halo and the TL 95 are lamps you place in front of you for a session: keep a regular desk lamp to light your work surface the rest of the time.
